Titian's Mistress

Titian's Mistress, also known as An Unknown Lady, is an oil painting variously attributed to Titian, his workshop, or both. It was painted in about 1550 or 1560. The painting is part of the Wellington Collection at Apsley House in London.

Prints
There is a print by Lucas Vorsterman II, dated 1640–1666, after the painting by Titian in Apsley House. A painted copy of the Titian is mentioned in Rubens' house inventory of 1640, and may be the source of the print. A print by Sir Anthony van Dyck, also entitled Titian's Mistress, is unrelated to the paintings.
