Stallholder (The Fires of Pompeii)

A stallholder owned a stall in Pompeii in the year 79. Donna Noble, wondering how the TARDIS telepathy field would translate Latin to a Roman, went up to him and said "Veni, vidi, vici", to which he replied, "I no speak Celtic". He later sold the Doctor's TARDIS, which was parked near his stall, as a piece of "modern art" to Lobus Caecilius for 15 sesterce. Confronted by the Doctor, he told him how to find Caecilius.
