Marieschi was born in Venice and was a well known architectural painter of Venetian subjects and views. He was a pupil of his father, Michele Marieschi, and Gasparo Diziani, also Venetian “view” painters.
He imitated the style of the Italian painter Canaletto who devoted himself to painting picturesque views of Venice's canals, bridges, palaces and churches. During the eighteenth century paintings of the Doge’s Palace were popular "souvenirs" of visits purchased by those on the Grand Tour.
