available to reach any degree of certainty, and the locations suggested are little more than guesswork. Reflecting the lack of evidence, there is little agreement on assigning modern locations to the towns. Among the assignments made by those whose work is considered to be authoritative (to varying degrees) are those of William Baxter (1719, Glossarium Antiquitatum Britannicum), William Camden (1607, Britannia), John Horsley (1732, Britannia Romana), William Forbes Skene (1880, Celtic Scotland, a History of Ancient Alban), George Chalmers (c. 1820, Caledonia), and William Roy (1793, Military Antiquities of the Romans in Britain). Other historians either quote one of these as the authority for assigning locations to Ptolemy's towns, or simply assert a location in passing. A few offer lists of the assertions of the above authorities. Alauna is suggested to be the Camelon that is near and to the west of Falkirk, or at Stirling, or Kier (about NNW of Stirling, on the Allan Water), or the island of Inchkeith. Colania is suggested to be Lanark or Carstairs (about NE of Lanark), or some other place on the east side of Clydesdale. Coria is suggested to be Lynekirk (about WNW of Peebles, or some other place on the east side of Clydesdale. Lindum is suggested to be Kirkintilloch (about NE of Glasgow), or Linlithgow, or near Ardoch (the one about NNW of Stirling). Victoria is suggested to be Dalginross (about W of Crieff, or Abernethy (about SE of Perth). Vanduara is suggested to be Paisley or Renfrew (both about to the west of Glasgow), or some 20 miles south of Glasgow at Loudoun Hill. From 1757, initial studies of the Damnonii were heavily influenced by the literary forgery The Description of Britain (De Situ Britanniae). The work was considered the only authoritative record of Britannia Inferior, the northern part of Roman Britain. Throughout the latter part of the 18th century until it was debunked as a forgery in 1845, it purportedly contained a lost contemporary account of the province of Britannia from a Roman general, new details about Roman roads in Britain in the style of the Antonine Itinerary, and an improved version of Ptolemy's map. Its credibility was such, that even after it was proven to be fake, it was still cited as a historical source until the end of the 19th century. Even Chalmers and Roy believed in its authenticity at the time they wrote. De Situ
