Went to the British Library Map Room today to view Tharp's Physiographic diagram of the South Atlantic Ocean, the Caribbean Sea, the Scotia Sea, and the eastern margin of the South Pacific Ocean. It is always a thrilling moment when you are handed a carefully packaged document, that may not have been viewed for many years, from the BL’s collections . Even so spreading the map out on the table was a revelation, what emerged, fold by fold, was a richly detailed drawing of the seabed which I spent a good hour pouring over, as much for the sensual and aesthetic experience of doing so, than anything else. The drawings of seamounts, of which an estimated 30,000.00 cover the globe, resemble maps of Tolkein's Middle earth.
I have discovered that a number of Tharp maps are held in different libraries throughout the UK, including the V and A and the Maritime Museum, suggesting the possibility of a Tharp pilgrimage to view all of them. NOCS have one of the North Atlantic, which I shall investigate on my next trip there.
