After the Romans left the UK, a lot of their tech stayed around. There were still working hypocaust, the roads were still there, the cultural melding ... But some technologies were lost. How extreme or dramatic this was seems to be a matter of debate. I wonder if there were Saxon age brits who were moon-eyed for Roman technology, who kept trying to do things the way the invaders did it. I wonder if other Saxons rolled their eyes at them.
@134318c2 In southern germany there are old roman stone villas with floor heating and all the nice stuff ...and germanic wooden postholes inside it. without the whole infrastructure (and the slaves!) of the romans the old technologies where no longer feasible or usable.
@134318c2 well the Victorians were definitely moon-eyed over the Romans. And Arthurian mythos is full to overflowing with nostalgia for Roman times. But, I don't know that it was continuous from whenever the Arthurian myths were developed until the Victorians. Also, I don't know how much of Romanophilia in Arthurian myth is due to backporting from Victorians, but at least some of it is from Chaucer, who was long before Victorians.
