Carlo Maderno (1556 – 30 January 1629) was an Italian architect, born in today's Ticino, who is remembered as one of the fathers of Baroque architecture. His façades of Santa Susanna, St. Peter's Basilica and Sant'Andrea della Valle were of key importance in the evolution of the Italian Baroque. He is often referred to as the brother of sculptor Stefano Maderno, but this is not universally agreed upon.
Born in Capolago, in today's Ticino, which was at the time a bailiwick of the Swiss Confederacy, Maderno began his career in the marble quarries of the far north, before moving to Rome in 1588 with four of his brothers to assist his uncle Domenico Fontana. He worked initially as a marble cutter, and his background in sculptural workmanship would help mold his architecture. His first solo project, in 1596, was an utterly confident and mature façade for the ancient church of Santa Susanna (1597–1603); it was among the first Baroque façades to break with the Mannerist conventions that are exemplified in the Gesù. The structure is a dynamic rhythm of columns and pilasters, with a protruding central bay and condensed central decoration add complexity to the structure. There is an incipient playfulness with the rules of classic design, still maintaining rigor.
The Santa Susanna façade won the attention of Pope Paul V, who in about 1603 appointed him chief architect of St Peter's. Maderno was forced to modify Michelangelo's plans for the Basilica and provide designs for an extended nave with a palatial façade. The façade (completed 1612) is constructed to allow for Papal blessings from the emphatically enriched balcony above the central door. This forward extension of the basilica (which grew from Michelangelo's Greek cross to the present Latin cross) has been criticized because it blocks the view of the dome when seen from the Piazza and often ignores the fact that the approaching avenue is modern. Maderno did not have as much freedom in designing this building as he had for others structures.
Most of Maderno's work continued to be the remodelling of existing structures. The only building designed by Maderno and completed under his supervision was the little Santa Maria della Vittoria (1608–20), where Maderno's masterwork is often ignored in favor of Bernini's Cornaro Chapel and its Ecstasy of St Theresa and where the churches' public façade is not by Maderno.
Even Maderno's masterpiece, the church of Sant'Andrea della Valle, is not entirely his. There he designed the façade and executed the dome, the second largest in the Roman skyline. The church itself had been designed for the Theatines by Giuseppe Francesco Grimaldi and Giacomo della Porta in 1540: it follows a familiar Jesuit plan, cruciform, its wide nave without aisles, with chapels beyond arched openings. The crossing contains the high altar, lit under Maderno's dome (frescoed by Giovanni Lanfranco 1621—25) on its high windowed drum. The earliest design is of 1608; construction took from 1621 to 1625. At Maderno's death, the façade remained half built; it was completed to Maderno's original conception by Carlo Fontana. In this façade, the standard formula established at Il Gesù is given more movement and depth—in the varying planes of the frieze and cornice—and increased chiaroscuro —as in the whole columns embedded in snug dark recesses that outline their profiles with shadow—, and in similar elements that are re-grouped for a tighter, more sprung rhythm.
His other works include the Roman churches of Gesù e Maria, San Giacomo degli Incurabili, Santa Lucia in Selci and San Giovanni dei Fiorentini (where he is buried). In addition, he worked on the Quirinal Palace, the Papal palace in Castel Gandolfo and the Palazzo Barberini and for the Barberini Pope Urban VIII (1628 and completed 1633; much remodeled since). In the Palazzo Barberini at Quattro Fontane, Maderno's work is overshadowed at times by details added by Bernini and Borromini. His design of palaces is best represented by his design of Palazzo Mattei (1598–1616).
