Sosicrates of Rhodes (Greek: Σωσικράτης ὁ Ῥόδιος; floruit c. 180 BC) was a Greek historical writer. Sosicrates 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.
