The oldest document pertaining to the use of masks in Venice dates back to 1268. In the document it is written that it was forbidden for masqueraders to practice the game of the 'eggs'. From the early 14th century onwards new laws started to be promulgated, with the aim of stopping the relentless moral decline of the Venetian people of the day. This restrictive carnival legislation started with a decree in 1339 prohibiting masqueraders from going around the city at night. A decree dtd 1458 helps us understanding how libertine the Venetians of the day were: it forbade men from entering convents dressed as women to commit 'multas inhonestates'! Another decree dtd 1603 too attempted to restore morality in the convents.

Masqueraders were banned from entering the nuns' parlous - it had been the convention to sit in the parlous and talk to the nuns. Frequently, decrees were promulgated, prohibiting masqueraders from carrying arms or any instrument which could cause harm, or other decrees which forbade masqueraders from entering churches. This obligation was extended to the townsfolk who were not allowed to enter churches wearing 'indecent attire'. In 1608 another decree from the council of 10 was issued declaring that wearing masks throughout the year posed a serious threat to the Republic. To avoid the terrible consequences of this immoral behavior, every citizen, nobleman and foreigner alike, was obliged to only wear a mask during the days of carnival and at official banquets.

The penalties inflicted for breaking this law were heavy - for a man this meant two years in jail, 18 months' service to the Republic galley-rowing (with ankles fettered) and a 500 lire fine to the Council of 10. As for women, they were whipped from St Mark's all the way to Rialto, then held to public ridicule between the two columns in St Mark's. They were banned from entering the territory of the Venetian Republic for 4 years and had to pay the 500 lire fine to the Council of 10. 50 years after the decree of 1608, the Council of 10 published a proclamation on the 15th January reaffirming the ban on wearing masks and bearing arms.

It was further prohibited to enter holy places wearing a mask and it was expressly forbidden to wear religious clothes with a mask. In the same decree the use of drums was banned before midday, and even dancing of any description was prohibited outside of the carnival period. As many Venetian nobles used to go gambling wearing a mask to avoid their creditors, in 1703 masks were banned all year round from casinos.

Two different decrees (1699 and 1718) saw the prohibition of wearing a mask during Lent and other religious festivals which took place during carnival. In 1776, an act introduced to protect the by now forgotten 'family honor', forbade all women from going to the theatre without a mask and cloak. After the fall of the Republic, the Austrian government forbade the use of masks for both private parties and elite parties (e.g., la Cavalchina della Fenice). The Italo-American government was more open but now it was the Venetians who were being diffident. Venice was no longer the city of carnival, but just a little imperial province without personal freedom. During the second Austrian government it was once again permitted to wear masks.
