They probably all contributed as a team to some of the larger commissions later attributed to his brother Francesco Guardi. His sister Maria Cecilia married the pre-eminent Veneto-European painter of his epoch, Giovanni Battista Tiepolo. He may have received his artistic training in Vienna, where he is first recorded in 1719, but had established a workshop in Venice by 1730. Among his first important clients was the connoisseur and collector Johann Matthias von der Schulenburg, for whom Guardi created numerous paintings with an Orientalist theme.
