be in evidence. The epitaphs of Epicureans often expressed some form of the sentiment non fui, fui, non sum, non desidero, "I did not exist, I have existed, I do not exist, I feel no desire," or non fui, non sum, non curo, "I did not exist, I do not exist, I'm not concerned about it." Among the non-elite, fond epitaphs for the young, both freeborn and slaves - Dasen gives examples ranging from 2 years old to 13 - tend to make much of their brief lifetimes, tragically wasted talents, the pleasure they gave and what they would have achieved in life had fate not intervened. For those families who could not afford a durable inscription, the passage of time would have brought considerable anxiety, as such grave markers as they could provide gradually eroded, shifted or were displaced, with the grave's exact location, and the identity of the deceased, lost as the cemetery gradually filled. Many would have received no marker or epitaph at all; most of Rome's slaves were servi rustici, used for agricultural labour, and very few of them had the opportunities afforded to many urban household slaves, to buy their freedom with money earned and a promise of future favours. Almost all would have been enslaved for the whole of their lives, "and it is thought that they practically never appear in the epigraphic (or any other) record." Funerary art Imagines ("images") The "images" ( , ) displayed by some noble Roman families at funerals were usually kept in cabinets made for the purpose, in the atrium of their family home. There is some uncertainty about whether these imagines maiorum ("images of the great ones") were funeral masks, lifemasks, busts, or all of these. The "images" could be arranged in a family tree, with a title () summarizing the individual's offices held () and accomplishments (), a practice that might be facilitated by hanging masks. In any case, portrait busts of family members in stone or bronze were displayed in the home as well. These imagines were most likely made of wax, coloured and detailed to create as accurate a depiction as possible. They were not only used at funerals but were also displayed at important family gatherings such as weddings. They were therefore not housed in the tomb, but in the family domus. Their making was acknowledged as requiring a high level of skill;
