Artists could now have a successful career painting portraits, landscapes, still lifes or other genre specialisms, without ever painting a religious subject – something unusual hitherto unusual in the Catholic countries, though long the norm in Protestant ones. The number of sales of paintings, metalwork and other church fittings to private collectors increased during the century, especially in Italy, where the Grand Tour gave rise to networks of dealers and agents. Leonardo da Vinci's London Virgin of the Rocks was sold to the Scottish artist and dealer Gavin Hamilton by the church in Milan that it was painted for in about 1781; the version in the Louvre having apparently been diverted from the same church three centuries earlier by Leonardo himself, to go to the King of France.
