- Maria A. Phillips
(b nr Vigevano, ?1495; d after Aug 14, 1567).
Italian architect, engraver and writer. He is thought to have been in Rome by 1507, but the first specific record of him dates from 1526 when, together with Antonio da Sangallo (ii), Pier Francesco da Viterbo and Michele Sanmicheli, he worked for Pope Clement VII on the fortifications of Parma and Piacenza. After the sack of Rome in 1527, he was as much involved with restoration efforts as he was with recording antique monuments and participating in new building projects. Many existing drawings, some of them from the collection of Vasari (Florence, Uffizi), relate Labacco’s work to that of Sangallo, who commissioned him in 1539 to execute the large wooden model, now in the Vatican Museum, of his design for St Peter’s, Rome. The model required at least seven years to execute, and it was finished only after Sangallo’s death in 1546. Between 1546 and 1548 Labacco also published three engravings of Sangallo’s design....
