In the midst of this universal peace, a new and unexpected disturbance arose in Tuscany. Certain citizens of Volterra had discovered an alum-mine in their district, and being aware of the profit derivable from it, in order to obtain the means of working and securing it, they applied to some Florentines, and allowed them to share in the profits. This, as is frequently the case with new undertakings, at first excited little attention from the people of Volterra; but in time, finding the profits derived from it had become considerable, they fruitlessly endeavored to effect what at first might have been easily accomplished. They began by agitating the question in their councils, declaring it grossly improper that a source of wealth discovered in the public lands should be converted to the emolument of private individuals. They next sent advocates to Florence, and the question was referred to the consideration of certain citizens, who, either through being bribed by the party in possession, or from a sincere conviction, declared the aim of the people of Volterra to be unjust in desiring to deprive their citizens of the fruit of their labor; and decided that the alum-pit was the rightful property of those who had hitherto wrought it; but, at the same time, recommended them to pay an annual sum by way of acknowledgment to the city. This answer instead of abating, served only to increase the animosities and tumult in Volterra, and absorbed entire attention both in the councils and throughout the city; the people demanding the restitution of what they considered their due, and the proprietors insisting upon their right to retain what they had originally acquired, and what had been subsequently been confirmed to them by the decision of the Florentines. In the midst of these disturbances, a respectable citizen, named Il Pecorino, was killed, together with several others, who had embraced the same side, whose houses were also plundered and burned; and the fury of the mob rose to such a height, that they were with difficulty restrained from putting the Florentine rectors to death.
