Who or what is Bob Dylan?

Who or what is Bob Dylan? Ghost? Man? Ghost of a Man? Elfin figure with pointed boots, bent knee and raised foot? Little drummer boy with striped pants and marching tunic? Chorister? Conductor whose gentle hand commands a wall of sound? Rider of the Easter Moon tides? Force who steps through the ordinary world bringing a spirit that is not stopped by any of the foibles of time, place and land? Don Quixote and the wind mills? Is it a child or an old man under the firmly fitting white Fedora hat? Who will emerge with each song?
