The local tradition, still curent, varies - that he was a prince, a brave chieftain, or a bishop - but it agrees in saying he was buried where the church tower now stands, and that over his grave a large mound was raised. We have here evidently traditions of two distinct persons, a chieftain and an ecclesiastic, who have become mixed up in the popular mind.

His Holy Well there, Ffynnon Garon, was at Eastertide, in days gone by, a centre of great attraction for the young of both sexes. On Easter Eve crowds of children resorted thither, each one bringing a small mug or cup and a quantity of brown sugar, and drank copious draughts of the water sweetened with sugar. On Easter Day, or Low Sunday, the swains met their sweethearts at the spot, and made them gifts of white bread (bara can), which they ate, washing it down with the crystal spring water in token of affection.

Edward Lhuyd gives us to understand that the parish church of Cellan, in Cardiganshire, which he writes "Keth-Lhan," is dedicated to [St Callwen], and that there is a spring there called "Ffynnon Calhwen." All Saints is the dedication now usually given to the church. On one of the mountains in the parish is a cistvaen called Bedd y Forwyn, the Virgin's Grave.

There are here two white stones, known as 'y fuwch wen a'r llo,' 'the white cow and calf,' standing close to one another on the moorland near the source of the Severn. They are best approached from Eisteddfa Gurig. The larger of the stones is 6 feet high, and the smaller 4 feet high. no local tradition would seem to be connected with them. -- Visited, 5th July, 1910.
