Iphicles

Two serpents sent by Hera entered the crib where Iphicles and Heracles lay. Iphicles was terrified, while Heracles strangled them and saved both children. They were twin brothers with different fathers. Alcmena was the mother of both. Iphicles was the son of Amphitryon, her mortal husband, while Heracles was the son of Zeus.

Iphicles took part in the hunt for the Calydonian Boar. He later joined Heracles in the attack on Troy and its king, Laomedon. He also joined Heracles in a campaign against Sparta and was killed there. He remained a mortal companion and kinsman of Heracles, rather than the central figure of an independent myth.
