St. Avertin, Confessor
HE was a holy deacon, who attended St. Thomas of Canterbury in his exile, and in all his troubles. After the martyrdom of that prelate, Avertin consecrated himself to the service of the poor and strangers at Vinzai, a village in Touraine, where he happily ended his course about 1189: see the new Martyrology of Evreux, that of Tours, &c. on the 5th of May.
