Simmias of Thebes appears as a main discussion partner in a dialogue from the man who founded what?
Plato Plato ( ; Greek: Πλάτων "Plátōn", ] in Classical Attic; 428/427 or 424/423 – 348/347 BC) was a philosopher in Classical Greece and the founder of the Academy in Athens, the first institution of higher learning in the Western world. He is widely considered the most pivotal figure in the development of philosophy, especially the Western tradition. Unlike nearly all of his philosophical contemporaries, Plato's entire work is believed to have survived intact for over 2,400 years. Others believe that the oldest extant manuscript dates to around AD 895, 1100 years after Plato's death. This makes it difficult to know exactly what Plato wrote.
Epaminondas Epaminondas ( ; Greek: Ἐπαμεινώνδας , "Epameinondas"; d. 362 BC) was a Theban general and statesman of the 4th century BC who transformed the Ancient Greek city-state of Thebes, leading it out of Spartan subjugation into a pre-eminent position in Greek politics. In the process he broke Spartan military power with his victory at Leuctra and liberated the Messenian helots, a group of Peloponnesian Greeks who had been enslaved under Spartan rule for some 230 years after being defeated in the Messenian War ending in 600 BC. Epaminondas reshaped the political map of Greece, fragmented old alliances, created new ones, and supervised the construction of entire cities. He was also militarily influential and invented and implemented several major battlefield tactics.
