It is a reunion the likes of which neither you nor your progeny of several generations are likely to see again: a cycle of paintings by Renaissance master Titian commissioned by Prince, then King, Philip II of Spain on themes drawn from antiquity via Ovid. One of these is a central canvas in the collection of the Isabella Stewart Gardner Museum, The Rape of Europa, freshly emerged from a year of conservation by the Gardner’s own Gianfranco Pocobene.

The other five paintings are the Danaë from the Wellington Collection at Apsley House in London, Venus and Adonis from the Prado in Madrid, Perseus and Andromeda from the Wallace Collection in London, and Diana and Actaeon and Diana and Callisto from the National Galleries of Scotland in Edinburgh. (All were painted in the 1550s or thereabouts.)
