[Footnote 65: Of several statements as to the ducal revenue and expenditure which I have seen, none is distinct or satisfactory. The most detailed is in a MS. in the public library at Siena, K. III., No. 58, p. 240, but the sums have been inextricably blundered by the transcriber. See Appendix VIII.] * * * * * The most remarkable incident in Guidobaldo's reign was an outbreak of the citizens of Urbino, dignified in its municipal history by the name of a rebellion, which acquires a factitious importance as the only symptom of discontent that troubled the peace of the duchy, from the death of Oddantonio in 1443, to the extinction of its independence in 1631. We shall condense its incidents from the contemporary narrative of Gian-Francesco Cartolari, who designated himself agent of the Duke, and who, notwithstanding his official position, writes with apparent frankness and impartiality.[66] [Footnote 66: Vat. Ottob. MSS. No. 3142, f. 165, and Oliveriana MSS. No. 390, p. 63.] In August, 1572, the Duke intimated to the council of Urbino that he had received authority from Gregory XIII. to impose a tax of one quatrino per lb. on butchers' meat, and of two bolognini upon every _staro_ of grain and _soma_ of wine;[67] and in October he made proclamation throughout the duchy of these new imposts. It being rumoured that the envoys of Gubbio had obtained for that community a suspension of the obnoxious duties, discontent began to prevail, and on the 26th December one Zibetto, a cobbler, in an inflammatory harangue, at a public assembly dignified with the name of general council, declared that these were exactions under which the poor could not exist.[*68] On his proposal, forty delegates were chosen from the nobility, and sworn to represent the matter to the Duke in person. They repaired to Pesaro, and, on the 29th, had an audience to present the memorial agreed to by the council, which Guidobaldo received, and desired them to go home, promising that an answer would be transmitted when he had considered their statement. They, however, stayed a week, vainly looking for his reply, during which the council met daily at Urbino, and at length they were recalled by an express from the Gonfaloniere. Meanwhile a vice-duke had been sent thither, who, on the 1st of January, 1573, published a suspension of the new imposts throughout the whole state. This concession, however, did not satisfy the discontented, who, in another general council, accredited two envoys to Prince Francesco Maria, begging his intervention to procure an answer to their memorial. Having failed in this object, and finding that troops were being secretly organised to garrison their city, the people of Urbino rushed to arms, closed the gates, and, having mustered above a thousand men, began to strengthen the defences and lay in stores. The Vice-Duke being thereupon recalled, the general council assembled daily in such numbers, that
