Hermocrates
Hermocrates is one of the participants in Plato’s Dialogue Timaeus. Some scholars argue that Plato intended to write a trilogy of dialogues that included Timaeus and Critias with Hermocrates as the third dialogue with the tantalising possibility of further references to Atlantis.
*In Critias 108 it is implied that Hermocrates has a major contribution to make, as it twice mentions that he is due to deliver a speech, apparently the following day.*
Historically, Hermocrates is believed to have been a Sicilian statesman and the general who defeated an Athenian assault on his native Syracuse circa 414 BC.
