Lynceus (Ancient Greek: Λυγκεύς, "lynx-like") is in Greek mythology a Messenian prince, a son of Aphareus and brother of Idas, renowned for his extraordinarily keen eyesight. He sailed with the Argonauts, serving as the Argo's lookout, and joined the hunt for the Calydonian Boar. Together with Idas he killed Castor in the famous feud between the Apharetids and the Dioscuri, before being slain in turn by Castor's brother Pollux.

I.Overview
Lynceus (Ancient Greek: Λυγκεύς, romanized: Lunkeús, lit. 'lynx-like') is in Greek mythology a Messenian prince and one of the Argonauts, who served as a lookout on the Argo.
He also took part in the hunt for the Calydonian Boar.
II.Family
Lynceus was a son of Aphareus and Arene, or alternatively of Polydora or Laocoosa, and thus a brother of Idas and Peisus.
III.Mythology
Lynceus, together with his brother Idas, murdered Castor. He helped Idas to spot and kill Castor, and was in turn killed by Castor's brother Pollux, though he first managed to wound Pollux by throwing a rock. Idas and Lynceus murdered Castor because he and Pollux had kidnapped and married Phoebe and Hilaeira, the daughters of Leucippus, who were betrothed to Lynceus and Idas, or possibly to their relatives.
Lynceus was said to have excellent sight, enabling him to see through walls, trees, skin and the ground. According to some versions he was also able to see in the dark; in others his reputation for being able to see through the ground was simply a rumour that resulted from his knowledge of geology and gold-mining. This ability has been compared to x-ray photography and to Superman's x-ray vision.
