Pierre de la Vergne, aka Pierre de Veruche, Pierre Verneyo, Pierre Veruco, Pierre Verrujo or Pierre Veroche, Latin Petrus de Vernio (died 6 October 1403 in Avignon was a French cardinal.
Pierre de la Vergne studied Canon law at the University of Montpellier.[1] He was a disciple of Johannes Klenkok and was appointed cardinal deacon by Pope Gregory XI in 1371 taking the titular church Santa Maria in Via Lata.[2]
During the conflict about the Sachsenspiegel law book he handed the Decadicon - a written attack by Johannes Klenkok on the Sachsenspiegel - to Pope Gregory XI. Gregory considered the attack and later issued the papal bull Salvator humani generis condemning 14 articles of the Sachsenspiegel on 8 April 1374.[3]
De la Vergne participated in the papal conclave 1378 during which Pope Urban VI was elected[4] and later in 1378 in the papal conclave that elected Antipope Clement VII.[5] In 1379 he joined the Roman Obedience together with the other French cardinals.
