I'm assuming that the Artorius in question is Lucius Artorius Castus [0], who was prefect (third-in-command) of the Legio VI Victrix, based in York for most of the second and some of the third centuries. He was first proposed as a prototype for Arthur in the 1920s, and more recently was the basis for the character in Antoine Fuqua's King Arthur (the one starring Clive Owen), though that shifted him forward a few centuries. I'm not sure where this is coming from: > who led resistance to a powerful Scottish invasion around 180 AD First, Castus's dates are unclear: best guess seems to be late 2nd or early 3rd century, but no more precise than that. Second, a "Scottish" invasion? I'm guessing this is journalese for "Pictish", but I suppose there could have been an incursion by Scotti (from Ireland, at that time) that got as far inland as York. My Googling skills aren't good enough to find the relevant reference in Dio. [0] https://en.wikipedia.org/wiki/Lucius_Artorius_Castus https://en.wikipedia.org/wiki/Lucius_Artorius_Castus
