This paper considers the circumstantial evidence for a Mappa Mundi of Roman origin and introduces a methodology for examining that possibility. Julius Caesar (100-44BC) ordered that a world survey be carried out to establish the extent of the Roman Empire and perhaps the adjoining lands which as then had not been conquered. Following the commencement of a new era, BC/AD we find cartographers such as Marinus of Tyre and Claudius Ptolemy producing quite remarkable maps, with for the era an un-paralleled accuracy. Although evidence of the Roman survey is limited, it can only be from official Roman sources that those two cartographers received their latest data. Thus by analysing the works of authorities who succeeded the Romans, such as the Early Christian Church, we can perhaps establish the veracity of the historical texts. Fortunately, those works can be examined by a study of a landscape phenomenon which can only exist because there was a map of sufficient quality and accuracy to allow the concept discovered to be formed. By studying the positions in the landscape of Early Christian edifices of a particular nature, noting the methodology and metrology used, it is possible to conclude that there was a Roman Mappa Mundi dating to the BC/AD interface.

ABSTRACT
The Gough map stands alone as a work of immense clarity. But, it is an enigma which requires examination to enable a comprehension of the knowledge available to the original mapmaker. The scale and relative disposition of geographical features must be known, but, apparently any such data normally appended to a map, such as guidance lines (if they were ever drawn) are missing. This may be a simple omission due to a later cutting of the map base skins.
Previous investigations of the map fundamentals have indicated accuracy in the overall concept and dated the map to c1360AD. This paper considers just how the data to draw such a map may have been collated, how it was drawn and the basic parameters underlying its construction. The conclusion is that a paradigm shift in our thoughts is required concerning the availability of ancient data.

There is a surprising amount of geographical information in the early texts; both Roman Latin and British Latin, which if analyzed indicate a changing description of Britannia. That change is from a Triangular shape to a Rectangle. Why?
These two shapes are hardly compatible. Thus this speculative paper is a hypothesis on the reasons for the change, its basis in fact, and its record in the early maps.
It is also one of three texts which combine to explain the early map history of Britannia.

Variously praised as, ‘the most important medieval map of Britain’, or ‘the earliest surviving map to show the island of Britain in a geographically recognisable form’, and ‘the oldest surviving road map of Great Britain’, the Gough map has been the subject of much scrutiny over the years. But no researcher appears to have dissected the map, deduced its foundations and then endeavoured to redraw it, metaphorically and physically, to prove their findings. This paper reports on such an attempt and the surprising results.
