Caesar van Everdingen was one of the few artists to paint the rape of Europa from the point of view of the shore, of her companions, who are thus much more prominent than Europa herself. He never sold the painting in his lifetime. You can find more details about it here and here.

Vertumnus was a Roman garden god, probably of Etruscan origin, with no Greek equivalent. He could change his form at will. Pomona was a wood nymph, a goddess of fruitful abundance, she too without a Greek counterpart. Together they had a festival on August 13th, the Vertumnalia.

In book XIV of his Metamorphoses, Ovid tells the story how Vertumnus gained entry to Pomona’s orchard by disguising himself as an old woman. Then he seduced her by telling her the story of Anaxarete, who refused the advances of a shepherd named Iphis, remained unmoved even when he hanged himself on her doorpost and was turned into a stone statue for her cruelty.

The story of Vertumnus and Pomona thus gave an artist the opportunity to paint an old and a young woman together, if he wanted. Not all did. Those that did were remarkably often from the Netherlands, as in this case Caesar van Everdingen, who made another painting on the same subject later.

Caesar van Everdingen: Still-Life with a Bust of Venus, 1665, at the Mauritshuis in The Hague. It is a pendant to Trompe-l’oeil with a Bust of Adonis, which is in a different place (The Old Town House, Cape Town, Michaelis Collection), and of which unfortunately no high-resolution reproduction exists.
