BAROCCHIO (or BAROZZI), GIACOMO  , called DA VIGNOLA (1507-1573), Italian architect, was born at Vignola in the Modenese territory on the Ist of October 1507 . His early work was conducted at Bologna, Piacenza, Assisi and Perugia, until he was summoned to Rome as papal architect under Pope Julius III . In 1564 he succeeded Michelangelo as the architect of St Peter's, and executed various portions of that fabric, besides a variety of works in Rome . The designs for the Escorial were also supplied by him . • He is the author of an excellent work on the Five Orders of Architecture (Rome, 1563), and another work on Practical Perspective (Rome, i583) . To his extensive acquirements and exquisite taste were superadded an amenity of manners and a noble generosity that won the affection and admiration of all who knew him . He died in Rome on the 7th of July 1573 . He was an eminent upholder of the classic style at a period when the style known as baroque was corrupting the architecture of Italy . The term baroque owes its origin to the Spanish word barrueco or berrueco, an imperfectly round pearl, and is not derived from the architect Barocchio, whose name so m . 74417 much resembles it, Yet it is curious that it was much used to describe a debased form of architecture encouraged by the Jesuits whose church in Rome was built by Barocchio .
