After this the licensed Hells carried on their golden commerce in full security, but not entirely without competition, in spite of the aforesaid pains and penalties which were in several cases enforced. A curious and characteristic consequence of such a state of affairs was the use to which certain diplomatic representatives put their mansions, making good, or rather bad, use of the immunity from interference which their office of Envoy conferred. M. le Chevalier Zeno, the Venetian Ambassador, turned his house into a regular casino, admitting any one into it who would play. For those of the lowest degree a particular room was reserved, known to its habitués as "l'enfer." Remonstrances and representations from the authorities were powerless to effect the cessation of what became a public scandal, the Venetian Embassy continuing to be little but a gambling-hell, till the departure of the Ambassador in question. Three other Ministers also maintained establishments of a similar kind. These were the Prussian Envoy, who resided in the Rue de Choiseul, the Envoy of Hesse-Cassel, whose house was in the Rue Poissonnière, and the Ambassador of Sweden, whose gambling establishment was on the Place du Louvre, at a house bearing the inscription "Écuries de M. l'Ambassadeur de Suède." The somewhat singular methods employed by the enterprising Diplomats in question were very freely commented upon in a report issued by the "Lieutenant de Police" in February 1781, nothing, however, being done to check the scandal. On the contrary, certain members of the _noblesse_, being struck with the pecuniary advantages to be reaped from keeping a gaming-house, followed the example of the Ambassadors, M. le Marquis and M. le Comte de Genlis presiding over establishments of this kind in the Place Vendôme and in the Rue Bergère. It became no uncommon thing for Chevaliers de St. Louis to act as bankers or croupiers. Owing to the decoration they wore they were not subject to the same jurisdiction as ordinary mortals, besides which, many of them were excellent swordsmen. This naturally gave them a great advantage in the case of any protest on the part of the players against the methods employed by the bank, a circumstance which eventually led to a royal prohibition of further gaming enterprises being undertaken by Chevaliers of this Order.
