Cynisca

Cynisca, also written Kyniska, was a wealthy Spartan princess born around 440 BC. She is famous for being the first woman to win at the Olympic Games. She first entered the Olympics in 396 BC, where she won first prize competing with a team of horses that she had trained herself. In 392 BC she entered her horses a second time and was awarded another victory in the same event. Her wins in the equestrian contests of the ancient Games made her a landmark figure for women in the history of sport. The source lead does not name the event or give more of her life, so those details are left for later depth work.
