Eurymedon of Myrrhinus (Greek, Modern (1453-);: Εὐρυμέδων Μυρρινούσιος) married Plato's sister, Potone.[1] He was the father of Speusippus and was potentially the grandson of the elder Eurymedon. [2] His property was adjacent to that of Plato, and he is referred to as the executor of Plato's will. [3] Eurymedon is speculated to have been the grandson of an elder Eurymedon. Additionally, there is a possibility that he was the son of Speusippus. [4]
