From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
Intermarriages between persons belonging to different confederacies were to be invalid, and no one might be a freeholder in more than one of them. All royal officials, as well as their grown-up sons, were obliged to leave the country and resort to Italy on pain of death; the Romans still dreaded, and with reason, the throbbings of the ancient loyalty.
The law of the land and the former constitution otherwise remained in force; the magistrates were of course nominated by election in each community, and the power in the communities as well as in the confederacies was placed in the hands of the upper class. The royal domains and royalties were not granted to the confederacies, and these were specially prohibited from working the gold and silvei mines, a chief source of the national wealth; but in 596 they were again permitted to work at least the silver-mines.(6)
6. The statement of Cassiodorus, that the Macedonian mines were reopened in 596, receives its more exact interpretation by means of the coins. No gold coins of the four Macedonias are extant; either therefore the gold-mines remained closed, or the gold extracted was converted into bars. On the other hand there certainly exist silver coins of Macedonia -prima- (Amphipolis) in which district the silver- mines were situated. For the brief period, during which they must have been struck (596-608), the number of them is remarkably great, and proves either that the mines were very energetically worked, or that the old royal money was recoined in large quantity.
