Hebe is the daughter of Zeus and Hera.  She is a representation of youth and Hera herself.  The original cupbearer of the Gods, Zeus later replaces her with Ganymede.  In many versions of myths surrounding Heracles, they end with a marriage between Heracles and Hebe.  One of the earliest examples of their marriage is found in the Homeric Hymns XV

This statue of Hebe located in Tompkins Square Park sits atop the temperance fountain and bears an amphora for carrying water.
