I was told today that when foundations were being laid for the new road bridge across the Tamar in Launceston some years ago, the excavations uncovered a set of Roman bridge foundations. (Launceston may, or may not, be the same place that is called Uxelis in Ptolemy's Geography). The internet knows nothing of this intriguing fact(ish)*. My source is the business partner of the coordinating civil engineer on the bridge (now retired).
This sort of thing is the reason that I still haven't got my 'Marcus Goes To Dumnonia' story into any kind of order despite having started it about a year and a half ago. I am almost tempted to ditch it as fiction and issue it as a local history leaflet instead. :-D
*factish is a word I think I have just invented for something that may, or may not, be a fact.
