Among his early paintings are some altarpieces and religious themes. His first major documented work was an altarpiece for the church of San Pellegrino in 1732. In 1734, he completed frescoes in the walls and ceiling of the hall in Ca' Sagredo, representing the "Death of the giants". In the late 1730s, he began to specialize in the small-scale genre works that would lead him to be viewed in the future as the Venetian William Hogarth, painting subjects and events of everyday life in Venice. Longhi's gallant interior scenes reflect the 18th century's turn towards the private and the bourgeois, and were extremely popular.
