The monument of Stefano Spada, a young nobleman from Lucca who died at the age of 24 years, suffers from its unfavourable location near the first pillar of the Montemirabile Chapel. The white marble aedicula was erected sometime after the death of Spada in 1563. It is decorated with the bust of the deceased in an oval niche and the coat-of-arms of the Spada family (two crossed swords). The exquisitely carved bust with the sad, dreaming expression is an excellent example of Renaissance portraiture.
