Lodestones are naturally magnetized pieces of the mineral magnetite . They are naturally occurring magnets , which can attract iron . The property of magnetism was first discovered in antiquity through lodestones. Pieces of lodestone, suspended so they could turn, were the first magnetic compasses , and their importance to early navigation is indicated by the name lodestone , which in Middle English means "course stone" or "leading stone", from the now-obsolete meaning of lode as "journey, way".

80-450: Lodestone is one of only a very few minerals that is found naturally magnetized. Magnetite is black or brownish-black, with a metallic luster , a Mohs hardness of 5.5–6.5 and a black streak . The process by which lodestone is created has long been an open question in geology. Only a small amount of the magnetite on the Earth is found magnetized as lodestone. Ordinary magnetite is attracted to

160-415: A Lambertian reflector . An example is kaolinite . A distinction is sometimes drawn between dull minerals and earthy minerals, with the latter being coarser, and having even less lustre. Greasy minerals resemble fat or grease. A greasy lustre often occurs in minerals containing a great abundance of microscopic inclusions, with examples including opal and cordierite , jadeite . Many minerals with

240-562: A book of admiring letters, poems, and epitaphs by numerous people. In the nineteenth century Charles Lamb enjoyed her Sociable Letters and so much admired her biography of her husband that he called it a jewel "for which no casket is rich enough." James Fitzmaurice argues “Cavendish was viewed sympathetically by the English Romantic poets”. Margaret Cavendish was the first person to develop an original theory of atomism in Britain. She

320-549: A magnetic field as iron and steel are, but does not tend to become magnetized itself; it has too low a magnetic coercivity (resistance to demagnetization) to stay magnetized for long. Microscopic examination of lodestones has found them to be made of magnetite (Fe 3 O 4 ) with inclusions of maghemite (cubic Fe 2 O 3 ), often with impurity metal ions of titanium , aluminium , and manganese . This inhomogeneous crystalline structure gives this variety of magnetite sufficient coercivity to remain magnetized and thus be

400-425: A permanent magnet . The other question is how lodestones get magnetized . The Earth's magnetic field at 0.5 gauss is too weak to magnetize a lodestone by itself. The leading theory is that lodestones are magnetized by the strong magnetic fields surrounding lightning bolts. This is supported by the observation that they are mostly found near the surface of the Earth, rather than buried at great depth. One of

480-435: A "vitreous greasy" lustre). Some minerals exhibit unusual optical phenomena, such as asterism (the display of a star-shaped luminous area) or chatoyancy (the display of luminous bands, which appear to move as the specimen is rotated). A list of such phenomena is given below. Adamantine minerals possess a superlative lustre, which is most notably seen in diamond . Such minerals are transparent or translucent, and have

560-609: A Han tomb. Based on his discovery of an Olmec artifact (a shaped and grooved magnetic bar) in North America, astronomer John Carlson suggests that lodestone may have been used by the Olmec more than a thousand years prior to the Chinese discovery. Carlson speculates that the Olmecs, for astrological or geomantic purposes, used similar artifacts as a directional device, or to orient their temples,

640-442: A child and the book/child and author/parent to birds. The book is like a baby bird just going out on its own. The author, like a parent bird, is unsure whether the book/baby bird will be safe and chirrups an attempt to protect it. This is viewed as "Cavendish's most ambitious attempt to combine modes and genres." It includes short prose romances – "The Contract" and "Assaulted and Pursued Chastity" – and several prefatory addresses to

720-409: A child, she said that it was innocent, young, well-behaved, bashful and sensitive. Readers should blame her, not the book, if they did not like it. If, however, the book was well liked, she made it clear that she expected fame. In her epistle to the poets, Cavendish notes that as women seldom wrote, her writing may be ridiculed, as the strange and unusual seem fantastical, the fantastical seems odd, and

800-440: A creative relationship, even as her writing tutor, for writing "fashions an image of a husband and wife who rely on each other in the public realm of print." A few years after her marriage, she and her husband's brother, Sir Charles Cavendish , returned to England. Cavendish had heard that her husband's estate, sequestrated due to his being a royalist delinquent , would be sold and that she as his wife could hope to benefit from

880-403: A dialogue form between such pairs as earth and darkness, an oak and a tree-cutter, melancholy and mirth, and peace and war. As noted by Mistress Toppe , formerly Elizabeth Chaplain and Cavendish's maid, Cavendish's writings took the form of poetical fiction, moral instruction, philosophical opinion, dialogue, discourses and poetical romances. Poems and Fancies included The Animal Parliament ,

960-503: A dozen original works; with her revised works the total came to 21. She often would have her portrait engraved on the covers of her different works so that people would know that she was solely responsible for the creation of whatever she wrote and then published in some way or another. Cavendish has been championed and criticised as a unique, ground-breaking woman writer. She rejected the Aristotelianism and mechanical philosophy of

1040-558: A fool, which Cavendish stated that she preferred to being seen as wanton or rude. Regretting that she had left home to be a lady-in-waiting, Cavendish informed her mother that she wanted to leave the court, but her mother persuaded her not to disgrace herself by leaving and provided her with funds that Cavendish noted quite exceeded the normal means of a courtier. She remained a lady-in-waiting for two more years before marrying William Cavendish in 1645, then still Marquess of Newcastle. Cavendish noted that her husband liked her bashfulness; he

1120-458: A glassy lustre. A list of these terms is given below. Lustre varies over a wide continuum, and so there are no rigid boundaries between the different types of lustre. (For this reason, different sources can often describe the same mineral differently. This ambiguity is further complicated by lustre's ability to vary widely within a particular mineral species). The terms are frequently combined to describe intermediate types of lustre (for example,

1200-510: A greasy lustre also feel greasy to the touch. Metallic (or splendent ) minerals have the lustre of polished metal, and with ideal surfaces will work as a reflective surface . Examples include galena , pyrite and magnetite . Pearly minerals consist of thin transparent co-planar sheets. Light reflecting from these layers give them a lustre reminiscent of pearls . Such minerals possess perfect cleavage , with examples including muscovite and stilbite . Resinous minerals have

1280-466: A high refractive index (of 1.9 or more). Minerals with a true adamantine lustre are uncommon, with examples including cerussite , zircon , and cubic zirconia . Minerals with a lesser (but still relatively high) degree of lustre are referred to as subadamantine , with some examples being garnet and corundum . Dull (or earthy ) minerals exhibit little to no lustre, due to coarse granulations which scatter light in all directions, approximating

1360-488: A lodestone adorned with a gilt coronet that was donated by Mary Cavendish in 1756, possibly to secure her husband's appointment as Chancellor of Oxford University. Isaac Newton 's signet ring reportedly contained a lodestone which was capable of lifting more than 200 times its own weight. And in 17th century London, the Royal Society displayed a 6-inch (15 cm) spherical lodestone (a terrella or 'little Earth'), which

1440-508: A memoir, but retorted that it was written for herself, not for delight, to give later generations a true account of her lineage and life. She noted that others, such as Caesar and Ovid , had done the same. She died in London, and was buried in Westminster Abbey on 7 January 1674. Her husband arranged for a monument, by the sculptor Grinling Gibbons , to be erected in the north transept of

1520-483: A negative reception to her books with their death. If the books suffer such a death (i. e. criticism), she requests silence and that they be forgotten, without alteration or inscriptions, and left undisturbed unless new merit is found. Again Cavendish sought to censor criticism and promote fame by instructing that only positive criticism should be voiced. In An Apology for Writing So Much upon This Book , she compares it to

1600-403: A number, including The Convent of Pleasure (1668) have been staged since. The Convent of Pleasure has recently become a staple of high school and university literature courses because of its feminism and Sapphic plot and character elements. Several of Cavendish's works have epistles, prefaces, prologues and epilogues in which she discusses her work, philosophy and ambition, while instructing

1680-484: A previous marriage, two of whom, Jane and Elizabeth , wrote a comic play, The Concealed Fancies . Cavendish later wrote a biography of her husband: The Life of the Thrice Noble, High and Puissant Prince William Cavendish. In her dedication, Cavendish recalls a time when rumours surrounded the authorship of her works: that her husband wrote them. Cavendish notes that her husband defended her from these, but admits to

1760-481: A prose piece consisting largely of speeches and letters. The collection concludes with her thoughts on her writing and an advertisement for one of her future publications. Cavendish concluded the collection by stating she was aware that she did not write elegantly and that her phrasing and placement of words could be criticised. She said she had difficulty creating rhymes that could communicate her intended meaning. In short, Cavendish stated that she strove for meaning at

1840-589: A surprisingly vibrant, ongoing conversation and observation of contemporary life. Throughout her work on natural philosophy, Margaret Cavendish defends the belief that all nature is composed of free, self-moving, rational matter. Eileen O'Neill provides an overview of Cavendish's natural philosophy and its critical reception in her introduction to Observations upon Experimental Philosophy . She describes Cavendish's natural philosophy as rejecting Aristotelianism and mechanical philosophy and favouring Stoic doctrines: while women rarely wrote about natural philosophy in

1920-576: A time at the court of the young King Louis XIV . She became the second wife of William Cavendish, 1st Duke of Newcastle-upon-Tyne in 1645. Her husband, then-marquess William Cavendish, 1st Duke of Newcastle , was a Royalist commander in Northern England during the First English Civil War and in 1644 went into self-imposed exile in France . Margaret accompanied him and remained abroad until

2000-433: A time when women writers were not encouraged and in terms of her subject choice. She instructed readers in how to read and respond to her poetry, most often by inviting praise from supporters and requesting silence from those unaffected by her work. Cavendish commonly used the epistles to admit and excuse potential weaknesses in her writing. They were directed at specific audiences and varied accordingly. Looking at several of

2080-635: A way to gain credibility and a marketable image that would undercut a socially improper public image. Cavendish wrote her autobiography in response to what people were saying of her in her lifetime. It relates Cavendish's lineage, social status, fortune, upbringing, education and marriage, describes her pastimes and manners, and offers an account of her personality and ambition, including thoughts on her bashfulness, contemplative nature and writing. She also shares her views on gender (appropriate behaviour and activity), politics (Parliamentarians v. Royalists) and class (proper behaviour of servants). The memoir details

2160-602: Is a collection of letters, written as if composed by real women. The organisation is similar to that of The World's Olio (1655). The topics are as varied as the forms and length of the letters. They cover marriage, war, politics, medicine, science, English and classical literature, and miscellaneous matters like gambling and religious extremism. Some letters seem to point to characters as actual people – Thomas Hobbes may appear in letter 173 and C. R. stand for King Charles II, – and some are addressed to real people with whom Cavendish often communicated, but most are fictional, leading to

2240-587: Is a disease. If so, Cavendish stated, many others, including Aristotle , Cicero , Homer and St Augustine , have suffered the same disease. It was an honour for someone of great ambition (as she often identified herself) to share the disease of such wise and eloquent men. In these, as in her other writings, she asserts that she writes for herself and that her writing is a harmless pastime when compared with those of many other women. She contradicts herself, however, by adding that she writes for delight, which she had denied in her previous work. Also somewhat contradictory

2320-406: Is a quest for glory, perfection and praise, which she states is not effeminate. Even while writing and pursuing fame she remained modest and honourable and does nothing to dishonour her family. Cavendish attributed her confidence, as a type of censor, to her belief that there is no evil, only innocence in her desire for fame. As to her writing without permission, Cavendish excuses herself by stating it

2400-484: Is easier to get a pardon after the fact than to obtain leave beforehand. She places writing over gossip, as a common and negative female activity. She credits her books as tangible examples of her contemplation and contrasts her self-proclaimed harmless ideas with wild ideas that might lead to indiscreet actions. Cavendish explored writing closet dramas in her exile. She became one of the best-known women playwrights through her interest in philosophical nature. This epistle

2480-445: Is followed by a response from Mistress Toppe, praising Cavendish and her skill in poetical fiction, moral instruction, philosophical opinion, dialogue, discourses and poetical romances. Cavendish included a prefatory letter to natural philosophers. She knew no language but English, and even her English was somewhat limited, since she was familiar only with "that which is most usually spoke." In other words, she downplayed her knowledge of

2560-414: Is her intention of continuing to write even if she has no readers, which belies her desire for fame. Ultimately, Cavendish excuses her criticism of and engagement with the theories of other natural philosophers as a necessary step in the search for truth. In her epistle to the reader, Cavendish writes that woman's wit may equal that of man, and women may be able to learn as easily as men. She argues that wit

2640-526: Is natural, whereas learning is artificial, and in her time, men have more chance of educating themselves than women. Cavendish remarks on her own experience reading philosophical works: many such works have challenged her understanding with their frequently difficult words and expressions. Thus Cavendish advises writers of philosophy to use language appropriate to less expert readers. She defends this by stating that philosophical terms should ease communication of thoughts. She believes that successful communication

2720-483: Is possible in all languages and accuses those who complicate communication (particularly English writers) of aiming for esteem from those who admire writing simply because they do not understand it, without considering that it may be nonsense. In her own work, Cavendish states, she chooses not to use difficult terms, although she adds that she understands such terms. Her stated reason is that she desires her work to be accessible to people regardless of their education. Her aim

2800-524: Is responsible for alexandrite's characteristic green to red colour change. Alexandrite from the Ural Mountains in Russia is green by daylight and red by incandescent light. Other varieties of alexandrite may be yellowish or pink in daylight and a columbine or raspberry red by incandescent light. The optimum or "ideal" colour change would be fine emerald green to fine purplish red, but this is rare. Iridescence

2880-427: Is the 'play' or 'fire' of rainbow-coloured light caused by very thin regular structures or layers beneath the surface of a gemstone. Similar to a thin film of oil on water, these layers interfere with the rays of reflected light, reinforcing some colours and cancelling others. Iridescence is seen at its best in precious opal . Schiller (German, literally "shimmer"), is the metallic iridescence originating from below

2960-432: Is the display of a star-shaped luminous area. It is seen in some sapphires and rubies , where it is caused by impurities of rutile . It can also occur in garnet , diopside and spinel . Aventurescence (or aventurization ) is a reflectance effect like that of glitter . It arises from minute, preferentially oriented mineral platelets within the material. These platelets are so numerous that they also influence

3040-495: Is the way light interacts with the surface of a crystal , rock , or mineral . The word traces its origins back to the Latin lux , meaning "light", and generally implies radiance, gloss, or brilliance. A range of terms are used to describe lustre, such as earthy , metallic , greasy , and silky . Similarly, the term vitreous (derived from the Latin for glass , vitrum ) refers to

3120-727: Is to communicate her ideas clearly. She requests that any errors that may be found in her work be overlooked and readers remain focused on her main ideas. Here, as in many epistles, she instructs readers on how to approach her work and requests them to read it fully and withhold criticism until they have done so. Cavendish's prose tale was published in 1666 and again in 1668, each time with Observations upon Experimental Philosophy . As many such as Silvia Bowerbank and Sara Mendelson have noted, this early version of science fiction critiques and explores such issues as science, gender and power. It also views relations between imagination and reason and philosophy and fiction. Cavendish writes herself into

3200-483: The Lunheng ( Balanced Inquiries ): "A lodestone attracts a needle." In the 2nd century BC, Chinese geomancers were experimenting with the magnetic properties of lodestone to make a "south-pointing spoon" for divination. When it is placed on a smooth bronze plate, the spoon would invariably rotate to a north–south axis. While this has been shown to work, archaeologists have yet to discover an actual spoon made of magnetite in

3280-560: The Stuart Restoration in 1660. Cavendish, as a poet, philosopher, writer of prose romances, essayist and playwright, published under her own name at a time when most women writers remained anonymous. Her topics included gender, power, manners, scientific method and philosophy. Her utopian romance The Blazing World is one of the earliest examples of science fiction . She was unusual in her time for publishing extensively in natural philosophy and early modern science, producing over

3360-526: The 17th century, Cavendish published six books on the subject. O'Neill points out that Cavendish herself was not formally educated in natural philosophy, though William Cavendish and his brother Charles shared an interest in the subject and supported her interest and study in the area. She may also have been influenced by social encounters with philosophers such as Thomas Hobbes. O'Neill believes Hobbes (who had instructed Charles in philosophy) had marked influence on Cavendish's natural philosophy, making her one of

3440-692: The 17th century, preferring a vitalist model. In May 1667, she became the first woman to attend a meeting at the Royal Society of London , criticising and engaging with members and philosophers such as Robert Boyle . She has been claimed as an early opponent of animal testing . Cavendish's publications brought her fame and helped to disprove the contemporary belief that women were inherently inferior to men. Cavendish used them to advocate women's education: women were capable of learning and benefiting from education, and she insisted her own works would have been better still if, like her brothers, she had been able to attend school. Cavendish's father, Thomas Lucas,

3520-468: The World abroad." It manifested itself in reluctance to discuss her work in public, but this she satirised in her writing. Cavendish defined and sought self-cures for the physical manifestations of her melancholia, which included "chill paleness", inability to speak, and erratic gestures. Cavendish's views on God and religion remained ambiguous. Her writings show her as a Christian, but she did not often address

3600-621: The abbey. The epitaph reads: "Her name was Margaret Lucas youngest daughter of Lord Lucas, earl of Colchester, a noble family, for all the brothers were valiant, and all the sisters virtuous". All the Brothers Were Valiant became the title of a novel and number of film adaptations in the early 20th century. Poems and Fancies encompasses poems, epistles and some prose on topics that include natural philosophy, atoms, nature personified, macro/microcosms, other worlds, death, battle, hunting, love, honour and fame. Her poems at times take

3680-675: The appearance of resin , chewing gum or (smooth-surfaced) plastic. A principal example is amber , which is a form of fossilized resin. Silky minerals have a parallel arrangement of extremely fine fibres, giving them a lustre reminiscent of silk . Examples include asbestos , ulexite and the satin spar variety of gypsum . A fibrous lustre is similar, but has a coarser texture. Submetallic minerals have similar lustre to metal, but are duller and less reflective. A submetallic lustre often occurs in near-opaque minerals with very high refractive indices, such as sphalerite , cinnabar , anthracite , and cuprite . Vitreous minerals have

3760-761: The book, which details a fictional, quite separate new world and its empress. She remarks in her epilogue that she is the empress, adding that in much the same way as there was a Charles the First, she would be seen as Margaret the First. Two volumes of Cavendish's dramatic works were printed. Plays (1662), printed by A. Warren (London) includes: Plays, Never Before Printed (1668) was published by Anne Maxwell (London): Cavendish also published collections of Philosophical Letters (1664), orations , as in her collection entitled Orations (1662). Many of her works address such issues as natural philosophy, gender, power and manners. Cavendish's plays were never acted in her lifetime, but

3840-405: The cause of women. In her epistle to Mistress Toppe, Cavendish states a desire for fame as her main reason for writing. Again she asks for acceptance of her writing as a digression from accepted gender norms. While she often brings in metaphors of domestic or stereotypical feminine activities, here she tries to excuse her desire for fame by distancing her ambition from what is feminine: her ambition

3920-772: The dwellings of the living, or the interments of the dead. Detailed analysis of the Olmec artifact revealed that the "bar" was composed of hematite with titanium lamellae of Fe 2–x Ti x O 3 that accounted for the anomalous remanent magnetism of the artifact. "A century of research has pushed back the first mention of the magnetic compass in Europe to Alexander Neckam about +1190, followed soon afterwards by Guyot de Provins in +1205 and Jacques de Vitry in +1269. All other European claims have been excluded by detailed study..." Lodestones have frequently been displayed as valuable or prestigious objects. The Ashmolean Museum in Oxford contains

4000-455: The earliest known references to lodestone's magnetic properties was made by 6th century BC Greek philosopher Thales of Miletus , whom the ancient Greeks credited with discovering lodestone's attraction to iron and other lodestones. The name magnet may come from lodestones found in Magnesia , Anatolia . The ancient Indian medical text Sushruta Samhita describes using magnetic properties of

4080-478: The effect may also occur in other minerals such as aquamarine , moonstone and tourmaline . Colour change is most commonly found in alexandrite, a variety of chrysoberyl gemstones. Other gems also occur in colour-change varieties, including (but not limited to) sapphire , garnet , spinel . Alexandrite displays a colour change dependent upon light, along with strong pleochroism . The gem results from small-scale replacement of aluminium by chromium oxide, which

4160-1043: The epistles in Poems and Fancies , her dedication to Sir Charles Cavendish, her brother in law, compares writing poetry to spinning and calls poetry mental spinning – it was commonly thought to be more appropriate for women to spin than to write, but she herself was better at writing. This is one of several occasions when Cavendish calls attention to stereotypical gender roles and expands on her reasons for not following them. As here, Cavendish often employed metaphors to describe her writing in terms of stereotypical feminine tasks or interests, such as spinning, fashion and motherhood. While criticising her own work, she said it would seem better if Sir Charles Cavendish looked favourably on it. Cavendish often appealed to readers for applause: if it were well received it would be somewhat improved. She ends by complimenting Charles's charity and generosity. In her epistle to noble and worthy ladies and in many others, Cavendish plainly expresses her desire for fame. She

4240-628: The existency of God, as, that he is to be adored and worshipped. And thus the inanimate part may, after its own manner, worship and adore God." Cavendish in her memoir explained her enjoyment in reinventing herself through fashion. She said she aimed at uniqueness in dress, thoughts and behaviour, and disliked wearing the same fashions as other women. She also made her desire for fame public. Several passages remark on her virtuous character: while acknowledging goodness in others, she thought it acceptable to hope to better them and even achieve everlasting fame. She expected to be criticised for deciding to write

4320-640: The expense of elegance, her aim being to communicate ideas. She also noted that she expected her work to be criticised for not being useful, but she wrote not to instruct her readers in the arts, sciences or divinity, but to pass her time, asserting that she made better use of her time than many others. Cavendish returned to these points in her epistles and poems. Cavendish, like authors such as Aphra Behn and William Wordsworth , stated her intended audience, writing purpose and philosophy in prefaces, prologues, epilogues and epistles. Her several epistle dedications for Poems and Fancies often sought to justify writing at

4400-971: The few 17th-century supporters of Hobbes' materialist philosophy, which argued that incorporeal souls did not exist in nature. Beginning in the 1660s, Cavendish began to study the work of her contemporaries more seriously. O'Neill suggests that such study was meant to enable Cavendish to argue her own points better by contrast with those of other natural philosophers. O'Neill notes that Cavendish's natural philosophy and her writing in general were criticised by many contemporaries and by more recent readers, such as Pepys , Henry More and Virginia Woolf . Cavendish's work has also received positive criticism and been lauded by many for tackling typically male-dominated subjects such as natural philosophy. Letters and poems of praise by her husband were included in several of her published works. Cavendish in her preface to Observations upon Experimental Philosophy states that she expects readers to say that her practice of writing prolifically

4480-593: The lives of her family, including a short account of her brother Charles Lucas , one of the best Civil War Cavalier cavalry commanders, executed by the Parliamentarians for treason in the Second English Civil War . She goes on to address the economic and personal hardships that she and her family faced from the war and their political allegiance, such as loss of estates and bereavements. Published in 1664 by William Wilson, CCXI Sociable Letters (1664)

4560-493: The lodestone to remove arrows embedded in a person's body. The earliest Chinese literary reference to magnetism occurs in the 4th-century BC Book of the Devil Valley Master ( Guiguzi ). In the chronicle Lüshi Chunqiu , from the 2nd century BC, it is explicitly stated that "the lodestone makes iron come or it attracts it." The earliest mention of a needle's attraction appears in a work composed between 20 and 100 AD,

4640-441: The lustre of glass . (The term is derived from the Latin for glass, vitrum .) This type of lustre is one of the most commonly seen, and occurs in transparent or translucent minerals with relatively low refractive indices. Common examples include calcite , quartz , topaz , beryl , tourmaline and fluorite , among others. Waxy minerals have a lustre resembling wax . Examples include jade and chalcedony . Asterism

4720-511: The material's body colour. In aventurine quartz , chrome-bearing fuchsite makes for a green stone and various iron oxides make for a red stone. Chatoyant minerals display luminous bands, which appear to move as the specimen is rotated. Such minerals are composed of parallel fibers (or contain fibrous voids or inclusions), which reflect light into a direction perpendicular to their orientation, thus forming narrow bands of light. The most famous examples are tiger's eye and cymophane , but

4800-836: The matter. In her Physical Opinions, she explicitly stated her belief in the existence of God – "Pray account me not an Atheist, but believe as I do in God Almighty," – but sought to split philosophy from theology and so avoid debating God's actions in many of her philosophical works. Her theological temerity was unusual at a time when much women's writing was built around religion. Although Cavendish acknowledged God's existence, she held "that natural reason cannot perceive or have an idea of an immaterial being." So "when we name God, we name an Inexpressible, and Incomprehensible Being." Still, she believed that all parts of nature have an innate knowledge of God's existence. Even inanimate matter, she argues, "also have an interior, fixt and innate knowledge of

4880-531: The most important and influential minds of her time. Born Margaret Lucas to Sir Thomas Lucas (1573–1625) and Elizabeth Leighton (died 1647), she was the youngest child of the family. She had four sisters and three brothers, the royalists Sir John Lucas , Sir Thomas Lucas and Sir Charles Lucas , who owned the manor of St John's Abbey, Colchester . As a teenager, she became an attendant on Queen Henrietta Maria and travelled with her into exile in France, living for

4960-399: The odd seems ridiculous. She requests that her work be judged by reason, not prejudice. She then excuses weaknesses in her poetry by stating that she writes only to escape melancholy thoughts and fill idle time. She employs a food/feasting metaphor: her poems are not ripe, but applause and praise will make them pass as a "general feast" to those of vulgar taste who take quantity over quality. As

5040-499: The poet's work and begs for praise. The poet states that self-love influences her judgement of her own poetry, which she finds she likes so much that she is moved to continue writing in hope of fame. She claims to write without thought of how her work would be received by critics. She then recalls how she was visited by Reason, who advised her to stop writing. Reason said her writing was a waste of time, that her work would not be well received and she should not have her work printed, so that

5120-462: The printer would not lose money. Reason also stated that there were already too many books and she should burn what she had written to spare the world from more. The poet noted her own angry response: she sent her book to press before she could be persuaded otherwise. In hindsight, however, she regretted doing so: she felt ashamed by her writing and told the reader to pity her and wipe away her tears with praise. In The Poetresses Petition , she compares

5200-486: The reader on how to read and respond to her writing. Her work has been alternately criticised and championed from its original publication to the present day. Cavendish was an unorthodox and daring intellectual who received positive and negative commentary from her contemporaries. Negative comments can be found by the Royal Society member Samuel Pepys who once wrote of her as "a mad, conceited, ridiculous woman" though he

5280-610: The reader to read her fancies (poems) slowly, paying heed to each word, for each is a fancy itself. She warns that if readers lose their place or skip lines, they will miss the meaning of the entire work. Cavendish followed some epistles with poems on how they came to be published and how they should be received. The proximity of the poems to the epistles and their similarity in subject and tone, suggests that they may be interpreted as Cavendish's own point of view. The poem The Poetresses (sic) hasty Resolution , like many of Cavendish's epistles, contains excuses for errors that may be found in

5360-488: The reader. The stories concern "the advantageous production of woman as spectacle" and "repeatedly [feminise] the aristocratic and chivalric trope (or figure) of the fair unknown." Cavendish published this autobiographical memoir as an addendum to Natures Pictures Drawn by Fancies Pencil to the Life , in 1656. She wrote it at the age of 33, which has been discussed by literary critics. One critic sees Cavendish's autobiography as

5440-448: The sale. In the event she received no benefit. She noted that while many women petitioned for funds, she herself only did so once, and being denied decided such efforts were not worth the trouble. After a year and a half she left England to be with her husband again. Cavendish stated in A True Relation of My Birth, Breeding, and Life that her bashful nature, which she described as " melancholia ", made her "repent my going from home to see

5520-609: The surface of a stone that occurs when light is reflected between layers of minerals. It is seen in moonstone and labradorite and is very similar to adularescence and aventurescence . Margaret Cavendish, Duchess of Newcastle-upon-Tyne Margaret Cavendish, Duchess of Newcastle-upon-Tyne ( née  Lucas ; 1623 – 16 December 1673) was a prolific English philosopher, poet, scientist, fiction writer and playwright. She produced more than 12 original literary works, many of which became well known due to her high social status, which allowed Margaret to meet and converse with some of

5600-430: The technical vocabulary used by natural philosophers, and thereby her knowledge of opinions and discourses that preceded her own. She then dismissed errors she might make as trivial, asserting that she did not mean her text to be taken as truth. She wrote simply to pass time and expected her work to be read for the same end. This epistle also explained her writing in verse: poets were thought to write fiction and that fiction

5680-653: Was aligned with pastime, not truth. So verse might be expected to contain errors. Cavendish lamented that her work was not more entertaining and advised readers to skip any part they did not like. Her epistle states that with no children and at that time no estate, she has a lot of spare time, which she fills by writing, not housekeeping. Food husbandry in poetry was well-ordered fancy composed of fine language, proper phrases and significant words. Cavendish excused errors that might be found in her work as due to youth and inexperience, for she wrote only to distract herself from hardships of her husband's and her own. Comparing her book to

5760-504: Was also the first woman to be invited to attend a session of the Royal Society. One member, John Evelyn , saw in Cavendish "a mighty pretender to learning, poetry, and philosophy". Yet her knowledge was recognised by some, such as the protofeminist Bathsua Makin : "The present Dutchess of New-Castle, by her own Genius, rather than any timely Instruction, over-tops many grave Gown-Men." She saw her exemplifying what women could become through education. New manuscript evidence also suggests she

5840-590: Was eager to read her work. Dorothy Osborne reflected in one published letter, after reading a book by the Duchess, that she was "sure there are soberer people in Bedlam." She also had numerous admirers, Constantijn Huygens , Mildmay Fane , Earl of Westmorland, John Dryden , Kenelm Digby , Henry More were among them. Joseph Glanvill and Walter Charleton corresponded with her and engaged with philosophy and science. After her death, her husband William Cavendish compiled

5920-468: Was exiled after a duel that led to the death of "one Mr. Brooks", but pardoned by King James. He returned to England in 1603. As the youngest of eight, Cavendish recorded spending a lot of time with her siblings. She had no formal education, but had access to libraries and tutors, although she hinted that the children paid little heed to tutors, who were "rather for formality than benefit". Cavendish began putting ideas down on paper at an early age, although it

6000-533: Was in Oxford, Cavendish never gained permission from her mother to become a lady-in-waiting. She accompanied the Queen into exile in France, away from her family for the first time. She notes that while she was confident in the company of her siblings, amongst strangers she became bashful, being afraid she might speak or act inappropriately without her siblings' guidance, while anxious to be well received and well liked. She spoke only when necessary and so came to be regarded as

6080-633: Was not concerned that the best people should like her writing, as long as many people did. She justified this by linking fame to noise and noise to great numbers of people. Cavendish often assumed a defensive position, here justified by asserting that she expected critiques from males and females not only of her writing, but of her practice of writing itself. Cavendish argued that women who busy themselves writing will not act ineptly or gossip. Though she expected criticism from females, she calls for female support in gaining honour and reputation. She ends by stating that if she fails, she will see herself as martyred for

6160-432: Was poorly accepted for women to display such intelligence at the time and she kept her efforts in the privacy of her home. The family had significant means and Cavendish stated that her widowed mother chose to keep her family in a condition "not much lower" than when her father was alive; the children had access to "honest pleasures and harmless delights". Her mother had little to no male help. When Queen Henrietta Maria

6240-418: Was the only man she was ever in love with, not for his title, wealth or power, but for merit, justice, gratitude, duty and fidelity. She saw these as attributes that held people together even in misfortune, and in their case helped them to endure suffering for their political allegiance. Cavendish had no children, despite efforts by her physician to help her conceive. Her husband had five surviving children from

6320-785: Was typical in her writing, applause is welcomed and criticism censored, as she advises those who dislike her poetry to keep silent. Hers are poems of fancy and so require study. She recommends that as one with a troubled conscience ought to look to a minister for guidance. Likewise a reader will ask a poet for help in understanding her poems. Attempting again to guide readers to a positive reception of her book, Cavendish distinguishes poets (able judges of poetry) from rhymers (faulty judges of poetry) and advises people not to call her book nonsense or poorly constructed out of their own ignorance and malice. Returning again to her desire for fame, Cavendish notes that if judged by an honest poet, who would not be envious, her work would receive applause. Cavendish asks

6400-595: Was used to illustrate the Earth's magnetic fields and the function of mariners' compasses. One contemporary writer, the satirist Ned Ward , noted how the terrella "made a paper of Steel Filings prick up themselves one upon the back of another, that they stood pointing like the Bristles of a Hedge-Hog ; and gave such Life and Merriment to a Parcel of Needles, that they danc'd [...] as if the devil were in them."
