COZZARELLI, GIACOMO. - By Bartolomeo di Marco. Sculptor and architect, b. in Siena on 20 Nov. 1455, d. on 23 March 1515. He resided in Urbino from the time when Francesco di Giorgio Martini had moved there (1477); he had some part in the internal decoration of the Ducal Palace; as architect to the Magnificent Pandolfo Petrucci, tyrant of Siena, he enlarged the church and convent of S. Maria Maddalena at Porta Tufi (c. 1484, destroyed in 1526), worked on the enlargement of the church and convent of S. Bernardino at the Osservanza, and executed the Palazzo del Magnifico.
Of the sculptures recorded by Sigismondo Tizio only the wooden statue of S. Vincenzo Ferreri in S. Spirito, the terracotta figure of S. Sigismondo in the sacristy of the Carmine convent, and the most elegant bronze brackets on the exterior of the Palazzo del Magnifico remain; whereas the stucco roundels with Evangelists, Doctors of the Church, and Franciscan saints in the basilica of the Osservanza were almost completely destroyed by bombing (1944). Nevertheless, to him may with good probability be attributed the marble tomb of G. B. Tondi (d. 1512) in the atrium of the Spedale della Scala; the large Lamentation over the Dead Christ, in terracotta, in the sacristy of the Osservanza; the terracotta statues of S. Lucia and S. Niccolò in the Oratory of S. Lucia, and the wooden statue of S. Niccolò da Tolentino in S. Agostino. He is the most characteristic representative of the taste and artistic culture in Siena at the beginning of the 16th century. - See pl. XLVI.
