The first two columns of the table below show route Iter XV in the Antonine Itinerary.
Based on the interpretations of the placenames as given in column three, it appears to be the most corrupted of the routes. For example, the total distance is said to be 136 (cxxxvi) miles whereas the distances between the modern places names add up to 126. However, with the addition of three stations, shown in red in the table below, the distances in the document can no longer be considered as largely erroneous bearing in mind that they are rounded to the nearest Roman mile.
|Iter XV||Roman miles
||Statute miles||Location||Location distance
|unknown name||3||2.8||Devil’s Ditch||3.2||-0.4|
|Venta Velgarum||21||19.3||Old Sarum||18.9||0.4|
Col. 1: Itinerary name.
Col. 2: Itinerary distance in Roman miles given in Hindu-Arabic numerals.
Col. 3: Itinerary distance converted into statute miles.
Col. 4: Modern name for the suggested location.
Col. 5: Distance to the suggested location in statute miles.
Col. 6: Discrepancy between the itinerary and location distances in statute miles.
Note, the distance from Silchester to Exeter is now 141 (cxxxxi) Roman miles. This would suggest that the AI cxxxvi was the result of the final x being misread as a v. A major reinterpretation is of Venta Velgarum being identified with Salisbury instead of Winchester. Sorbiodoni is Badbury Rings, the site of the battle of Badon, see Badbury Rings. The name possibly is a derivation of Caer Vadon. Vindocladia’s identification with Weatherby Castle gains support from its description on Pastscape:
“The earthwork remains of Weatherby Castle, a small multivallate hillfort comprising two roughly concentric ramparts and ditches, which enclose an irregular area on the highest part of a chalk spur.”
3.1 statute miles from Weatherby Castle is Winterborne Whitechurch a name which seems to contain the component Vindo-. Muriduno is located at Sidford with the nearby harbour at the mouth of the River Sid.
