Blue whale skeleton at New Bedford museum still oozing oil

You have to see those whales skeletons in person to understand their sheer size. And if you want to know more than you need to about whales, pick up a copy of Moby Dick. Don't be intimidated by the size. I still can't believe this book was written in the 1800s. Catching a whale was akin to striking oil.

The Basque History of the World by Mark Kurlansky (book/audiobook) is excellent on this topic. The Basque, according to current evidence, invented whaling, and were culturally central to its interweaving with human history. The book tells the tale with rigour and flare.
