Lines of Thought uncovers the process and practice of drawing, illustrated by a selection of work created over 500 years. From Dürer to Degas, Michelangelo to Matisse, Rembrandt to Riley, this publication studies the types of thinking that produced their drawings--brainstorming, inquiry, experiment, association, development and decision--giving us fresh insight into the creative impulse of some of the world's greatest artists.The accompanying exhibition will tour the United States in 2017 and 2018, inspiring and encouraging the practice of drawing. The exhibition and the book feature highlights of the British Museum's outstanding Prints and Drawings Collection.
