Vorilongus, Gulielmus a French Dominican of the 15th century, was called to Rome by pope Pius II to defend his order against the Franciscans relative to the blood of Christ. He wrote a Commentary on the Four Books of Sentences (Lyons, 1484), and a collection of passages from the Sentences, which are against Scotus. He died at Rome in 1464.
