[1] Thrasymedes was the oldest son of King Nestor and Eurydice[2] (or Anaxibia[3]) and the elder brother of Antilochus.
His other siblings were Peisistratus, Pisidice, Polycaste, Perseus, Stratichus, Aretus, Echephron, and Antilochus.
Thrasymedes was one of the more prominent younger leaders portrayed in the Iliad, though not to the extent of his brother.
In the Iliad he was one of the lead sentries and was present at night when the Greek wall was built.
In the Odyssey, Telemachus visited him at Pylus whilst searching for news on his lost father Odysseus.
