(Andrea), a celebrated Italian architect of the 16th century, was a native of Vicenza in Lombardy, and the disciple of Trissino. He made exact drawings of the principal works of antiquity to be met with at Rome, adding commentaries to them, which went through several impressions. But this, though a very useful work, was greatly exceeded by the Treatise of Architecture in four books, which he published in 1570. Inigo Jones wrote some excellent remarks on it; which were included in an edition of Palladio, published by Leoni, in 2 vols folio, 1742.
