They were taken over by most of the world (from Babylon as far as we can tell) and standardized in various ways in different cultures. But when better means came along, (candles, clepsydra, pendula, mainsprings, etc.) they were measured off in 12s again, despite rampant decimalism in most places and worse in some: 7 or 9, say). |
