I read Moby Dick once or twice in school. I didn't mind the academic interpretion. The non-fiction about the whaling industry in the Nineteenth Century was fascinating enough to carry the day for my reading. But then I read it later on my own, and it was a whole new book. I had no recollection of the humor. Melville is wry and droll and almost Monty Python in places. That I had missed that on the first readings seemed unlikely, but it was true. The allegorical dimensions are still there, but so is the schtick.
At the time, when Melville was at sea, big whaling was like big oil today, a cut-throat corporate money maker that was a huge revenue stream that used people up relentlessly.
