Abstract A fragmentary marble inscription preserved in Milan is dedicated to senator Sextus Teidius Valerius Catullus, consul in 31 a.C., who until now has been to us no more than a name carved on the Fasti consulares. This new inscription informs us on the fi rst steps of Teidius’ political career, from the questorship to a not well-defi ned cura. Unfortunately there are no evidences that the slab was found in Milan, but a link to the city could be offered by Terentia Hispulla, Teidius’ presumed wife, member of the Milanese family of the Terentii Hispones.
