This cylindrical epigraphic monument dedicated to Imperator Caesar Marcus Aurelius Probus Pius, Felix Invictus, indirectly exalting this emperor between July 276 AD and September 282 AD, is what remains of a

milestone. These types of

milestones served to mark, along the

viae (roads), the distance from the political-administrative forum of the civitas capital (of each civic community) to the border limits of the territory. This

milestone, identified outside its original context and used as construction material, lacks large part of the lower section, hindering the identification of the remaining titles associated with the emperor and the number of miles the monument marked from the centre of

Felicitas Iulia Olisipo.
