The situation changed around 1740. The lucrative tourist market collapsed as a result of the outbreak of war throughout Europe. Smith continued his efforts to help Canaletto secure commissions for idealized views in a classical style and also published a series of etchings of capriccios, but the returns were not high enough. In 1746 Canaletto left for his clients' homeland, England.
