This strong spring rises within a short distance of the ruined church of Llandilo Llwydiarth, near Maenclochog, in Pembrokeshire, and close by, there is a farm-house in which a skull, traditionally called "Penglog Teilo," (Teilo's Skull) is kept, and has been kept from time immemorial. This skull is used for drinking water out of from St. Teilo's Well. In former times St. Teilo's Well had a wide-spread reputation as a healing well, and the sick from all parts of South Wales resorted to it; but it was considered absolutely necessary to drink the water out of the skull, which had to be dipped in the well, and filled with water, and handed to the patient by the hereditary keeper. The present keeper of the relic is Mr. Melchior, an intelligent farmer, who informed me that his ancestors had been keepers of the skull from time immemorial. How the skull first came there, Mr. Gibby, of Llangolman, gave the following tradition:--When St. Teilo was dying he bade a female servant take his skull from Llandilo, in Carmarthenshire, to Llandilo, in Pembrokeshire, and that if this was done, the skull would be a blessing to coming generations of men who would have their health restored by drinking water out of it. According to another tradition which I have heard, the skull came from Llandaff Cathedral, where St. Teilo was Bishop, though born in the neighbourhood of Tenby. If we believe the old legend, the miracles he worked in death were marvellous; for, "on the night of his decease, there arose a great dispute between the clergy of the three Churches each asserting its authority and privileges for obtaining his body; but at length, attending to the advice of discreet men, they had recourse to fasting and prayer, that Christ, the great judge, who is the true authority, and privilege of holy persons, should declare by some sign, to which of them he would be pleased to commit the body of the saint. And in the morning a certain elder, looking towards the place where the body was, spoke with a loud voice, saying, "Our prayer, brethren, has been heard by the Lord, who deprives no one of his reward; arise, and behold what things have been done by Christ the meditator between God and man, that our dispute might be settled; and as in the life so in the death of the holy confessor, Teilo, miracles should be performed." For, lo! they saw there three bodies, to which there was the same dimensions of body, the same beauty of countenance; they had the lineaments of the whole frame, without any difference. So peace being restored, each with their own corpse returned homewards, and they buried the different bodies in those several places with the greatest reverence."
