Aonghus is the Irish god of love with multiple names. Oengus, Aengus, Aengus Og ("Aengus the young"), Mac ind Og ("Son of the Young"), Mac Og ("Young Son") and Maccan. He is also one of the Tuatha De Danann.
He is the son of Dagda and Boann, with Aonghus' wisdom later saying his father Dagda from starving to death.
A story about Aonghus relates to how he fell in love with a maiden he saw that he earlier dreamt of. He became ill with longing for her and with concern from his parents they sought the identity of the maiden. She happened to be Caer Ibormeith, whom Aonghus later went to see her again at a lake to declare his love for her he was transformed into a swan and the two flew together (with Caer accepting his love).
