GIOVANNI 
          LORENZO BERNINI was, in the assessment of Janson (History of Art, 
          p. 410), the greatest sculptor-architect of the 17th century. He began 
          his career as a student of his father Pietro Bernini (1582-1629), a 
          sculptor who had himself worked at one time with Camillo 
          Mariani.   
        
Later 
          he attracted the patronage of Cardinal Maffeo Barberini, for whom he 
          designed a palace. When Barberini was subsequently installed as Pope 
          Urban VIII, 1623, Bernini was put in charge of building operations at 
          St. Peter's Basilica at the Vatican, where one of his early works, 1624-33, 
          was the canopy [baldachin] over the high altar. He also created, 1657-66, 
          the soaring marble, gilded bronze and stucco Chair of St. Peter [Cathedra 
          Petri] for the Basilica.  
        
Bernini's 
          baroque style was a powerful influence on the architecture of his period. 
          His most famous architectural works are the symmetrical curved colonnades 
          of St. Peter's, the facade of Barberini's palace, and the arsenal at 
          Civita Vecchia. Late in his career Bernini designed a series of three 
          churches, culminating in the domed Sant' Andrea al Quirinale, 1658-70, 
          in Rome.  
        
In 
          sculpture, Bernini's masterwork is the Cornaro 
          Chapel at the Church of S. Maria della Vittoria in Rome, commissioned 
          by Cardinal Patriarch Federico Cornaro (G-17). 
          The centerpiece is The Ecstasy of S. Teresa of Avila, a large 
          statue designed to be illuminated by reflected light from a hidden window. 
          The figures of S. Teresa and an angel are seen upon a stage, witnessed 
          by seven Cardinals and a Doge of the Cornaro family looking on from 
          flanking balconies. The Fountain of the Four Rivers, 1648-51, in Piazza 
          Navona is another of his celebrated sculptural groups.
