The Fauces of Senex Caecilius

The narrow passageway leading from the door to the atrium is called the faucēs (throat) or vestibulum. Often a dog or a doorkeeper would be stationed here to guard the entryway.

You are able to see all the way through the atrium and tablinum to the peristyle surrounding the garden and the household shrine called a lararium which is located there.

The andrōn is the corridor that leads from the atrium to the peristȳlium.

This resource depicts a typical floor plan for an atrium-style house and descriptions of the various rooms that comprise it.

Sometimes the floor of the fauces would be decorated with a mosaic like this one from the House of the Tragic Poet in Pompeii. Cave canem!
