A century later (in Henry VII's time) an Act was passed to prevent butchers killing beasts in walled towns, the preamble to this Act declaring that no noble town in Christendom should contain slaughter-houses lest sickness be thus engendered.

It was Venice which, in the same year, first initiated vigorous State sanitation. Disinfection was first ordained by Gian Visconti, in Milan, in 1399. The first quarantine station of which we hear was established in Venice in 1403.
