One of the secretaries to the council of ten was an expert in the breaking of codes and secret ciphers. Every foreign embassy or foreign household in the city had one or more resident spies. The foundations for foreign merchants, like the Fondaco dei Tedeschi for the merchants of Germany, were packed to bursting with spies; the Venetian weighers and brokers on those premises were known to work for the government in a semi-official capacity. One great lady of Venice, Elisabetta Zeno, held a salon for certain important senators; behind a screen were hidden two clerks, who for her later benefit noted down everything that was said. When the Venetians became informed of the conspiracy, they suspended the senators from any public office. Elisabetta Zeno herself was exiled for life to Capodistria.

The Venetian merchants who travelled to other lands or other cities were especially useful; it is apposite, too, that in a mercantile state, the language of merchants was used as a code. The Turks, for example, might be described as “drugs” and the artillery as “mirrors” in a fictionalised commodity market.

Indeed the habit of denunciation might be seen as a thwarted or twisted expression of civic pride and civic belonging. It is embodied in the
