Sosicrates of Rhodes (Greek: Σωσικράτης ὁ Ῥόδιος; floruit c. 180 BC) was a Greek historical writer. He was born on the island Rhodes and is noted, chiefly, for his frequent mention by Diogenes Laërtius in his Lives and Opinions of Eminent Philosophers,^[1] referencing Sosicrates as the sole authority behind such facts as Aristippus having written nothing.^[2] It is inferred that Sosicrates flourished after Hermippus and before Apollodorus of Athens, and, therefore, sometime between 200 and 128 BC. Sosicrates is claimed to have penned a Successions of Philosophers, quoted by both Athenaeus^[3] and Diogenes Laërtius.^[4] Sosicrates also composed a work on the history of Crete,^[5] though neither of the aforementioned works have survived.
