St Catherine of Siena, Giovanni Marco Pitteri, after Giovanni Battista Tiepolo, c. 1750
Giambattista Tiepolo’ sons reproduced many of their father’s works in print. Perhaps this is why there are so few prints of his paintings by professional engravers. A stunning example is this virtuoso, hyper-realistic ‘portrait’ of Catherine of Siena. This 14th-century mystic identified with the suffering of the crucified Christ to such an extent that she received stigmata, wounds in her hands, in a vision.
