Nomenclature

Cleostratus (ca. 520 BC; possibly 548 BC to 432 BC) was an astronomer of ancient Greece. He is believed by some scholars to have introduced the zodiac (beginning with Aries and Sagittarius) and the solar calendar to Greece from Babylonia.
The valley west-southwest of Cleostratus is unofficially called Vallis Cleostratus by D.Caes.
