Thetis, the mother of Achilles, is a powerful goddess in her own right, and Hera takes a moment to remind Zeus that she (Hera) raised Thetis herself. She has an almost grandmotherly relationship to Achilles. Hera is so often associated with the persecution of women and children embroiled in her husband’s desires, we almost overlook that she can be maternal even with children who aren’t her own, so long as her jealousy isn’t roused.
