The earliest forms of illustration were prehistoric cave paintings. Before the invention of the printing press, books were hand-illustrated. Illustration has been used in China and Japan since the 8th century, traditionally by creating woodcuts to accompany writing.15th century through 18th century
During the 15th century, books illustrated with woodcut illustrations became available. The main processes used for reproduction of illustrations during the 16th and 17th centuries were engraving and etching. At the end of the 18th century, lithography allowed even better illustrations to be reproduced. The most notable illustrator of this epoch was William Blake who rendered his illustrations in the medium of relief etching.Illustration by Santiago Martinez Delgado.
