A Compendium of Irish Biography/Aengus
Aengus, King of Munster, lived in the 5th century. His father entertained St. Patrick hospitably at Cashel, and with Aengus, received from him baptism. It is related that whilst celebrating the rite the Saint unwittingly pierced Aengus' foot with his pointed staff, which the prince bore uncomplainingly, supposing it to be part of the ceremony instituted in remembrance of the Crucifixion. When Aengus became king he endowed the church in Munster with the triennial offering of 500 sheep, 500 pieces of linen, 500 pieces of cloth, and 500 balls of iron, which continued to be paid down to the time of Cormac MacCullinan.
