Although now long estranged,Man is not wholly lost nor wholly changed.Dis-graced he may be, yet is not de-throned,and keeps the rags of lordship once he owned:Man, Sub-creator, the refracted Lightthrough whom is splintered from a single Whiteto many hues, and endlessly combinedin living shapes that move from mind to mind.Though all the crannies of the world we filledwith Elves and Goblins, though we dared to buildGods and their houses out of dark and light,and sowed the seed of dragons- 'twas our right(used or misused). That right has not decayed:we make still by the law in which we're made.Fantasy remains a human right: we make in our measure and in our derivative mode, because we are made: and not only made, but made in the image and likeness of a Maker.
