BORN DEC. 11, 1712, VENICE

died May 3, 1764, Pisa connoisseur of the arts and sciences, esteemed by the philosophers of the Enlightenment for his wide knowledge and elegant presentation of advanced ideas. Educated at Rome, Bologna, and Florence, Algarotti went to Paris at the age of 20. There his urbanity, his physical beauty, and his versatile intelligence promptly made an impression in intellectual circles. A year later he wrote Il Newtonianismo per le dame (1737; Newtonianism for Ladies), a popular exposition of Newtonian optics. Following a visit to Russia in 1739, he received an invitation to Prussia from Frederick the Great, which led to his staying more than nine years in Germany. Ill health eventually obliged him to return to Italy, first to Venice and then to Pisa. A monument on his tomb was inscribed with Algarottus non omnis ([Here lies] Algarotti not all). Algarotti's writings include several studies on classical themes and a number of stimulating essays on the subjects of architecture (1753), the opera (1755), and painting (1762).
