Bertius, Petrus born in Flanders, November 14, 1565, became regent of the college of the States at Leyden, and professor of philosophy. Having embraced the opinions of Arminius, he drew upon himself the enmity of the Gomarists, and was stripped of his employments. Upon this he removed to France, where, in 1620, he joined the Roman Catholic Church, and was nominated to the professorship of eloquence in the college of Boncourt. He afterward became historiographer to the king, and died October 3, 1629. Among his works are,
1. Notitia Episcopatuum Galliae (Paris, 1625, fol.): —
2. Theatrum Geographiae veteris (Amst. 1618-19, 2 vols. fol.). See Mosheim, Ch. Hist. 3, 300.
