The rigorous portal made of tuff and the construction technique of the internal walls indicate that the house was originally built in the 2nd century BC but underwent major restructuring and fine redecoration of all sections in the last period of life of the city, when the Caecilii family became the new owners. The bronze portrait found in front of the tablinum, currently exhibited at the National Archaeological Museum of Naples, is dedicated to the founder and owner of the house in 79 AD, Lucius Caecilius Iucundus.

Cecilio Giocondo was a banker, as evidenced by the exceptional discovery in the house of his archive of 154 waxed boards which recorded the amounts paid between 52 and 62 AD to persons on whose behalf he had sold goods (especially slaves) or received rents, while retaining commission at 1-4%. Two marble reliefs were discovered in the house, which adorned the home chapel (lararium) of the atrium and represented the effects that the earthquake of 62 AD had on some public buildings in Pompeii.

Date of excavation: 1844; 1875-1876.
