Tydecho

Saint Tydecho was a Welsh saint of the sixth century, a cousin and companion of Saint Cadfan. Several churches in Wales are dedicated to him.

The Life of Saint Padarn counts him among the saints who came to Wales from Armorica. Tradition says that he came in the time of King Arthur and became an anchorite after the king's death. He lived in the region of Mawddwy with his sister Tegfedd and founded churches at Llanymawddwy, Mallwyd, Garthbeibio and Cemmaes. Legends say that he slept on rocks, wore a hair shirt and worked the land, and that when the prince Maelgwn Gwynedd took his oxen, he found him ploughing with two wild stags with a grey wolf pulling the harrow; the prince begged forgiveness and granted his land the right of sanctuary. Another legend tells that he turned a stream into milk. His feast is kept on 17 December.

He is a saint of the undivided Church, commemorated on 17 December (New Calendar).
