PORTA, Guglielmo della
(b. ca. 1505, Porlezza, d. 1577, Roma)

Baldacchino

1530-32
Marble
Chapel of San Giovanni Battista, Cathedral, Genoa

In 1530 Giovanni Giacomo transferred his studio to Genoa, where, from 1532, he collaborated with Niccolò da Corte. The partnership was formalized in 1534, when Giovanni Giacomo, his son Guglielmo and da Corte set up a studio together, and it continued until 1537 when da Corte went to Spain and Guglielmo presumably went to Rome. The most important commissions undertaken by this partnership were the baldacchino in the chapel of San Giovanni Battista (1530-32).

A number of reliefs of prophets on the socles of the baldacchino have been identified as Guglielmo's earliest works. However, only the unidentified figure on the rear side of the right-hand socle can be attributed wholly to Guglielmo.
