Petrus Thomae

He was an eminent Scotist who died while in prison on charges of sorcery.

In 1324–1325, he lectured at the University of Barcelona on the Sentences of Peter Lombard.

The commentary on the first book, Commentarium in primum librum Sententiarum, is preserved only in a single very poor manuscript.

It is partially preserved in an Italian manuscript of the fifteenth or sixteenth century containing fourteen fragments written in Hebrew script.

[13] The Liber de originali Virginis conceptione is dedicated to Archbishop John of Aragon.

It was written between 1320, when the archbishop was consecrated, and 1327, when his father, King James II, died.
