The lyf so short, the craft so longe to lerne. Th' assay so hard, so sharp the conquerynge, The dredful joye, alwey that slit so yerne Al this mene I be love... For out of olde feldes, as men seith, Cometh al this new corn fro yeer to yere And out of olde bokes, in good feith, Cometh al this newe science that men lere.
Geoffrey Chaucer
