Robert Kaster & spouse did this, and much, much more, and the resulting book – thanks tender sender! – is thoroughly recommended. (And don’t worry: seasoned jaywalkers won’t find the first bit anything like as frightening as they did: they’re drivers rather than walkers, and I’ll bet a really pedantic researcher could dig out something about the dangers of cart traffic in second century Rome.) Recently I also enjoyed the adventures in the Callixtine catacombs (From the oak to the olive, 1868) of Julia Ward Howe – progressive at home, tomb-raider abroad – and Skateboarding on the Appian Way has got to be good.
