The Book Of Curiosities
The ''Book of Curiosities'' (Arabic: ''Kitāb Gharā’ib al-funūn wa-mulaḥ al-ʿuyūn'', literally translated as ''Book of Curiosities of the Sciences and Marvels for the Eyes'') is an anonymous 11th-century Arabic cosmography from Fatimid Egypt containing a series of early illustrated maps of the world and celestial diagrams of the universe and sky. ''The'' ''Book of Curiosities'' contains 17 maps in total, 14 of which are extremely rare not only in Islamic cartography but also in greater medieval map history. The cosmography includes the earliest recorded map of Sicily as well as a rectangular world map, considered the earliest surviving map with a graphic scale. The autograph manuscript has not survived, but the Bodleian Library of Oxford University acquired one of the only known copies of the manuscript in 2002, making its contents widely accessible today due to its digitization. Based on the production processes and physical materials of the copy, such as paper and pig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Book Of Curiosities - Sicily Map
A book is a medium for recording information in the form of writing or images, typically composed of many pages (made of papyrus, parchment, vellum, or paper) bound together and protected by a cover. The technical term for this physical arrangement is '' codex'' (plural, ''codices''). In the history of hand-held physical supports for extended written compositions or records, the codex replaces its predecessor, the scroll. A single sheet in a codex is a leaf and each side of a leaf is a page. As an intellectual object, a book is prototypically a composition of such great length that it takes a considerable investment of time to compose and still considered as an investment of time to read. In a restricted sense, a book is a self-sufficient section or part of a longer composition, a usage reflecting that, in antiquity, long works had to be written on several scrolls and each scroll had to be identified by the book it contained. Each part of Aristotle's ''Physics'' is called ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Star Lore
Star lore or starlore is the creating and cherishing of mythical stories about the stars and star patterns (constellations and asterisms); that is, folklore based upon the stars and star patterns. Using the stars to explain religious doctrines or actual events in history is also defined as star lore. Star lore has a very long history; it has been practiced by nearly every culture recorded in history, dating as far back as 5,500 years ago. It was practiced by prehistoric cultures of the Paleolithic and Neolithic periods as well. Orion and Scorpius One example of star lore is the inventing of the story of Orion the Hunter and the Scorpius the Scorpion by the ancient Greeks. This ancient culture saw a very startling pattern of bright stars in the winter sky that, from their point of view, resembled a mighty hunter, which they named Orion. During the summer, they saw another startling pattern of bright stars that resembled a scorpion. They noticed that the constellations of Orion ...

Geographic Coordinate System
The geographic coordinate system (GCS) is a spherical or ellipsoidal coordinate system for measuring and communicating positions directly on the Earth as latitude and longitude. It is the simplest, oldest and most widely used of the various spatial reference systems that are in use, and forms the basis for most others. Although latitude and longitude form a coordinate tuple like a cartesian coordinate system, the geographic coordinate system is not cartesian because the measurements are angles and are not on a planar surface. A full GCS specification, such as those listed in the EPSG and ISO 19111 standards, also includes a choice of geodetic datum (including an Earth ellipsoid), as different datums will yield different latitude and longitude values for the same location. History The invention of a geographic coordinate system is generally credited to Eratosthenes of Cyrene, who composed his now-lost ''Geography'' at the Library of Alexandria in the 3rd century ...

Muhammad Ibn Musa Al-Khwarizmi
Muḥammad ibn Mūsā al-Khwārizmī ( ar, محمد بن موسى الخوارزمي, Muḥammad ibn Musā al-Khwārazmi; ), or al-Khwarizmi, was a Persians, Persian polymath from Khwarazm, who produced vastly influential works in Mathematics in medieval Islam, mathematics, Astronomy in the medieval Islamic world, astronomy, and Geography and cartography in medieval Islam, geography. Around 820 CE, he was appointed as the astronomer and head of the library of the House of Wisdom in Baghdad.Maher, P. (1998), "From Al-Jabr to Algebra", ''Mathematics in School'', 27(4), 14–15. Al-Khwarizmi's popularizing treatise on algebra (''The Compendious Book on Calculation by Completion and Balancing'', c. 813–833 CEOaks, J. (2009), "Polynomials and Equations in Arabic Algebra", ''Archive for History of Exact Sciences'', 63(2), 169–203.) presented the first systematic solution of linear equation, linear and quadratic equations.

Naskh (script)
Naskh ( ar, , qalam an-naskh, from the verb , , 'to copy', from n-s-kh root (ن-س-خ)) is a smaller, round script of Islamic calligraphy. Naskh is one of the first scripts of Islamic calligraphy to develop, commonly used in writing administrative documents and for transcribing books, including the Qur’an, because of its easy legibility. In his 1617 ''Grammatica Arabica'', Thomas van Erpe defined naskhī characters as the "noblest and true writing style". Origin Naskh style of writing can be found as early as within the first century of the Islamic calendar. Round scripts became the most popular in the eleventh, twelfth and thirteenth centuries, due to their use by scribes. Ibn Muqla is credited with standardizing the "Six Pens" of Islamic calligraphy, also including , , , , and . These are known as "the proportioned scripts" () or "the six scripts" (). Kufic is commonly believed to predate naskh, but historians have traced the two scripts as coexisting long before their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Papermaking
Papermaking is the manufacture of paper and cardboard, which are used widely for printing, writing, and packaging, among many other purposes. Today almost all paper is made using industrial machinery, while handmade paper survives as a specialized craft and a medium for artistic expression. In papermaking, a dilute suspension consisting mostly of separate cellulose fibres in water is drained through a sieve-like screen, so that a mat of randomly interwoven fibres is laid down. Water is further removed from this sheet by pressing, sometimes aided by suction or vacuum, or heating. Once dry, a generally flat, uniform and strong sheet of paper is achieved. Before the invention and current widespread adoption of automated machinery, all paper was made by hand, formed or laid one sheet at a time by specialized laborers. Even today those who make paper by hand use tools and technologies quite similar to those existing hundreds of years ago, as originally developed in China and other ...

Watermark
A watermark is an identifying image or pattern in paper that appears as various shades of lightness/darkness when viewed by transmitted light (or when viewed by reflected light, atop a dark background), caused by thickness or density variations in the paper. Watermarks have been used on postage stamps, currency, and other government documents to discourage counterfeiting. There are two main ways of producing watermarks in paper; the ''dandy roll process'', and the more complex ''cylinder mould process''. Watermarks vary greatly in their visibility; while some are obvious on casual inspection, others require some study to pick out. Various aids have been developed, such as ''watermark fluid'' that wets the paper without damaging it. A watermark is very useful in the examination of paper because it can be used for dating documents and artworks, identifying sizes, mill trademarks and locations, and determining the quality of a sheet of paper. The word is also used for digital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Folio
The term "folio" (), has three interconnected but distinct meanings in the world of books and printing: first, it is a term for a common method of arranging sheets of paper into book form, folding the sheet only once, and a term for a book made in this way; second, it is a general term for a sheet, leaf or page in (especially) manuscripts and old books; and third, it is an approximate term for the size of a book, and for a book of this size. First, a folio (abbreviated fo or 2o) is a book or pamphlet made up of one or more full sheets of paper, on each of which four pages of text are printed, two on each side; each sheet is then folded once to produce two leaves. Each leaf of a folio book thus is one half the size of the original sheet. Ordinarily, additional printed folio sheets would be inserted inside one another to form a group or "gathering" of leaves prior to binding the book. Second, folio is used in terms of page numbering for some books and most manuscripts that ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geography (Ptolemy)
The ''Geography'' ( grc-gre, Γεωγραφικὴ Ὑφήγησις, ''Geōgraphikḕ Hyphḗgēsis'', "Geographical Guidance"), also known by its Latin names as the ' and the ', is a gazetteer, an atlas, and a treatise on cartography, compiling the geographical knowledge of the 2nd-century Roman Empire. Originally written by Claudius Ptolemy in Greek at Alexandria around AD 150, the work was a revision of a now-lost atlas by Marinus of Tyre using additional Roman and Persian gazetteers and new principles. Its translation into Arabic in the 9th century and Latin in 1406 was highly influential on the geographical knowledge and cartographic traditions of the medieval Caliphate and Renaissance Europe. Manuscripts Versions of Ptolemy's work in antiquity were probably proper atlases with attached maps, although some scholars believe that the references to maps in the text were later additions. No Greek manuscript of the ''Geography'' survives from earlier than the 13th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
