On this date in 1618, Venice crushed a Spanish conspiracy with sudden violence.
The reality of this conspiracy has been argued for the four hundred years since it was exposed or “exposed” but there is no questioning the security panic experienced by Venice at this moment.
Spain’s viceroy to Naples, the Duke of Ossuna, was massing a fleet that the Serene Republic suspected was meant for her; meanwhile, contradictory rumors of possible conspiracies within the city dogged the Doge.
At last, a Frenchman named Juven informed on confederates and countrymen whom he claimed had taken him into their confidence with the intent to destroy Ven
The Government now determined to act. On the 12th May 1618 [Nicole] Regnault and the brothers Bouleaux were arrested, just when the former had been writing to his sister in Paris, to say that he had a piece of business in hand which would save him the trouble of earning his livelihood for the future, which was true enough. The two Bouleaux, it appeared at their examination, had been engaged at the Spanish embassy in the manufacture of petards and fireworks in connection with a general plan of incendiarism; and they were forced into the admission that the embassy was a perfect storehouse of arms and ammunition, and that the order of the arrangements had been drawn up by Regnault and Pierre … On the person of Charles Bouleaux were found several damning papers; two letters of Lorenzo Nolot, a Burgundian (Pierre’s messenger to Ossuna), directed to a Signor Pireu, and in his stocking two others written to the Duke of Ossuna … The capture of Regnault and the others produced a scare, and there was a sudden exodus from the city, unhindered by the Executive, and emptying the lodging-houses of their motley and disreputable occupants. All who fell into the hands of the Government confessed that everything on their side was ready, and that if Ossuna had been able to support them, Venice must have been overpowered … On the same day which witnessed the arrests of Regnault and the two Brouleaux, orders were transmitted to the proveditor-general at sea to dispatch [naval officers already detained under suspicion -ed.] Pierre, Langlad, and their secretary Rossetti, in such a manner as he might judge fit; in reporting their executions, Veniero stated that the fireworks fabricated by Langlad for the use of the fleet had been in reality destined to burn it. On the 18th Regnault and his confederates were strangled in prison, and their bodies afterward suspended head downward between the Columns. Other summary measures followed, and about 300 persons paid with their lives for their participation in the foolish and flagitious project; but no particulars have been preserved of the exact number or of the mode of disposing them … What sad shocks must have befallen households where a father, or a son, or a brother, whose guilt was unsuspected perhaps by the rest, was seized by the sbirro to be seen no more! What a spectacle the lower Dungeons must have offered during days and days!
