Attested: Galluvio seems like the best spelling to take from the juxtaposed handwritten lower-case letters in RC's 3 manuscripts, as discussed here.
Where: RC lists Galluvio between Lancaster and Kendal, so the logical area to look is close to the line of the modern M6 motorway between Carnforth, Lancashire, near the river Keer, and Hincaster, Cumbria, near the river Kent. There is no recognised Roman-era settlement or fort on this line, but a recent Lidar survey has stressed the size of the hillfort on Warton Crag, at SD491727. Preferring this site to the Burrow-in-Lonsdale (Galacum) Roman fort rests upon the weak argument of which one would make RC's track straighter.
Name Origin: In RC Galluvio is immediately preceded by Caluvio, which fits with Lancaster and can be explained as ‘sea of reeds’. It is marginally preferable to explain Galluvio as a topographically similar place (regardless of which of the river mouths opening into the wide expanse of Morecambe Bay it was) than to suggest that a scribe was fooled into miscopying Galacum. The world is full of pairs of nearby place names that are confusably similar, which sometimes share a geographical characteristic that is more or less well understood (think of Upton, Berwick, Kirkby, Glasson) and sometimes arise from distinct names evolving to sound similar (such as Knighton and Niton in the Isle of Wight). Local people tend to develop ways of distinguishing similar names, which may not be obvious to outsiders.
Notes: Maybe Ptolemy's Καλατον/Καλαγον should be located here instead of at Burrow-in-Lonsdale.
