Titian's Diana and Callisto (1556-1559). The pregnancy of Callisto, an attendant nymph of Diana, goddess of the moon, hunting and chastity, is cruelly revealed. Banished by Diana, Callisto was later transformed by Jupiter her seducer, into the constellation of the Great Bear. The powerful gestures and varied poses of Diana and her nymphs complement those in the composition of the companion painting Diana and Actaeon. These large so-called 'poesie' reveal Titian's mastery of the idealised human figure and of colour and light to convey contrasting textures. As late works, they also indicate the remarkable physical energy he expended using his fingers as much as his brushes to apply paint. Here, as in most subsequent depictions, Diana points angrily, as Callisto is held by two nymphs, who may be pulling off what little clothing remains on her.
