Thus marble slab, dating to the 3rd century AD, was found in 1939 in Rome, in the area between via della Consolazione and via del mare below the Capitoline hill.
It's a dedication to the Goddess Caelestis for a safe journey going (itus) and returning (reditus). Caelestis temple was located on the Capitoline hill.
The inscription says: " to triumphal Caelestis, Jovinus donates this in fulfillment of a vow."
There is a dove represented in the centre of the panel and a relief bearing four footprints on the side of the inscription.
