Giovanni Antonio Canal (18 October 1697 – 19 April 1768), commonly known as Canaletto (kanaˈletto), was an Italian painter from the Republic of Venice, considered an important member of the 18th-century Venetian school.
Painter of city views or vedute, of Venice, Rome, and London, he also painted imaginary views (referred to as capricci), although the demarcation in his works between the real and the imaginary is never quite clearcut. He was further an important printmaker using the etching technique. In the period from 1746 to 1756, he worked in England, where he painted many views of London and other sites, including Warwick Castle and Alnwick Castle. He was highly successful in England, thanks to the British merchant and connoisseur Joseph "Consul" Smith, whose large collection of Canaletto's works was sold to King George III in 1762.
He was born in Venice as the son of the painter Bernardo Canal, hence his mononym Canaletto ("little Canal"), and Artemisia Barbieri. Canaletto served an apprenticeship with his father and his brother of a theatrical scene painter. In 1718, having already taken part in designing sets for operas by Fortunato Chelleri, Giovanni Porto and Antonio Vivaldi, Canaletto travelled to Rome. During his time in Rome, he worked with his father producing the scenery for two operas by the composer Alessandro Scarlatti, Tito Sempronio Greco and Turno Aricino which were performed at the Teatro Catranica during the carnival season of 1720.
Canaletto was inspired by the Roman vedutista Giovanni Paolo Pannini, and started painting the daily life of the city and its people.
After returning from Rome in 1719, he began painting in his topographical style. His first known signed and dated work is Architectural Capriccio (1723, Milan, in a private collection). Studying with the older Luca Carlevarijs, a well-regarded painter of urban cityscapes, he rapidly became his master's equal.
In 1725, the painter Alessandro Marchesini, who was also the buyer for the Lucchese art collector Stefano Conti, had inquired about buying two more 'views of Venice', when the agent urged him to consider instead the work of "Antonio Canale.
