Acamas (son of Theseus)

Acamas (/ɑːˈkɑːmɑːs/), the son of Phaedra and Theseus, and brother or half brother to Demophon, was a character in the Trojan War.

After his father was exiled from Athens, he and his brother were sent to Euboea, where they grew to adulthood and allied themselves with Euboea's King Elephenor. Prior to the assault of Troy by the Greeks, he and Diomedes were sent to demand the surrender of Helen (this expedition Homer ascribes to Menelaus and Odysseus), but during his stay at Troy he won the affection of Laodice, daughter of Priam, and begot by her a son, Munitus, who was brought up by Aethra, grandmother of Acamas. He was killed by the bite of a snake while hunting at Olynthus in Thrace.

In the war, Acamas fought on the side of the Greeks. After the war, he rescued his grandmother, Aethra, who was being held captive in Troy as Helen's maid. Later mythological traditions describe the two brothers embarking on other adventures as well, including the capture of the Palladium. Some sources relate of Acamas the story which is more commonly told of his brother Demophon, namely the one of his relationship with Phyllis of Thrace. This might be a mistake.
