While all these advances were being made, the art of portraiture had not stood still. Its popularity had only increased as the years went on. Titian was too busy with commissions for foreign princes to supply the great demand there was in Venice alone. Tintoretto painted portraits not only with much of the air of good breeding of Titian's likenesses, but with even greater splendour, and with an astonishing rapidity of execution. The Venetian portrait, it will be remembered, was expected to be more than a likeness.
