Sculpture Portraits

One of the best-known portraits in the Western world is Leonardo da Vinci's painting titled Mona Lisa, which is a painting of an unidentified woman. The world's oldest known portrait was found in 2006 in the Vilhonneur grotto near Angoulême and is thought to be 27,000 years old.
Self-portraiture
When the artist creates a portrait of him- or herself, it is called a self-portrait. Identifiable examples become numerous in the late Middle Ages, but if the definition is extended the first was by the Egyptian Pharaoh Akhenaten's sculptor Bak, who carved a representation of himself and his wife Taheri c. 1365 BC. However, it seems likely that self-portraits go back to the earliest representational art, and literature records several classical examples, now lost.
