From the ancient pages of the Old Norse Edda to the interwar pages of American adventure magazines, the depths of our oceans have, in imagination, been host to unspeakable monsters for many hundreds of years. In modern times, the phrase “Here Be Dragons” has been absorbed into popular culture as titles for books, films, TV shows, bands and video games, all this despite the fact that it only ever appeared on the unknown seas of a single 16th Century Globe. Far more common were the giant sea monsters that adorned maps for hundreds of years, existing only as illustrations and in the minds of those that viewed them. In the summer of 1817, just off the coast of Massachusetts, however, these illustrations became flesh and blood for several weeks when witnesses of a Giant Sea Serpent numbered into the hundreds, in what the 19th Century Harvard Professor Jacob Bigelow called “the most interesting problem in the science of natural history.” SOURCES France, Robert L.
