GIACOMO of Lausanne – Dominican theologian and preacher, born in Lausanne around the middle of the 13th century, died at Pons in 1321. He served on the commission appointed by the Master General of the Dominicans to examine the doctrine of Durand of St-Pourçain (1313–14). From 1318 until his death he was Provincial of France.
Of him there survive the first two books of the Commentary on the Sentences (Vienna, Staatsbibliothek, ms. 1542), many sermons, and various moral commentaries on almost all the books of Holy Scripture. The following have been published: Sermones dominicales et festivales (Paris 1530); Opus moralitatum (Limoges 1528, extracts from his moral commentaries on Holy Scripture).
