Callicrates or Kallikrates (Greek: Καλλικράτης), was a fleet commander (nauarchos) of the Ptolemaic navy, who served under Ptolemy II Philadelphus during the Second Syrian War from 270 to 250 BC.
[2] He was commander of the Ptolemaic Aegean Fleet and was engaged in naval operations during the Second Syrian War (260–253 BC) where he suffered successive defeats against the allied forces of Antiochus II Theos of the Seleucid Empire and Antigonus II Gonatas of the Kingdom of Macedon.
[3] During the lifetime of Arsinoe II the sibling monarchs and Callicrates received a tribute from his home island of Samos.
[4] Around the year 257 BC he was instructed to build a temple to Isis and Anubis at Canopus on behalf of Ptolemy II.
As a "benefactor" of the city of Olous in Crete he received honorary citizenship (proxenia); he had probably been there on a diplomatic mission with about eight men about the time of the Chremonidean War.
