La Colonnette Mafféienne

Which is to say CIL VI 3492 = ILS 2288, the list of legions inscribed on a column (or two: one is long lost) from the forum at Rome in the reign of Marcus Aurelius.

I don't think I've ever seen it named in this (or any) way in the literature except here:

Les légions romaines sur le Forum : recherches sur la Colonnette Mafféienne

Discovered in the 16th century, it appears to have originally been in the collection of Cardinal Maffei before its transfer to the Vatican Museum (sadly, much of the inscription gallery was closed when I visited; in fact I'm not sure some parts ever form part of the standard itinerary). Photographs are hard to come by - copyright issues prevent it from appearing in the online version of the above article - but I did manage to find one [here].

 This is a partial reconstruction (quite apart from the rest of the image treatment) - parts of the surface of the original have been damaged and the reading of other parts (painted in at some [long] past date) leaves something to be desired. This represents the generally agreed text.
