Renaissance cities were generally small by our standards, but large enough that it was possible to hide in them after committing a crime – but if the authorities really wanted to find you then eventually they would. After all, too many people knew too many others, strangers were often objects of curiosity and there are only so many places you can buy food or seek shelter. So if you really want to be safe, you get out. Given that Italy was a patchwork of independent city states, only a few miles’ or hours’ flight could get you into the jurisdiction of the neighboring city. Much in the same way that modern states often have trouble finding, let alone extraditing wanted criminals from abroad, this could well mean safety, especially if the two cities were not allies.
Of course, the authorities knew this too, and would often take steps precisely to prevent this. The most advanced response was, needless to say, in Florence. There, when a serious crime was discovered, three cannon shots were fired as an alarm. At once, the city gates were closed to anyone without a special permit to leave, river traffic along the Arno was halted and barges were inspected before they could pass on, while the officials of neighbouring villages would ring the church bells to warn local farmers to assemble to help search for fugitives.
Although it was not impossible to lie low inside the city, this was a remarkably organised system for its time. Just think how this might be in the 1510 setting, with hot-air balloons and gliders lofted to scan the surrounding territory and clockwork carriages clicking and clattering along the roads in pursuit. Of course, a criminal who has also prepared himself could well seek to flee by air, or perhaps using a clockwork bicycle of his own…
