In: UA Magazine 2 - Livestock in and around cities
The cobblestones of the streets in the old city of Pompeii near Rome are scarred by the wheels of wagons that used to be drawn by horses and/or oxen, for carrying goods or for supplying the military. The covered bridge in Florence is now the home of goldsmiths and jewellers who replaced butchers and fish traders, supposedly because a 'Medici' queen complained of the smell.
