Francesco, Count, was born at Venice in 1712. Led by curiosity, as well as a desire of improvement, he travelled early into foreign countries; and in 1733 visited Paris. Here he composed his Newtonian Philosophy for the Ladies, as Fontenelle had done his Cartesian Astronomy, in the work entitled The Plurality of Worlds. He was much honoured by Frederick the Great, who, when crowned at Königsberg in 1740, created Algarotti a count of Prussia. He died at Pisa the 23rd of May 1764, and ordered his own mausoleum, with this inscription, Hic jacet Algarottus, sed non omnis. He is allowed to have been a very great connoisseur in painting, sculpture, and architecture; and he contributed much to the reformation of the Italian opera. His works, which are numerous, and upon a variety of subjects, abound with vivacity, elegance, and wit. They were printed at Leghorn in 1764, in 6 vols. 12mo.
