Captain Ahab had a bit of an obsession with the white whale named Moby Dick:
"I'll chase him round Good Hope, and round the Horn, and round the Norway Maelstrom, and round perdition's flames before I give him up."
"To the last I grapple with thee; from hell's heart I stab at thee; for hate's sake I spit my last breath at thee."
(Ishmael) And he piled upon the whale's white hump a sum of all the rage and hate felt by his own race. If his chest had been a canon, he would have shot his heart upon it.
