This project aims to examine the historical source that mappa mundi is. The project is based on a literature study of primarily four carefully chosen writers. The writers are respectively historian of cartography David Woodward, Professor of Renaissance Jerry Brotton, Professor of History Evelyn Edson and Art Historian Naomi Reed Kline. The project is based on a variety of topics through which the use of the Hereford map as a historian source is highlighted and discussed. The premise of the study is a critical position in relation to the conclusions drawn by the chosen authors. The intention is to challenge the inferences made to reality. The conclusion of this report is that interpretations are based on the respective methods and their various viewpoints.
