Acamas is a Greek masculine given name of unknown origin, possibly derived from 'akamas', meaning 'unfought' or 'invincible'. It appears in Greek mythology as the son of Theseus and Phaedra, fought in the Trojan War, and was a suitor for Penelope in Homer's Odyssey. In Christianity, Acamas was used as a martyr's name and several saints bore this name. Today, it is relatively rare but remains an attractive choice due to its rich history.
