Giovanni Benedetto Castiglione (1609 – 1664) was an Italian Baroque artist, painter, printmaker and draftsman, of the Genoese school. He is best known now for his elaborate engravings, and as the inventor of the printmaking technique of monotyping. Castiglione painted portraits, historical pieces and landscapes, but chiefly excelled in fairs, markets and rural scenes with animals. Noah's ark and the animals entering the Ark was a favorite subject of his. His paintings are to be found in Rome, Venice, Naples, Florence, and more especially Genoa and Mantua. The Presepio (Nativity of Jesus) for the church of San Luca, Genoa, ranks among his most celebrated paintings. He painted a Mary Magdalene and Catharine for the church of the Madonna di Castello and St. James defeats the Moors for the Oratorio di San Giacomo della Marina, both in Genoa.
Castiglione was a brilliant draftsman and pioneered the development of the oil sketch (often using a mixture of mediums) as a finished work - previously they had been used only for working studies for another finished piece, for example by Rubens. He returned to the same subjects over and over again, but with significantly different compositions each time. He also executed a number of etchings.
