Over the past few years, curator and Dürer specialist Christof Metzger has been re-evaluated the ALBERTINA's collection, the world’s most important one on both Dürer's drawings and watercolours. The most surprising outcomes of this work are his thoughts on the great studies of nature from the first years of 16th century - such as the Hare and the Large Piece of Turf - and the chiaroscuro studies on colored paper such as the famous Praying Hands, all of which push the limits of what can be accomplished by pen and brush.
