Lapidary (text)
A lapidary is a text in verse or prose, often a whole book, that describes the physical properties and virtues of precious and semi-precious stones, that is to say, a work on gemology. It was frequently used as a medical textbook since it also comprises practical information about each stone's medical application. Several lapidaries also provide information about countries or regions where some rocks were thought to originate, and others speculate about the natural forces in control of their formation. Lapidaries were very popular in the Middle Ages when belief in gems' inherent power for various purposes was widely held. Among the wealthy, collecting jewels was often an obsession and a popular way to store and transport capital. In the Middle Ages, scholars often distinguish "three different kinds of lapidaries: 1. the scientific lapidary 2. the magical or astrological lapidary that sets the relationship between the Signs of the zodiac and a particular gemstone and 3. the Christian ...

Jean D'Outremeuse
Jean d'Outremeuse or ''Jean des Preis'' (1338 in Liège – 1400) was a writer and historian who wrote two romanticised historical works and a lapidary (text), lapidary. ''La Geste de Liége'' is an account of the mythical history of his native city, Liège, written partly in prose and partly in verse. It was probably based on an existing text and consists of three books: book one, in 40,000 lines, book two, in 12,224 lines with prose summaries, book three, has been lost, but a few passages have been found. ''Ly Myreur des Histors'' ("The Mirror of Histories") is a more ambitious narrative, purporting to be a history of the world from the flood up to the 14th century. It combines Vincent de Beauvais's early works ''Ogier le Danois'' and the ''Geste de Liège'' into a universal history, from the fall of Troy to 1340, mixing real and legendary events. The Liège herald, Louis Abry (1643–1720), refers to the lost fourth book of the ''Myreur des Hystors'' of Johans des Preis, sty ...

Sapphire
Sapphire is a precious gemstone, a variety of the mineral corundum, consisting of aluminium oxide () with trace amounts of elements such as iron, titanium, chromium, vanadium, or magnesium. The name sapphire is derived via the Latin "sapphirus" from the Greek "sappheiros", which referred to Lapis lazuli, lapis lazuli. It is typically blue, but natural "fancy" sapphires also occur in yellow, purple, orange, and green colors; "parti sapphires" show two or more colors. Red corundum stones also occur, but are called ruby, rubies rather than sapphires. Pink-colored corundum may be classified either as ruby or sapphire depending on locale. Commonly, natural sapphires are cut and polished into gemstones and worn in jewellery, jewelry. They also may be created synthetically in laboratories for industrial or decorative purposes in large boule (crystal), crystal boules. Because of the remarkable hardness of sapphires 9 on the Mohs scale of mineral hardness, Mohs scale (the third hardest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emerald
Emerald is a gemstone and a variety of the mineral beryl (Be3Al2(SiO3)6) colored green by trace amounts of chromium or sometimes vanadium.Hurlbut, Cornelius S. Jr. and Kammerling, Robert C. (1991) ''Gemology'', John Wiley & Sons, New York, p. 203, . Beryl has a hardness of 7.5–8 on the Mohs scale. Most emeralds are highly included, so their toughness (resistance to breakage) is classified as generally poor. Emerald is a cyclosilicate. Etymology The word "emerald" is derived (via fro, esmeraude and enm, emeraude), from Vulgar Latin: ''esmaralda''/''esmaraldus'', a variant of Latin ''smaragdus'', which was a via grc, σμάραγδος (smáragdos; "green gem") from a Semitic language. According to Webster's Dictionary the term emerald was first used in the 14th century. Properties determining value Emeralds, like all colored gemstones, are graded using four basic parameters–the four ''C''s of connoisseurship: ''color'', ''clarity,'' ''cut'' and ''carat weight''.

Diamond (gemstone)
Diamond ''adámas'', meaning "unbreakable", "proper", or "unalterable" is one of the best-known and most sought-after gemstones. They have been used as decorative items since ancient times. The hardness of diamond and its high dispersion of light — giving the diamond its characteristic "fire" — make it useful for industrial applications and desirable as jewelry. Diamonds are such a highly traded commodity that multiple organizations have been created for grading and certifying them based on the "four Cs", which are color, cut, clarity, and carat. Other characteristics, such as presence or lack of fluorescence, also affect the desirability and thus the value of a diamond used for jewelry. Diamonds are used in engagement rings. The practice is documented among European aristocracy as early as the 15th century, though ruby and sapphire were more desirable gemstones. The modern popularity of diamonds was largely created by De Beers Consolidated Mines, which established the fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irish Language
Irish ( Standard Irish: ), also known as Gaelic, is a Goidelic language of the Insular Celtic branch of the Celtic language family, which is a part of the Indo-European language family. Irish is indigenous to the island of Ireland and was the population's first language until the 19th century, when English gradually became dominant, particularly in the last decades of the century. Irish is still spoken as a first language in a small number of areas of certain counties such as Cork, Donegal, Galway, and Kerry, as well as smaller areas of counties Mayo, Meath, and Waterford. It is also spoken by a larger group of habitual but non-traditional speakers, mostly in urban areas where the majority are second-language speakers. Daily users in Ireland outside the education system number around 73,000 (1.5%), and the total number of persons (aged 3 and over) who claimed they could speak Irish in April 2016 was 1,761,420, representing 39.8% of respondents.

Hebrew Language
Hebrew (; ; ) is a Northwest Semitic language of the Afroasiatic language family. Historically, it is one of the spoken languages of the Israelites and their longest-surviving descendants, the Jews and Samaritans. It was largely preserved throughout history as the main liturgical language of Judaism (since the Second Temple period) and Samaritanism. Hebrew is the only Canaanite language still spoken today, and serves as the only truly successful example of a dead language that has been revived. It is also one of only two Northwest Semitic languages still in use, with the other being Aramaic. The earliest examples of written Paleo-Hebrew date back to the 10th century BCE. Nearly all of the Hebrew Bible is written in Biblical Hebrew, with much of its present form in the dialect that scholars believe flourished around the 6th century BCE, during the time of the Babylonian captivity. For this reason, Hebrew has been referred to by Jews as '' Lashon Hakodesh'' (, ) since an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albertus Magnus
Albertus Magnus (c. 1200 – 15 November 1280), also known as Saint Albert the Great or Albert of Cologne, was a German Dominican friar, philosopher, scientist, and bishop. Later canonised as a Catholic saint, he was known during his lifetime as ''Doctor universalis'' and ''Doctor expertus'' and, late in his life, the sobriquet ''Magnus'' was appended to his name. Scholars such as James A. Weisheipl and Joachim R. Söder have referred to him as the greatest German philosopher and theologian of the Middle Ages. The Catholic Church distinguishes him as one of the 37 Doctors of the Church. Biography It seems likely that Albert was born sometime before 1200, given well-attested evidence that he was aged over 80 on his death in 1280. Two later sources say that Albert was about 87 on his death, which has led 1193 to be commonly given as the date of Albert's birth, but this information does not have enough evidence to be confirmed. Albert was probably born in Lauingen (now in Bav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vincent Of Beauvais
Vincent of Beauvais ( la, Vincentius Bellovacensis or ''Vincentius Burgundus''; c. 1264) was a Dominican friar at the Cistercian monastery of Royaumont Abbey, France. He is known mostly for his ''Speculum Maius'' (''Great mirror''), a major work of compilation that was widely read in the Middle Ages. Often retroactively described as an encyclopedia or as a ''florilegium'', his text exists as a core example of brief compendiums produced in medieval Europe. Biography The exact dates of his birth and death are unknown, and not much detail has surfaced concerning his career. Conjectures place him first in the house of the Dominicans at Paris between 1215 and 1220, and later at the Dominican monastery founded by Louis IX of France at Beauvais in Picardy. It is more certain, however, that he held the post of "reader" at the monastery of Royaumont on the Oise, not far from Paris, also founded by Louis IX, between 1228 and 1235. Around the late 1230s, Vincent had begun working on the '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marbode Of Rennes
Marbodus, Marbod or Marbode of Rennes ( 1035 – 11 September 1123) was archdeacon and schoolmaster at Angers, France, then Bishop of Rennes in Brittany. He was a respected poet, hagiographer, and hymnologist. Biography Marbod was born near Angers in Anjou, France, presumably in the mid-1030s. He received at least part of his early education at Angers under archdeacon and schoolmaster Rainaldus (d. c. 1076), who may have been trained by Fulbert of Chartres. He was a well-known and highly praised scholar in Angers. Marbod had three known named relatives: a brother named Hugo, who was a canon of Saint-Maurice of Angers, a mother most likely named Hildeburgis, and a nephew named Herveus. Two of Marbod's family members were in the entourage of Count Fulk le Réchin of Anjou. The power of the episcopate in Northern France during the twelfth century was immense. The position came with land, economic, political, and spiritual power which had been continued on from the time of Carolingi ...

Avicenna
Ibn Sina ( fa, ابن سینا; 980 – June 1037 CE), commonly known in the West as Avicenna (), was a Persian polymath who is regarded as one of the most significant physicians, astronomers, philosophers, and writers of the Islamic Golden Age, and the father of early modern medicine. Sajjad H. Rizvi has called Avicenna "arguably the most influential philosopher of the pre-modern era". He was a Muslim Peripatetic philosopher influenced by Greek Aristotelian philosophy. Of the 450 works he is believed to have written, around 240 have survived, including 150 on philosophy and 40 on medicine. His most famous works are ''The Book of Healing'', a philosophical and scientific encyclopedia, and ''The Canon of Medicine'', a medical encyclopedia which became a standard medical text at many medieval universities and remained in use as late as 1650. Besides philosophy and medicine, Avicenna's corpus includes writings on astronomy, alchemy, geography and geology, psychology, I ...

Isidore Of Seville
Isidore of Seville ( la, Isidorus Hispalensis; c. 560 – 4 April 636) was a Spanish scholar, theologian, and archbishop of Seville. He is widely regarded, in the words of 19th-century historian Montalembert, as "the last scholar of the ancient world". At a time of disintegration of classical culture, aristocratic violence and widespread illiteracy, Isidore was involved in the conversion of the Arian Visigothic kings to Catholicism, both assisting his brother Leander of Seville and continuing after his brother's death. He was influential in the inner circle of Sisebut, Visigothic king of Hispania. Like Leander, he played a prominent role in the Councils of Toledo and Seville. His fame after his death was based on his ''Etymologiae'', an etymological encyclopedia that assembled extracts of many books from classical antiquity that would have otherwise been lost. This work also helped standardize the use of the period ( full stop), comma, and colon. Since the early ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
