[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. [138] _I comentari di Frontino intorno le acque e gli acquedotti_: Opera premiata dalla r. Accademia dei Lincei col premio reale di lire 10,000.

[140] Sponges are most frequently found in the _cistæ_ at Palestrina, which were nothing else but toilet-boxes. I have had the opportunity of examining the contents of twelve of them, lately discovered. These include sponges, combs of various kinds and shapes, hairpins, wooden boxes with movable lids, still full of excellent powders, cosmetics, and ointments, and other articles of the _mundus muliebris_.
