COZZARELLI, GIACOMO. - Son of 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 Francesco di Giorgio Martini moved there (1477); he took some part in the interior decoration of the Ducal palace; as architect to the Magnifico Pandolfo Petrucci, tyrant of Siena, he built the church and convent of S. M. Maddalena at Porta Tufi (ca. 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 mentioned by Sigismondo Tizio, only the wooden statue of S. Vincenzo Ferreri in S. Spirito, the terracotta statue 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, while the stucco roundels depicting Evangelists, Doctors of the Church, and Franciscan saints in the basilica of the Osservanza were almost completely destroyed by bombing (1944). With considerable probability, however, the marble tomb of G. B. Tondi (d. 1512) in the atrium of the Spedale della Scala; the large terracotta Lamentation over the Dead Christ in the sacristy of the Osservanza; the terracotta statues of S. Lucia and S. Niccolò in the Oratorio di S. Lucia; and the wooden statue of S. Niccolò da Tolentino in S. Agostino may be attributed to him. He is the most characteristic representative of artistic taste and culture in Siena at the beginning of the 16th century. - Vedi tav. XLVI.
