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
