Antonine Itinerary

The Antonine Itinerary (,  "The Itinerary of the Emperor Antoninus") is a famous itinerarium, a register of the stations and distances along various roads. Seemingly based on official documents, possibly from a survey carried out under Augustus, it describes the roads of the Roman Empire. Owing to the scarcity of other extant records of this type, it is a valuable historical record. Almost nothing is known of its date or author. Scholars consider it likely that the original edition was prepared at the beginning of the 3rd century: although it is traditionally ascribed to the patronage of the 2nd-century Antoninus Pius, the oldest extant copy has been assigned to the time of Diocletian and the most likely imperial patron—if the work had one—would have been Caracalla.
