Timaeus of Tauromenium (Ancient Greek: Τιμαῖος; born 356 or 350 BC; died c. 260 BC) was an ancient Greek historian. He was widely regarded by ancient authors as the most influential historian between the time of Ephorus (4th century BC) and Polybius (2nd century BC).[1][2][3] In the words of scholar Lionel I. C. Pearson, Timaeus "maintained his position as the standard authority on the history of the Greek West for nearly five centuries."[4]
