Almagest

Almagest is the Latin form of the Arabic name (al-kitabu-l-mijisti, i.e. "The Great Book") of a mathematical and astronomical treatise proposing the complex motions of the stars and planetary paths, originally written in Greek as μαθηματικἠ σύνταξις (Mathematike Syntaxis, "Mathematical Treatise"; later titled Hè Megalè Syntaxis, "The Great Treatise") by Ptolemy of Alexandria, Egypt. The date of Almagest has recently been more precisely established. Ptolemy set up a public inscription at Canopus in Egypt in 147/148 A.D. The late N. T. Hamilton found that the version of Ptolemy's models set out in the Canopic Inscription was earlier than the version in Almagest. Hence Almagest cannot have been completed before about A.D. 150, a quarter century after Ptolemy began observing.[1]  Its geocentric model was accepted as correct for over a thousand years in Arab and European societies. The Almagest is our most important source of information on ancient Greek astronomy. The Almagest has also been valuable to students of mathematics because it provides information on the ancient Greek mathematician Hipparchus' work, which has been lost. Hipparchus wrote about trigonometry, but since his works have been lost mathematicians use Ptolemy's book as their source for information on Hipparchus' works and ancient Greek trigonometry in general.

Almagest – dzieło  Klaudiusza Ptolemeusza napisane ok. roku 140, zawierające kompendium ówczesnej wiedzy astronomicznej, matematyczny wykład astronomii geocentrycznej. Autor opierał się głównie na dziełach Hipparcha i obserwacjach astronomów babilońskich i aleksandryjskich. Dzieło zawiera m.in. traktat o trygonometrii płaskiej i sferycznej, teorie ruchów Słońca, Księżyca i planet, katalog gwiazd.

Almagesto è il nome, derivato dall'arabo al-Magisṭī, adattamento della parola greca , "Megíste", con cui è generalmente indicata l'importante opera astronomica scritta intorno al 150 da Claudio Tolomeo (in arabo chiamato Baṭlamiyūs), il cui titolo originario in greco era "Mathematiké Sýntaxis" ("Trattato matematico") o "Megále Sýntaxis" ("Grande Trattato"). Per più di mille anni essa costituì la base delle conoscenze astronomiche nel mondo islamico e in Europa.
