Antonine Itinerary

Below are the original Latin ablative forms for sites along route 13,[3] followed by a translation with a possible (but not necessarily authoritative) name for the modern sites.[4] A transcriber omitted an entry, so that the total number of paces did not equal the sum of paces between locations.

De Situ Britanniae (made available c. 1749, published 1757) was a forgery that provided much spurious information on Roman Britain, including "itineraries" that overlapped the legitimate Antonine Itineraries, sometimes with contradicting information. Its authenticity was not seriously challenged until 1845, and it was still cited as an authoritative source until the late nineteenth century. By then, its false data had infected almost every account of ancient British history, and had been adopted into the Ordnance Survey maps,[6] as General Roy and his successors believed it to be a legitimate source of information, on a par with the Antonine Itineraries. While the document is no longer cited since its authenticity became indefensible, its data has not been systematically removed from past and present works.

Some authors, such as Thomas Reynolds, without challenging the authenticity of the forgery, took care to note its discrepancies and challenge the quality of its information.[7][8] This was not always so, even after the forgery was debunked.

Gonzalo Arias (died 2008) proposed that some of the distance anomalies in the British section of the Antonine Itinerary resulted from the loss of Latin grammatical endings, as these had marked junctions heading towards places, as distinct from the places themselves.[9] However, Arias may not have taken account of earlier work indicating that distances were measured between the edges of administrative areas of named settlements as opposed to centre-to-centre, thereby explaining supposed distance shortfalls and providing additional useful data on the approximate sizes of such areas.[10]
