Aengus

In Irish mythology, Aengus or Óengus is one of the Tuatha Dé Danann and probably originally a god associated with youth, love, summer and poetic inspiration. The son of The Dagda and Boann, Aengus is also known as Macan Óc ("the young boy" or "young son"), and corresponds to the Welsh mythical figure Mabon and the Celtic god Maponos. He plays a central role in five Irish myths. Name In Old Irish his name is Óengus or Oíngus , a name attested in Adomnán's Life of St Columba as Oinogus(s)ius. This is believed to come from a Proto-Celtic name meaning "true vigour". The medieval Dindsenchas derives it from "one desire", explaining that Boann gave him the name because her union with the Dagda had been her only desire. In Middle Irish this became Áengus, and in Modern Irish Aonghus , . He is also known as Óengus Óc/Aengus Óg ("Aengus the young"), Mac ind Óc ("son of the young"), Maccan/Macán, or Mac Óc/Mac Óg ("young son"). According to Celticists John T. Koch and Kenneth H. Jackson, Aengus is also cognate to the Pictish Onuist/Unuist and Old Welsh Unust.
