Itinerarium Burdigalense

[1] It recounts the writer's journey throughout the Roman Empire to the Holy Land in 333 and 334[2] as he travelled by land through northern Italy and the Danube valley to Constantinople; then through the provinces of Asia and Syria to Jerusalem in the province of Syria-Palaestina; and then back by way of Macedonia, Otranto, Rome, and Milan.

According to the Catholic Encyclopedia, the report is a dry enumeration of the cities through which the writer passed and the places where he stopped or changed horses, with their respective distances.

"[3] The compiler of the itinerary cites the boundaries from one Roman province to the next and distinguishes between each change of horses (mutatio) and stopover place (mansio).

Two give only the Judean portion of the trip, which is fullest in topographical glosses on the sites, in a range of landscape detail missing from the other sections, and Christian legend.
