Antonio Caldara (1670 or 1671 - December 26, 1736) was an Italian Baroque composer. Caldara was born in Venice (exact date unknown), the son of a violinist. He became a chorister at St Mark's Cathedral also in Venice, where he learned several instruments, probably under the instruction of Giovanni Legrenzi. In 1699 he relocated to Mantua, where he became maestro di cappella to the Duke. He remained there until 1707, then moved on to Rome, becoming maestro di cappella to Prince Ruspoli.
