She is also said to travel on the rainbow while carrying messages from the gods to mortals. During the Titan War, Zeus tore Arke's iridescent wings from her and gave them as a gift to the Nereid Thetis at her wedding, who in turn gave them to her son, Achilles, who wore them on his feet. Achilles was sometimes known as podarkes (feet like [the wings of] Arke).
