The Passio Typasii survives in only one manuscript and was published for the first time in 1890. It purports to describe the trial and death of a Mauretanian martyr, a military veteran by the name of Typasius, during the Diocletianic persecution. However as recently demonstrated its literary borrowings, from the Breviarium of Eutropius and the Vita Martini of Sulpicius Severus, suggest that it is a mere fiction and that it should be dated after c. A.d. 396. It is the purpose of this note to draw attention to its preservation of an otherwise unattested title, that of the praepositus saltus, and to expand upon the significance of this title for the interpretation of the work. This title only occurs fully in one passage, being elsewhere abbreviated to praepositus, and this passage is of some interest therefore.
