The Antonine Itinerary is one of the most famous Roman "itineraries" where the main communication roads of the Roman Empire were collected in a series of lists of stop points and the distances that separated them. Its name does not seem to be related to Emperor Antonine Pius, but rather to Marcus Aurelius Severus Antoninus Augustus, known as Caracalla, who ruled the Roman Empire from 211 to 217.
The Antonini Itinerarium is most likely based on official documents, probably from a study organized by Julius Caesar and developed during the reign of Augustus. We do not know for sure about the author. It is considered probable that the date of the original edition is at the beginning of the third century, while what has come to us probably corresponds to the times of Diocletian.
The route named Item ab Arelato Narbone, inde Narbone, Tarracone, Carthagine Spartaria, Castulone or Itinerario 2 (Saavedra 1862) is another long route that crossed the Iberian peninsula from the north-eastern Pyrenees to the South, finishing in Castulone, in the upper Baetis (Guadalquivir) river. This route linked 34 mansiones in a very long journey of 732 mp, the longest route of the Antonine Itinerary within the Iberian Peninsula.
