Kidinnu
400 BC - 330 BC

Kidinnu
Kidinnu (also Kidunnu; possibly fl. 4th century BC; possibly died 14 August 330 BC) was a Chaldean astronomer and mathematician. Strabo of Amaseia called him Kidenas, Pliny the Elder called him Cidenas, and Vettius Valens called him Kidynas. Some cuneiform and classical Greek and Latin texts mention an astronomer with this name, but it is not clear if they all refer to the same individual: The Greek geographer Strabo of Amaseia, in Geography 16.1.6, writes: "In Babylon a settlement is set apart for the local philosophers, the Chaldeans, as they are called, who are concerned mostly with astronomy; but some of these, who are not approved of by the others, profess to be writers of horoscopes.
