Rococo painter ‘Chevalier’ Andrea Casali was born on 17 November 1705 in Rome. Early in his career he worked as a decorative painter in Roman churches. His contact with British patrons began in Rome, where in 1738 he painted the portrait of Charles Frederick who encouraged him to come to England.
Casali arrived in London in 1741, after spending some eight months in Paris. In 1743 he was working at Wanstead House, Essex, where Lord Castlemaine commissioned a set of six history pictures. He exhibited regularly at the Free Society and Society of Artists (where his address is given as being as Gerrard Street in the exhibition catalogues), and undertook a number of decorative commissions. His most substantial patrons were Thomas Coke, Earl of Leicester, and Alderman William Beckford. He returned to Rome in 1766 where he died in 1784.
