BREGNO, Andrea
(b. 1418, Osteno, d. 1503, Roma)

Piccolomini Altar

1481-85
Marble
Duomo, Siena

After the departure from Rome of Dalmata and Mino da Fiesole, the supremacy in Rome of Bregno and his bottega was uncontested, while his fame as a sculptor spread all over Italy. Thus between 1481 and 1485, together with his assistants, he composed the Piccolomini Altar (signed and dated 1485) in Siena Cathedral, which was later embellished with sculptures (1501-04) by Michelangelo.

The Piccolomini Altarpiece is an architectural and sculptural altarpiece in the left-nave of Siena Cathedral, commissioned by cardinal Francesco Todeschini Piccolomini who expected it to become his tomb. However, he was elected Pope Pius III and buried in the Vatican. It was built between 1481 and 1485 by Andrea Bregno in Carrara marble, with additions in the following decades - these included four niche sculptures produced between 1501 and 1504 by Michelangelo of Sts Peter, Augustine (later resculpted as Saint Pius), Paul and Gregory. On top of the altar is the Madonna and Child, a sculpture (probably) by Jacopo della Quercia. The central painting of the Madonna is by Paolo di Giovanni Fei and from the late 14th century.

The altarpiece was restored in 2008.
