he constellation Virgo has lots of different origins depending on which mythology is being studied. Most myths generally view Virgo as a virgin maiden with heavy association with wheat. In Greek and Roman mythology they relate the constellation to Demeter, mother of Persephone, or Proserpina in Roman, the goddess of the harvest.
However, some tell tales of the Greek story of Parthenos, which means virgin in Greek, which explains how the actual constellation Virgo became to be.
