Diomedes is the king of Argos and a Greek hero of the Trojan War. In some versions of the myth of Philoctetes, Diomedes (rather than Neoptolemus) accompanies Odysseus to Lemnos to retrieve Philoctetes. Diomedes does not arrive on Lemnos in Sophocles’s play, but he is mentioned many times. Diomedes is one of the men Philoctetes blames for marooning him on Lemnos, and Philoctetes deeply despises him as well as Odysseus. According to the elaborate lie concocted by Odysseus and delivered by the merchant, Diomedes is on his way to Lemnos with Odysseus to take Philoctetes and his bow and arrows to Troy by force.
