late Neapolitan Baroque painter who created great, animated compositions, superficial in content but dazzling in colour and in execution.

Conca studied in Naples under Francesco Solimena. In 1706, along with his brother Giovanni, who acted as his assistant, he settled in Rome. He was patronized by Cardinal Pietro Ottoboni, who introduced him to Pope Clement XI. The pope commissioned him to paint frescoes in San Clemente and San Giovanni in Laterano and The Crowning of St. Cecilia in Santa Cecilia in Trastevere (1725). His pictures in the grand manner were also sought by the royalty of Spain, Portugal, and Poland and by the elector of Cologne. He returned to Naples in 1751, where he executed more religious frescoes—e.g., Solomon and the Queen of Sheba in Sta. Chiara.
