(Paul), a learned Jesuit, born at Placentia in 1617, entered early among the Jesuits; and, after having taught mathematics and divinity at Rome, was sent into Sweden to queen Christina, whom he prevailed on to embrace the papist religion. He wrote,

1. Vacuum proscriptum. 2. Terra machinis mota. 3. Mechanicorum, libri octo. 4. De Igni Dissertations; which is much esteemed. 5. De Angelis Disputatione Theologica. 6. Hydrostaticae Dissertations. 7. Opticae Dissertations.

It is remarkable that he wrote this treatise on optics at 88 years of age, and after he was blind. He also wrote several books in Italian.
