Kâtip Çelebi, Mustafa bin Abdullah, Haji Khalifa or Kalfa, (1609, Istanbul – 1657 Istanbul)
Kâtip Celebi was an Ottoman scholar. A historian and geographer, he is regarded as one of the most productive authors of non-religious scientific literature in the 17th century Ottoman Empire. Among his best-known works is the Kashf al-?un?n ‘an as?m? al-kutub wa-al-fun?n, ('The Removal of Doubt from the Names of Books and the Arts'), a bibliographic encyclopaedia, written in Arabic, which lists more than 14,500 books in alphabetic order.
Life and works
The son of a soldier, he himself was a soldier for ten years until a heritage made him turn to a more contemplative life. As the accountant of the commissariat department of the Ottoman Army in Anatolia, he accompanied the Ottoman army in the campaign against Baghdad in 1625, was present at the siege of Erzurum, and returned to Istanbul in 1628. In the following year he was again in Baghdad and Hamadan, and in 1633-34 at Aleppo, whence he made the pilgrimage to Mecca (hence his title Hajji). The following year he was in Erivan and then returned to Consta...

Cihannüma (The mirror of the world) Constantinople, Ibrahim Müteferrika, 1732. First edition.
This is the second work by Kâtip Celebi published in 1729. The author was a well known writer on history and geography and a bibliophile and in this work intended to publish a universal system of geography. In fact only part of the work (including the description of Asia Minor) was completed by Kâtip who used European and Arabic and Persian sources, and the whole was supplemented and edited by Ibrahim, who dedicated it to the grand vizir of Sultan Mahmud II, Ali Pasha.
The picture is showing the map of the Indian Ocean and the China Sea that was engraved in 1728 by the Hungarian-born Ottoman cartographer and publisher Ibrahim Müteferrika; it is one of a series that illustrated Katip Çelebi’s Cihannuma (Universal Geography), the first printed book of maps and drawings to appear in the Islamic world.

Cassini de Thury, César-François
Biografiska uppgifter:17 June 1714 – 4 September 1784
César-François Cassini de Thury (17 June 1714 – 4 September 1784), also called Cassini III or Cassini de Thury, was a French astronomer and cartographer.
Cassini de Thury was born in Thury-sous-Clermont (Oise), the second son of Jacques Cassini and Suzanne Françoise Charpentier de Charmois. He was a grandson of Giovanni Domenico Cassini, and would become the father of Jean-Dominique Cassini, Comte de Cassini.
In 1735, he became a member of the French Academy of Sciences as a supernumerary adjunct astronomer, in 1741 as an adjunct astronomer, and in 1745 as a full member astronomer.
In January, 1751 he was elected a Fellow of the Royal Society.
He succeeded to his father’s official position in 1756 and continued the hereditary surveying operations. In 1744, he began the construction of a great topographical map of France, one of the landmarks in the history of cartography. Completed by his son Jean-Dominique, Cassini IV and published by the Académie des Sciences from 1744 to 1793, its 180 plates are known as the Cassini map(fr).
The post of director of the Paris observatory was created for his benefit in 1771 when the establishment ceased to be a dependency of the French Academy of Sciences.
His chief works are: La méridienne de l’Observatoire Royal de Paris (1744), a correction of the Paris meridian; Description géométrique de la terre (1775); and Description géométrique de la France (1784), which was completed by his son ('Cassini IV').
César-François Cassini de Thury died of smallpox in Paris on 4 September 1784,
The Cassini projection is a map projection described by César-François Cassini de Thury in 1745. It is the transverse aspect of theequirectangular projection, in that the globe is first rotated so the central meridian becomes the 'equator', and then the normal equirectangular projection is applied.
In practice, the projection has always been applied to models of the earth as an ellipsoid, which greatly complicates the mathematical development but is suitable for surveying. Nevertheless the use of the Cassini projection has largely been superseded by the Transverse Mercator projection, at least with central mapping agencies.
Areas along the central meridian, and at right angles to it, are not distorted. Elsewhere, the distortion is largely in a north-south direction, and varies by the square of the distance from the central meridian. As such, the greater the longitudinal extent of the area, the worse the distortion becomes.
Due to this, the Cassini projection works best on long, narrow areas, and worst on wide areas.
