30 January. Scottish calendars give short notices of this saint, who is said to have been an illustrious and saintly bishop during the reign of King Achaius, a Scottish king contemporaneous with Charlemagne. Very few particulars can be ascertained as to his life. All that is at present known of him is gathered from the traces of his cultus which remain in various districts of the country. Thus the parish of Kinglassie, near Kirkcaldy, seems to have been named after him, and in the neighbourhood is a spring of fine water known as Saint Glass’s Well. There is another well named after him at Dundrennan (Kirkcudbrightshire). Kilmaglas, now known as Stachur, in Argyleshire, indicates another dedication to this saint. His feast is noted in the Breviary of Aberdeen on this day.
