Original: However, in 1513 and 1514 Dürer created his three most famous engravings: The Knight, Death, and the Devil (1513, probably based on Erasmus's treatise 'Enichiridion militis Christiani'), St. Jerome in his Study, and the much-debated Melencolia I (both 1514).
Simplified: Dürer's best known individual engravings (that is, ones that are not part of a series) include Knight, Death, and the Devil (1513), Saint Jerome in his Study (1514) and Melencolia I (1514).
