"Sebastiano Ricci enjoyed an international reputation. He worked all over Italy, Austria and France and, from 1712-1716, in England, mainly painting walls and ceilings with decorative schemes. His patrons included Queen Anne and Lord Burlington. Ricci, described by an English contemporary as ""a lusty man, inclinable to fat"", is said to have left England in disgust when the commission to decorate St. Paul's was given to James Thornhill, a native Protestant.
