Each side of the cubiculum, except that of the entrance, usually contains a recessed tomb, either a table-tomb or an arcosolium.
The cubiculum was originally designed for the reception of a very limited number of dead.
Another motive for multiplying the number of graves operated when the cubiculum contained the remains of any noted saint or martyr.
Each cubiculum was usually the burying-place of some one family, all the members of which were interred in it, just as in the chantry-chapels connected with medieval churches.

Explorations conducted in the cemetery of Domitilla in 1897-1898 brought to light a fine double crypt with frescoes representing Christ seated between six male and female saints; also an inscription relating to a new saint (Eulalius) in a cubiculum of the 3rd century.
We see a real man, but a man helpless anywhere save in the study or in the convent - a little fresh-coloured man, with soft brown eyes, who had a habit of stealing away to his cubiculum whenever the conversation became too lively; somewhat bent, for it is on record that he stood upright when the psalms were chanted, and even rose on his tiptoes with his face turned upwards; genial, if shy, and occasionally given to punning, as when he said that he preferred Psalmi to Salmones; a man who perhaps led the most placid uneventful life of all men who ever wrote a book or scribbled letters.
In a cubiculum leading out of a gallery in the vicinity there was also discovered an interesting impression in plaster of an inscription of the mother of Pope Damasus, beginning: HIC [[Damasi Mater Posvit Lavren[Tia Membra]]].
