Literature: Evelyn Dunbar: A Life in Painting, Christopher Campbell-Howes, October 2016, pages 355/6. The unknown location of the finished version of the artist’s cartographic allegory Mercatora is a major gap in Dunbar studies. She called it Mercatora after Gerardus Mercator, the famous 16th century cartographer, still remembered for the famous Mercator’s Projection with its still used representation of the spherical Earth as a rectangle. In this study Dunbar is exploring how best to symbolise the cartographer’s eternal problem of the transfer of the three-dimensional spherical shape of the earth to the two-dimensional rectangular map.The irregular shapes at the foot may represent distorted tracings.
