[137] When Maxentius repaired the Appian Way in 309, one of these
commemorative columns was converted into a milestone, the seventh from
the Porta Capena. The column was removed in the Middle Ages to the
Church of S. Eusebio on the Esquiline, where it was seen and
purchased, at the beginning of the last century, by cardinal
Alessandro Albani. It now belongs to the Capitoline Museum.
