This verse is translated:- "Now that same day two of them were going to a village called Emmaus, about 7 miles from Jerusalem."
Shortly before he died in December 2004, Carsten Thiede discovered what he believed to be the ruins of Emmaus just 46 stadia from the Old City of Jerusalem in the West Jerusalem suburb of Moza. The trouble was that this appeared to contradict the 60 stadia ('about 7 miles') of Luke.
If, however, we take our cue from Eratosthenes, Pliny and more recently Sir Fred Hoyle, there is reason to think that an 'itinerant stadium' may be 157 metres in length, rather than the standard 185 metres usually quoted. This would reduce the distance from Jerusalem from 7 to under 6 miles and make sense of Luke's geographical reference.
