Tractatus de Purgatorio Sancti Patricii

Tractatus de Purgatorio Sancti Patricii (Treatise on Saint Patrick's Purgatory) is a Latin text written about 1180–1184 by a monk who identified himself as H. of Saltrey. The author is traditionally known as Henry, though this was an insertion and invention of Matthew of Paris and has been contested in the influential work of historian Jacques le Goff.^[1] H de Saltrey was a Cistercian in Huntingdonshire.
