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 ) .
