Diego Velazquez

Diego Rodríguez de Silva y Velázquez (June 6, 1599 – August 6, 1660), commonly referred to as Diego Velázquez, was a Spanish painter who was the leading artist in the court of King Philip IV. He was an individualistic artist of the contemporary baroque period, important as a portrait artist. In addition to numerous renditions of scenes of historical and cultural significance, he painted scores of portraits of the Spanish royal family, other notable European figures, and commoners, culminating in the production of his masterpiece Las Meninas (1656).
