The postal guides were published by printers to offer travelers, but not only, a useful tool to organize the trip, not differently as it happens today with tourist guides. This genre began in the mid-16th century: the first practical guide for travelers was published in 1552 by Charles Estienne in Paris. The postal guides were widely used and, thanks to their format, could be contained in the pockets of clothes. During the journey they were consulted constantly, for this reason these guides are often found worn and wrinkled today. They contained useful information for the journey such as: the location of the post stations, the routes to reach your destination, useful advice on changing coins, on how to stay healthy, how to take care of the horses and the indication of the materials necessary for a safe and comfortable journey. The first printed itinerant guide is that of the French publisher Charles Estienne in 1552. In Italy the guide of Ottavio Codogno, lieutenant of the Milan Post Office in the second half of the seventeenth century, had great success, so much so that it was published several times during the seventeenth century .
