Parthenopeus was one of the leaders that participated in the story of the Seven Against Thebes in Greek mythology. He was the son of Atalanta and either Hippomenes, Meleager or Ares. Her mother left him on Mount Parthenius, so that she would hide the fact that she was no longer virgin. This is where his name comes from, meaning seemingly virginal. The boy was saved by a shepherd and raised to adulthood.
