Sleep! Cast thy canopy Over this sleeper's brain, Dim grow his memory, When he wake again. Love stays a summer night, Till lights of morning come; Then takes her winged flight Back to her starry home. Sleep! Yet thy days are mine; Love's seal is over thee: Far though my ways from thine, Dim though thy memory. Love stays a summer night, Till lights of morning come; Then takes her winged flight Back to her starry home.
