Here's a bit of interesting information I came across on a site called Delancy.
tidbits on the city of Florence at the flowering of the Renaissance, the 1400s, the time of Cosimo de'Medici, Filippo Brunelleschi, Donatello, Leonardo da Vinci and countless other guiding lights - tidbits on homosexuals, prostitutes, witches and public spectacle:
"[After the Florentines' military defeat at Lucca] a familiar scapegoat was used to explain the Florentines' ineptness in battle: homosexuality. For years, clergymen such as the Franciscan firebrand Bernardino of Siena had been raging from the pulpit that the crime of sodomy was destroying the city. So famous was Florence for homosexual activity that during the fourteenth century the German slang for 'sodomite' was Florenzer. In 1432, the government took steps to curtail this perceived root of its troubles on the battlefield by establishing an agency to identify and prosecute homosexuals, the Ufficiali di Notte, 'Office of the Night' (a name made even more colorful by the fact that notte was slang for 'bugger'). A less official method of detecting homosexuals was for mothers to rattle their sons' coin bags: if the coins exclaimed, 'fire, fire, fire,' the money was said to be the gift of a sodomite.
"This vice squad worked in tandem with the Orwellian-sounding Ufficiali dell'Onesta, 'Office of Decency,' which was charged with licensing and administering the municipal brothels that had been created in the area around the Mercato Vecchio. The specific aim of these public brothels was to wean Florentine men from the 'greater evil' of sodomy. Prostitutes became a common sight in Florence, not least because the law required them to wear distinctive garb: gloves, high-heeled shoes, and a bell on the head. ...
"Held ... in Florences communal prison, the Stinche ... were more serious Criminals - heretics, sorcerers, witches, and murderers - for whom unpleasant fates awaited: decapitation, amputation, or burning at the stake. Executions took place outside the walls, in the Prato della Giustizia, 'Field of Justice.' These were popular public spectacles - so popular, in fact, that criminals often had to be imported from other cities to satisfy the public's demand for macabre drama."
