Itinerarium; a journal, or an account of the distances of places. The most remarkable is that which goes under the names of Antoninus and Ethicus; or, as Barthius found in his copy, Antoninus Ethicus; a Christian writer, posterior to the times of Constantine. Another, called Hierosolymitanum, from Bordeaux to Jerusalem, and from Heraclea through Aulon and Rome to Milan, under Constantine.—Itinerarium denotes a day's march.
