Hymenaeus was the god of weddings or, more specifically, of the wedding hymn sung by the bride’s train as she was escorted to the house of the groom.
Hymenaeus was numbered amongst the Erotes, the youthful, winged gods of love. As a god of song he was usually described as a son of Apollo and one of the Muses. He 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.
