Early though the lau rel grows, it withers quicker than a rose. Now you will not swell the rout of lads that wore their h o nours out. Runners whom renown outran and the name died before the man. And round that early lau relled head will flock to gaze the strengthless dead, and find unwithered on its cur ls, a garland briefer than a girl's.
