Lobus Caecilius

Lobus Caecilius was a man who lived in Pompeii before Vesuvius erupted on 24 August 79. Husband of Metella and father to Evelina and Quintus, Caecilius was a marble trader with political ambitions; it was to impress the augur Lucius Petrus Dextrus, that he bought the Tenth Doctor's TARDIS at the market, intending to display it as "modern art".

Along with his family, Caecilius was spared from the devastation of Pompeii by the timely intervention of the Doctor. By early 80, Caecilius and his family had resettled in Rome, and adopted the Tenth Doctor and Donna as their household gods.

The Twelfth Doctor remembered Caecilius when seeing himself in a mirror for the first time, having seen his face somewhere before.
