The inscription tells us that Publius Aelius Maximus has built this monument for himself and for Veiania Iotape, his freedmen and freedwomen, and the descendants; also for Lucius Genucius Epaphroditus and Maria Deutera and their descendant,s after a subterranean burial chamber has been given to them and the right to come and go and to walk under the portico has been permitted by Publius Aelius Maximus.

The door of tomb I gives access to tombs I, L, M, N, and O. When we enter tomb I, we find tomb L immediately on our right hand.
The entrance of tomb L was provided with jambs, a threshold and an architrave made of travertine, and was flanked by two small windows, both with a terracotta plate.
According to a marble plate with inscription above the door, tomb L belonged to Calpenius Hermes:
