In Latin, Ostium means “mouth of the river”. And it is exactly at the mouth of the Tiber, in fact, that the first Roman colony was founded (according to Livy) in the 7th century B.C., to protect Rome from possible attacks and to control the big saltworks, at that time extremely important. Fishing has necessarily always played an important role in this area, where ancient forms of fishing still survive. In this video, Mario Salvatori tells us about his love for almost forgotten techniques, such as fishing with the “iacco” (= cast net) or with the “big scale” (called “bilancione” in Italian), similar to the Chinese fishing net, which is still used at the mouth of the Tiber (Fiumara grande). It is a traditional way to experience the river just a few kilometres from the Ostia Antica Archeological Park.
