The Language of Line is a practical, engaging treatise on the practice of drawing. It shows us how to look at a drawing as a whole and in its details and learn how to appreciate what its author wants to convey. Eric Hebborn's posthumous book is his most important to date. This manuscript, discovered among his various papers and documents, puts forward Hebborn's claims that a common denominator exists between all really good drawings, independent of time and place and even the artists who produced them. Hebborn spent his life studying the works of the Old Masters and gained worldwide recognition for his ability to draw in the style of Michelangelo, Rembrandt, van Dyck, Piranesi, Breughel, Gainsborough and many others. Hebborn's innovative way of studying drawings brings us closer to a real understanding of how the combination of strokes used by the great masters defined their particular styles. The Language of Line not only explains the fundamental elements of line drawing but also serves as a useful tool for teachers who want to develop their students' appreciation of various types of drawings and artistic compositions.
