Peter Bell the Third by Percy Bysshe Shelley

Peter Bells, one, two and three, / O'er the wide world wandering be. - / First, the antenatal Peter, / Wrapped in weeds of the same metre, / The so-long-predestined raiment / Clothed in which to walk his way meant / The second Peter; whose ambition / Is to link the proposition, / As the mean of two extremes- / (This was learned from Aldric's themes) / Shielding from the guilt of schism / The orthodoxal syllogism; / The First Peter-he who was / Like the shadow in the glass / Of the second, yet unripe, / His substantial antitype. -

Then came Peter Bell the Second, / Who henceforward must be reckoned / The body of a double soul, / And that portion of the whole / Without which the rest would seem / Ends of a disjointed dream. - / And the Third is he who has / O'er the grave been forced to pass / To the other side, which is,- / Go and try else,-just like this.
