He had been originally nurtured among the crazy society of Neskyeuna Shakers, where he had been a great prophet; in their cracked, secret meetings having several times descended from heaven by the way of a trapdoor, announcing the speedy opening of the seventh vial, which he carried in his vest-pocket; but, which, instead of containing gunpowder, was supposed to be charged with laudanum.  A strange, apostolic whim having seized him, he had left Neskyeuna for Nantucket, where, with that cunning peculiar to craziness, he assumed a steady, common sense exterior, and offered himself as a green-hand candidate for the Jeroboam’s whaling voyage.  They engaged him; but straightway upon the ship’s getting out of sight of land, his insanity broke out in a freshet.  He announced himself as the archangel Gabriel, and commanded the captain to jump overboard.  He published his manifesto, whereby he set himself forth as the deliverer of the isles of the sea and vicar-general of all Oceanica.  The unflinching earnestness with which he declared these things;—­the dark, daring play of his sleepless, excited imagination, and all the preternatural terrors of real delirium, united to invest this Gabriel in the minds of the majority of the ignorant crew, with an atmosphere of sacredness.  Moreover, they were afraid of him.  As such a man, however, was not of much practical use in the ship, especially as he refused to work except when he pleased, the incredulous captain would fain have been rid of him; but apprised that that individual’s intention was to land him in the first convenient port, the archangel forthwith opened all his seals and vials—­devoting the ship and all hands to unconditional perdition, in case this intention was carried out.  So strongly did he work upon his disciples among the crew, that at last in a body they went to the captain and told him if Gabriel was sent from the ship, not a man of them would remain.  He was therefore forced to relinquish his plan.  Nor would they permit Gabriel to be any way maltreated, say or do what he would; so that it came to pass that Gabriel had the complete freedom of the ship.  The consequence of all this was, that the archangel cared little or nothing for the captain and mates; and since the epidemic had broken out, he carried a higher hand than ever; declaring that the plague, as he called it, was at his sole command; nor should it be stayed but according to his good pleasure.  The sailors, mostly poor devils, cringed, and some of them fawned before him; in obedience to his instructions, sometimes rendering him personal homage, as to a god.  Such things may seem incredible; but, however wondrous, they are true.  Nor is the history of fanatics half so striking in respect to the measureless self-deception of the fanatic himself, as his measureless power of deceiving and bedevilling so many others.  But it is time to return to the Pequod.

“I fear not thy epidemic, man,” said Ahab from the bulwarks, to Captain Mayhew, who stood in the boat’s stern; “come on board.”
