CIPPUS WITH INSCRIPTION, AFTER 6 CE. DRUGSTORE MUSEUM COHORS VI PR(ÆTORIA) / MVNIT / PER P(EDES) ∞∞ [---]CLX[---?] "The sixth Prætorian cohort made (this) for 2160 (Roman) feet". Damage to the third line makes other letters illegible. The numeration is not our familiar Roman numerals, but uses what we think of as the infinity symbol, ∞, in place of the more familiar M to indicate 1000. It's used twice here, so 2000. Then comes C, 1000, then the upside-down T which is an alternate for L, 50, and X, 10. Adding this up gives us a significant distance, 2160 feet or 640 metres, which probably refers to roadworks, or, less likely, hydraulic works, both of which fell into the purview of the Prætorians. The crumbly stone of the cippus is tufo lionato, or Monteverde tufo, distinguished by its yellow colour.
For #EpigraphyTuesday we find a damaged C1 CE #cippus from along the #viaPortuensis west of central #Rome that records a probable road repair by the sixth #Prætorian Cohort, but using unfamiliar #Roman numerals cut with elegant precision into the yellow tufo. #AncientBluesky 🏺
