Wonder Woman by George Pérez #1

The Olympian goddesses create the Amazons to teach humanity the ways of Gaea. After the Amazons forget their purpose, and fall prey to the machinations of Ares, a group of Amazons led by Hippolyte rededicate themselves to their task. Time passes, and when Hippolyte yearns for the child she never had, the goddesses tell her to create a child from clay, which they animate, and whom the queen names Diana. After Diana has grown, the goddesses ask the Amazons to choose a champion to confront a new scheme of Ares'. Diana wins the competition to be champion and heads out into Patriarch's World.
