Reading edition
The pound of 12 ounces of 20 pence used in codes of South Wales seems to have been the pound used in Gaul in Roman times. 'Juxta Gallos vigesima pars unciæ denarius est et duodecim denarii solidum reddunt . . . duodecim unciæ libram xx. solidos continentem efficiunt. Sed veteres solidum qui nunc aureus dicitur nuncupabunt.' De mensuris excerpta. Gromatici Veteres. Lachmann, i. pp. 373–4.
