In Greek mythology, Timalcus (Ancient Greek: Τίμαλκον) was a Megarian prince as the son of Megareus, eponymous king of Megara.
[1] Timalcus’ mother was Iphinoe, daughter of King Nisus of Megara.
[2] He was the brother of Evaechme, wife of Alcathous,[3] and Evippus who was slain by the Cithaeronian lion.
[4] Timalcus was killed by Theseus while he was in the campaign with the Dioscuri against Aphidnae but this seems unbelievable as Alcman wrote a poem on the Dioscuri, in which he says that the twin sons of Zeus captured Athens and carried into captivity Aethra, mother of Theseus, but the latter himself was absent.
