The mina Italica of 240 scripula of 24 wheat-grains or 20 Roman ounces.
It seems that the Roman pound of 12 ounces was not the only pound in use in Italy. A still older Roman pound of 10 Roman ounces or 5760 wheat-grains seems to have existed,[13] which was in fact a pound of 240 scripula of 24 wheat-grains. And two of these pounds made what was called the mina Italica of 20 Roman ounces. This mina Italica survived into Merovingian times. It contained 480 Roman scripula, and according to authorities quoted by Hultsch[14] the scripulum was so far a common unit in Gaul as to have earned the name of the denarius Gallicus. The number of Roman wheat-grains in the mina Italica was 11,520. Its weight was 545 grammes.
In the Merovingian formulæ and in the early charters of St. Gall there are constant references to fines of so many libræ of gold and so many pondera of silver, from which the inference may be drawn that the pondus of silver was a different weight from the libra of gold. Whether the older Roman pound or half-mina-Italica was the ‘pondus’ or not, the fact that it consisted of 240 scripula may possibly have made it a precedent for the monetary mode of reckoning of 240 pence to the pound, adopted by the Franks and Anglo-Saxons.
This mina Italica has also a Celtic interest. It is curious to note that whilst so late as the tenth century the Cymric galanas or wergeld was paid in cows, the cow was equated with a monetary reckoning in scores of pence, or unciæ argenti, of which twelve made a pound of 240 pence. At the same time in the Cymric Codes there are mentioned, as we shall find, two kinds of pence: the legal pence, probably those current at the time in England of 32 w.g., and the curt pence or scripula of one third less, viz. 24 w.g. Now, whilst 240 of the former would equal the pound of the nova moneta of Charlemagne, and of later Anglo-Saxon reckoning, 240 of the curt pence or scripula would equal the older Roman pound or half-mina-Italica.
Turning from the Cymric monetary system to that of the early Irish manuscripts and Brehon laws, we shall find that it was based on the Roman scripulum of 24 wheat-grains, and not, like the Anglo-Saxon and Frankish system, on the tremissis. And we shall find that though thus based upon the scripulum and the ounce, when payments were made in gold and silver, the reckoning, instead of making use of the Roman or any other pound, counted rather in scores of ounces; i.e. consciously or unconsciously, in so many of the mina Italica.
The mina Attica of 16 Roman ounces or 2 marks.
So much for the mina Italica and its possible Anglo-Saxon and Celtic connections.
The other mina, the mention of which is important, formed the probable basis of Scandinavian reckoning in marks instead of in pounds.
