The reputation of pastels, invented in France and in Italy in the 15th century, benefited from the works of one peerless exponent: Leonardo da Vinci. Pastel drawing reached its highest form in the 18th century with the work of Quentin de La Tour, the undisputed master of the art. It then waned shortly after the French revolution, with the rise of neo-classicism and oil painting. As for the charcoal pencil, it is the simplest and most commonly used tool in art drawing, studies and sketches. Pebeo pastels and charcoals provide high quality materials for drawing and painting.
