Giorgio Giulio Clovio or Juraj Julije Klović (1498 – 5 January 1578) was a Croatian-Italian illuminator, miniaturist, and painter born in the Kingdom of Croatia, who was mostly active in Renaissance Italy. He is considered the greatest illuminator of the Italian High Renaissance, and arguably the last very notable artist in the long tradition of the illuminated manuscript, before some modern revivals.
