Mattia de Rossi

Mattia de Rossi (14 January 1637 – 2 August 1695) was an Italian architect of the Baroque period, active mainly in Rome and surrounding towns.

Biography

Born in Rome to a family of architects and artisans, he rose to prominence under the mentorship of Gian Lorenzo Bernini, and even inherited the position as chief architect of the Fabbrica di San Pietro (Workshop of St. Peter's Basilica) in 1680 after the master died. In that post, he continued the work that had been started by Bernini on the outside colonnade and the Ponte Sant’Angelo.

He worked during a period with notable competitors, including the prolific Carlo Fontana. Among his works are the facades of the churches of St. Gall and San Francesco a Ripa (built 1681-1701); finishing touches or reconstruction for Sant'Andrea al Quirinale, Santa Maria di Montesanto, and Santa Croce e San Bonaventura dei Lucchesi; the customs office in Ripa Grande; the Palazzo Muti Papazzurri (attributed, 1660); the tomb monument to Giovanna Garzoni in Santi Luca e Martina; the Mausoleum of Leo X; and the monument to Clement X in St. Peter's Basilica. This latter funereal monument was designed by de Rossi, but the sculptures were completed by Lazzaro Morelli, Ercole Ferrata and Giuseppe Mazzuoli.
