THEODORUS PELTEN. - Jesuit, theologian, born in Pelta (Overpelt, Belgium), from which he took his name, c. 1510, died in Augsburg on 2 May 1584. He was among the first professors of the Roman College, then taught Greek, Latin, and Hebrew in Naples. He later became professor of theology at Ingolstadt, Munich, and again at Ingolstadt for twelve years (1562–74). His great erudition was widely admired, especially since he had begun his studies late, after apparently having worked as a shoemaker. P. was also one of the most effective defenders of Catholic doctrine against Protestants.
His principal works are polemical in nature. At the University of Ingolstadt, under his direction, the following theses were defended: *De maiestate hominis Christi* (Ingolstadt 1564); *De Extremae Unctionis Sacramento* (ibid. 1565); *De Baptismo* (ibid. 1566); *De S.mo Eucharistiae Sacramento* (ibid. 1566); *Commentatio de indulgentiis ecclesiasticis* (ibid. 1566). Up to 1572, the theses defended under P. covered all matters of controversy with Protestants, as well as other theological topics.
Works composed by P. himself after leaving Ingolstadt include: *De nostra satisfactione et Purgatorio* (Cologne 1576); *De originis peccato disceptatio*, *item de Christi satisfactione et maiestate* (ibid. 1576).
He also published important texts and translations, including *S. Ioannis Chrysostomi... in Dievi Pauli epistolas* (Paris 1596, an edition also found in the *Bibl. maxima Patrum* of *Id. inus. huc. de eiusdem*).
*Id. inus. huc. de eiusdem*.

In the monastery of P. lived St. Isidore (v.), known as the Pelusiote. With the Muslim conquest of 639, the city declined.
