of these plays are lost, and only testimonia and fragments remain. A fragment of Aeschylus' Palamedes ("On account of what injury did you kill my son?") seems to assure that in that play, Nauplius came to Troy and protested his son's death. Sophocles has Nauplius give a speech in defense of Palamedes, listing his many inventions and discoveries, which much benefitted the Greek army. In Euripides' Palamedes, Nauplius' son Oeax, who was with his brother Palamedes at Troy, decides to inform their father of the death of Palamedes, by inscribing the story on several oar-blades and casting them into the sea, in hopes that one would float back to Greece and be found by Nauplius. The attempt apparently succeeds and Nauplius comes to Troy. Several other plays also, presumably, dealt with this story. Philocles, Aeschlyus' nephew and a contemporary of Euripides, wrote a play titled Nauplius. Nauplius, and Palamedes, were the titles of two plays by the 4th century BC Attic tragedian Astydamas the Younger, And the 3rd century BC poet Lycophron also wrote a play with the title Nauplius. The Argonaut Nauplius was also the name of one of the Argonauts, who was one of those who volunteered to steer the Argo after Tiphys' death. According to Apollonius of Rhodes, he was the son of Clytonaeus and a direct descendant of the son of Poseidon and Amymone, via the lineage: Nauplius – Proetus – Lernus – Naubolus – Clytoneus – Nauplius. However, for Hyginus, the son of Poseidon was the same person as the Argonaut. Although it would be more plausible for an Argonaut to be still alive at the time of the Trojan War, than for a son of Poseidon and Amymone, and therefore more plausible for the father of Palamedes to be the same as the Argonaut (rather than being the son of Poseidon), no surviving ancient source identifies the Argonaut with the father of Palamedes.
