Iris was the daughter of Thaumas, one of the minor sea gods, and the Oceanid Electra. Her sisters were the Harpies, Aello, and Ocypete. She also had a twin sister, Arke, who served as messenger for the Titans during their war with the Olympias and was thrown into Tartarus with her masters by Zeus after ripping her wings off. As the sun unites Earth and heaven, Iris linked the gods to humanity. She traveled with the speed of wind from one end of the world to the other, and into the depths of the sea and Underworld. She was married to Zephyrus, god of the west wind and one of the Anemoi. Their son was Pothos. She wielded a pitcher of water originating from the River Styx. Whoever promises to tell the truth and lies, she used it to put the liar to sleep. She was said to bear golden wings of a butterfly.
