Riccati, Vincent

, an able mathematician, was born in 1707 at Castel Franco, in the territory of Treviso, and in 1726 entered among the Jesuits, and taught mathematics at Bologna, till the suppression of his order in 1773. At this period he returned to his native place, and died there of a cholic, in 1775, aged sixty-eight, leaving some good mathematical works among others, a large treatise on the “Integral Calculus,” 3 vols. 4to. He had been much employed in hydraulics, and such was the importance of his services in this branch, that the republic of Venice ordered a gold medal, worth a thousand livres, to be struck in honour of him, in 1774. ²
