Andrea Palladio, an Italian architect, born in Yicenza, Nov. 30,1518, died there in August, 1580. He was brought into notice by his design for the loggie or open porticoes surrounding three sides of the palazzo della Ragione at Vicenza, after which he was for many years busily employed in the construction of private mansions, developing the still popular Palladian style. The most famous is the Rotonda Capra, known as Palladio's villa, just outside of Vicenza. After a time he was invited to Venice, where he designed two churches, San Giorgio Maggiore and II Santissimo Redentore, as well as the atrium for the convent della Caritd and the facade of San Francesco della Vigna. He also designed the Palazzo Barbaro at Maser in the Trevigiano, and a palace at Montagnana for Francesco Pisano. His last work was the Tea-tro Olimpico at Vicenza, which has been the subject of very conflicting criticisms; it was not finished until after his death. He wrote a treatise on architecture (fol., Venice, 1570), several times reprinted in costly style.
