Амфион
Lycus' death did not restore Laius to the throne. Amphion and Zethus seized power, ruling as joint kings of Thebes, and expelled Laius. Amphion's wife was Niobe, daughter of Tantalus, and they had seven sons and seven daughters together. Amphion and Zethus expanded the city (and renamed it Thebes) and built the seven gates of Thebes, naming them after Amphion's daughters (Thera, Cleodoxa, Astynome, Astycratia, Chias, Ogygia, Chloris). Niobe, a boastful woman, attracted the wrath of Artemis and her brother Apollo, who were furious at Niobe for taunting their mother. Artemis then decided to kill all of her daughters while Apollo killed all of her sons, thus all of her children were killed. Amphion committed suicide after the death of his beloved children. Zethus' son and only child had been killed earlier, and Zethus had died of a broken heart.
