"A wide survey over four millennia is possible for quarrying tools and techniques because of their simplicity and long-lived traditions. The chief contribution of the Romans was their organisation of the stone trade by mass production, standardisation and long-distance transport. Indeed, in post-Roman Europe, especially in Britain, it was the excellence of Roman building stone which allowed so much subsequent 'quarrying' in the buildings themselves. One exception in Saxon times was the quarry for Bradford-on-Avon's church. With the 12th-century spurt in church building activity, however, natural stone quarries once more became common and distribution methods familiar to the Roman world re-emerged." - COPAC.
