Dürer's best known individual engravings (that is, ones that are not part of a series) include ' (1513), ' (1514) and "Melencolia I" (1514). His most iconic images are his woodcuts of the "" (1497–1498) from the "Apocalypse" series, the "Rhinoceros", and numerous self-portraits in oils. Dürer possibly did not cut his own woodblocks but may have employed a skilled carver who followed his drawings faithfully. He painted a number of religious works in oils and made many brilliant watercolours and drawings, which through modern reproductions are now perhaps his best known works.
