Looking round the room, after Rubens has been dismissed, it is too evident that the best of the Uffizi collection is behind us. There are interesting portraits here, but biographically rather than artistically. Here are one or two fine Sustermans' (1597-1681), that imported painter whom we shall find in such rare form at the Pitti. Here, for example, is Ferdinand II, who did so much for the Uffizi and so little for Galileo; and his cousin and wife Vittoria della Rovere, daughter of Claudia de' Medici (whose portrait, No. 763, is on the easel), and Federigo della Rovere, Duke of Urbino. This silly, plump lady had been married at the age of fourteen, and she brought her husband a little money and many pictures from Urbino, notably those delightful portraits of an earlier Duke and Duchess of Urbino by Piero della Francesca, and also the two Titian "Venuses" in the Tribuna. Ferdinand II and his Grand Duchess were on bad terms for most of their lives, and she behaved foolishly, and brought up her son Cosimo III foolishly, and altogether was a misfortune to Florence. Sustermans the painter she held in the highest esteem, and in return he painted her not only as herself but in various unlikely characters, among them a Vestal Virgin and even the Madonna. Here also is No. 196, Van Dyck's portrait of Margherita of Lorraine, whose daughter became Cosimo III's wife--a mischievous, weak face but magnificently painted; and No. 1536, a vividly-painted elderly widow by Jordaens (1593-1678); and on each side of the outrageous Rubens a distinguished Dutch gentleman and lady by the placid, refined Mierevelt.
