A network of post-horses and couriers knit together the entire peninsula and connected Italian merchants to northern Europe.

Omodeo, the founder, began with a courier service for the Venetian republic, operating a chain of postal stations between Venice and Milan and between Venice and Rome. In 1460, the Tasso family took exclusive charge of postal serice for the Papal States, a monopoly it held until 1539.\"§REF§Ingrid Rowland. Noah Charney. 2017.
