PICCOLOMINI, FRANCESCO, of the same family with the preceding, was born in the year 1520, and taught philosophy with success for the space of twenty-two years, at Siena, Perugia, and Padua. He afterwards retired to Siena, where he died in 1604, at the age of eighty-four. This city went into mourning on the occasion of his death. His works are,—Some Commentaries upon Aristotle, printed at Mayence, 1608, in 4to; and Universa Philosophia de Moribus, printed at Venice, 1583, in folio. The latter is his principal work. He laboured to revive the doctrines of Plato, and endeavoured also to imitate the manners of that philosopher. He had as his principal rival the famous Zambarella, whom he excelled in facility of expression and neatness of discourse, but to whom he was much inferior in point of argument.
