Sylvester Maurus

Sylvester Maurus was born in Spoleto, Italy, on 31 December 1619 to a noble family. He entered the Society of Jesus, 21 April 1636. After his novitiate, he spent three years (1639-1642) studying philosophy at the Roman College, where his principal teacher was Sforza Pallavicino. Following a period in which he taught grammar, Maurus studied theology from 1644 to 1648, again at the Roman College. Having completed his theological program, he taught philosophy at the Jesuit college in Macerata from 1649 to 1652. Recalled to Rome, he served a year as regent of studies for Jesuit seminarians. He took final vows in the Order in 1654, and five years later was promoted to the Chair of Theology, which he retained until his appointment in 1684 as Rector of the Roman College. Maurus died on 13 January 1687 in Rome.

His works include:
