first edition 1528 of the first Latin translation from the original Greek version.THE FIRST PUBLISHED LATIN TRANSLATION made from the original Greek text of Ptolemy's most important astronomical and mathematical work. "Until the innovative work of Tycho Brahe and Kepler in the late sixteenth and early seventeenth centuries, that is, for nearly fifteen hundred, years, the Almagest was the basis of all sophisticated astronomy, a longevity exceeded only by Euclid's Elements" (Swerdlow). Instruments mentioned or described include the equatorial armillary, the plinth, the meridional armillary, the triquestrum and the armillary astrolabon. The Almagest had been translated into Arabic and was known to the later Middle Ages in a Latin translation from the Arabic by Gerard of Cremona; that version was first published in Venice in 1515.
