Hymen, Hymenaios or Hymenaeus, in ancient Greece, was a god of marriage ceremonies, inspiring feasts and song. Related to the god's name, a hymenaios is a genre of Greek lyric poetry sung during the procession of the bride to the groom's house in which the god is addressed. He was one of the winged love gods, Erotes and the son of a muse, Clio or Calliope or Urania or Terpsichore.
Hymen was supposed to attend every wedding. If he did not, then the marriage would supposedly prove disastrous, so the Greeks would run about calling his name aloud. He presided over many of the weddings in Greek mythology, for all the deities and their children.
