Starting in 1717, he is documented as working in Bavaria in the Castle of Nymphenburg (1719); in the castle of Schleissheim (1725–1729); and in the Benedictine abbey of Ottobeuren. He returned to Venice in 1726. His Arraignment of Paris hangs in the Villa Pisani at Stra. From 1730 to 1739 he worked in England, in Pown House, Moor Park Wolterton Hall and in the Theatre of Covent Garden. From there, he helped convince Canaletto to travel to England by telling him of the ample patronage available.
From his travel to Paris in 1736, he met the celebrated castrato Farinelli. Later in Madrid, he was to paint a self-portrait with the singer and entourage. He also encountered the painting of François Lemoyne and Boucher.
In 1739 he returned to Italy, perhaps to Naples and surely to Montecassino, in whose Abbey existed two canvases (destroyed during World War II). Until 1747, he travelled to Venice to paint for Sigismund Streit, for the Casa Savoia and other buildings of the city. In 1747 he left Italy and established himself in Madrid. There he became court Painter to Ferdinand VI of Spain and Director of the Royal Academy of Saint Fernando. He died in Madrid.
