Arce
messenger of the Titans and twin sister of Iris
Arke (Arce) was the twin sister of the rainbow-goddess Iris in Greek mythology. It was often thought that she was associated with the faded second rainbow that can at times be seen in the wake of the original.
During the great Titan-Wars, as Zeus raged against his father and elder family, Arke and her sister chose to fight on opposite sides. Iris became messenger for the Olympian gods and Arke fought with the Titans.
When the battle was won, leaving the Olympians victorious, Zeus cast Arke and her comarades into Tartaros, stripping her of her wings, and when Zeus came to the wedding of Peleus and Thetis, he brought these wings as a gift for Thetis.
