Alessandro Pieroni

He was active mainly in a Mannerist style, working for the courts of Grandukes Francesco I and Ferdinando I de' Medici, Grand Duke of Tuscany.

In 1589, he was among the artists engaged in the elaborate decorations to celebrate the marriage of Ferdinando I and Cristina di Lorraine, painting the Defeat of Gian Galeazzo Visconti at Mantua.

As an architect, he worked with Bernardo Buontalenti in the design of fortifications of the Belvedere in Florence and the Corsini Chapel in church of the Carmine, and the facade of Santa Maria del Fiore.

In Volterra, he helped design the Chapel of St Paul for the Admiral Jacopo Inghirami (and paint the main altarpiece).

[2] His son Giovanni de Galliano Pieroni was an architect; in addition, the elder Pieroni collaborated with Don Giovanni de' Medici, the illegitimate son of Cosimo who dabbled in architecture, mainly the facade of Santo Stefano dei Cavalieri in Pisa.
