His whole high, broad form, seemed made of solid bronze, and shaped in an unalterable mould, like Cellini's cast Perseus. Threading its way out from among his grey hairs, and continuing right down one side of his tawny scorched face and neck, till it disappeared in his clothing, you saw a slender rod-like mark, lividly whitish. It resembled that perpendicular seam sometimes made in the straight, lofty trunk of a great tree, when the upper lightning tearingly darts down it, and without wrenching a single twig, peels and grooves out the bark from top to bottom ere running off into the soil, leaving the tree still greenly alive, but branded. Whether that mark was born with him, or whether it was the scar left by some desperate wound, no one could certainly say. By some tacit consent, throughout the voyage little or no allusion was made to it, especially by the mates. But once Tashtego's senior, an old Gay-Head Indian among the crew, superstitiously asserted that not till he was full forty years old did Ahab become that way branded, and then it came upon him, not in the fury of any mortal fray, but in an elemental strife at sea. Yet, this wild hint seemed inferentially negatived, by what a grey Manxman insinuated, an old sepulchral man, who, having never before sailed out of Nantucket, had never ere this laid eye upon wild Ahab.
