This is the seventh volume in the series Drawings in Swedish Public Collections and the third devoted to Italian drawings. It is primarily concerned with a collection of 83 drawings from the 15th century emanating, partly or wholly, from the famous collection which was built up by Giorgio Vasari during the decades round about the mid-16th century and which came to Nationalmuseum through Pierre Crozat and Carl Gustaf Tessin. Although a great deal has been published about it, much of this material has given rise to a century of perplexity and dispute. By reason of its beauty and the complexity of its historical role, the collection occupies a position all of its own among the treasures of Nationalmuseum.
