"That infancy looketh forward and age backward; was it not that which Janus his double visage signified? yeares entraine me if they please: but backward. As far as mine eyes can discerne that faire expired season, by fits I turne them thitherward" (The Essayes of Lord Michaell de Montaigne, John Florio (trans.), 1603).
