(Ἀριστόδημος), the Spartan, when the last battle at Thermopylae was expected, was lying with Eurytus sick at Alpeni; or as others related, they were together on an errand from the camp. Eurytus returned and fell among the Three Hundred. Aristodemus went home to Sparta. The Spartans made him ἄτιμος; "no man gave him light for his fire, no man spoke with him; he was called Aristodemus the coward" (ὁ τρέσας seems to have been the legal title; comp. Diod. 19.70). Stung with his treatment, next year at Plataea, B. C. 479, he fell in doing away his disgrace by the wildest feats of valour. The Spartans, however though they removed his ἀτιμία, refused him a share in the honours they paid to his fellows, Poseidonius, Philocyon, and Amompharetus, though he had outdone them.
