Stallholder (The Fires of Pompeii)

The stallholder was a male human who lived in Pompeii in the year 79. He owned a stall, where the Tenth Doctor parked the TARDIS. 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 TARDIS as a piece of "modern art" to Lobus Caecilius for 15 sesterce. Confronted by the Doctor, he told him how to find Lucius. (TV: The Fires of Pompeii)
