Salmoneus was the son of Aeolus and Enarete in Greek mythology. As such, he was the brother of Sisyphus, Athamas, Cretheus, Athamas, Arne, Cephalus and Alcyone. His daughter by Alcidice was Tyro. Through Tyro's marriage to her uncle Cretheus, Salmoneus was the grandfather of Amythaon, Pheres and Aeson (and thus ancestor of Melampus and Jason). Through Tyro's affair with Poseidon, Salmoneus was the grandfather of Neleus and Pelias (and thus grandfather of Nestor).
Sisyphus and Tyro
Salmoneus and Sisyphus were rivals. Sisyphus was told by an oracle that, if he married Tyro, she would bear a child that would kill Salmoneus. At first, Tyro married Sisyphus and bore his son but, after hearing what the child would do, she killed it.
Salmoneus ordered his subjects to worship him. He did this by pretending to be Zeus; he built a bridge of brass, over which he drove at full speed in his chariot to imitate thunder, the effect being heightened by dried skins and cauldrons trailing behind while torches were thrown into the air to represent lightning. For his excessive pride, he was struck down by Zeus. and confined to Tartarus (as his the death-defying Sisyphus would also be).
