The story of the greatest map-maker of all time.

Until Mercator's Projection, maps offered a pictorial encyclopaedia to an illiterate world, and that world stretched far beyond the knowledge and travels of most mapmakers. It is this evolution of mapmaking from art to science that forms the backdrop to the story of Mercator, from the days of Herodotus and Strabo when fabulous creatures were supposed to inhabit the fringes of the world to the great mappae mundi of Hereford and Ebsdorf. The Greek geographer Pytheas claimed to have visited the far north of Britain to establish the limits of the habitable world; but further north, he claimed that the earth, air and sea coalesced into a jellyfish-like gelatinous suspension which made life impossible. Mercator promises to be a brilliantly readable and absolutely fascinating history for the general reader, describing as it does how our world-view came into being.
