He studied under Giovanni Bononcini in Rome between 1692 and 1697. From 1710 to 1727 he served as "‘Suonator di Violino, e Componitore di Musica’" to Prince . He also succeeded Corelli as director of the concertino at San Luigi dei Francesi, from 1710 to 1741. Though during his lifetime overshadowed by the likes of Corelli, Vivaldi, and Locatelli, his contribution to Italian baroque music is noteworthy, and many of his works were published throughout Europe.
