Thank you Rhiannon, I am already feeling homesick, especially for that walk along the little valley of Nettleton Shrub. Problem with Bath it is such an R.... place. Anyway I note the writer mentions that Iron Age people had a thing about dogs, just like me in fact and the 'healing dogs' of the temples surely must have been commandeered from the native people by the romans.
My slightly untidy blog on Nettleton Shrub below, a place I fell in love with ;)
