The room letters are those referred to on the pompeiiinpictures pages at IX.7.19 and IX.7.18.
This plan is to help you accurately locate the rooms shown in the photographs of this house.
The room letters are based on the excavation plan and room descriptions published by Mau in Bullettino dell’Instituto di Corrispondenza Archeologica (DAIR), 1882, page 138.
Please be aware that the plan may differ from any other plans or records both published and unpublished.
