Tiziano Vecellio, also known as Titian, was the greatest Venetian artist of the 16th century. Titian is known primarily for mastering the use of color and his versatility – he was equally adept at painting portraits, landscapes and mythological and religious subjects. As a teenager, he worked with prominent Venetian artists such as Giorgione and Giovanni Bellini before going out on his own. He was soon painting for royalty from all over Europe, including King Philip II of Spain. Titian painted portraits of many leading figures over his career, from Pope Paul III to Holy Roman Emperor Charles V.
