Time, Real and Imaginary

by Samuel Taylor Coleridge

On the wide level of a mountain's head, (I knew not where, but 'twas some faery place) Their pinions, ostrich-like, for sails out-spread, Two lovely children run an endless race, A sister and a brother ! This far outstripp'd the other ; Yet ever runs she with reverted face, And looks and listens for the boy behind : For he, alas ! is blind ! O'er rough and smooth with even step he passed, And knows not whether he be first or last.
