In ancient Greece, Echecrates () was the name of the following men: Echecrates of Thessaly, a military officer of Ptolemy IV Philopator, documented around 219–217 BC. A son of Demetrius the Fair (c. 285–250 BC) by Olympias of Larissa, and brother of Antigonus III Doson. He had a son named Antigonus after his uncle. Three Pythagorean philosophers mentioned by Iamblichus: A Locrian, one of those to whom Plato is said to have gone for instruction. The name Caetus in Valerius Maximus is perhaps an erroneous reading for Echecrates. A Tarentine, probably the same who is mentioned in Plato's Ninth Letter. Echecrates of Phlius, a contemporary with Aristoxenus the Peripatetic. References Ancient Greeks
