Here is one of the earliest known reliefs to commemorate the legitimate marriages of former Roman slaves.
The Funerary Stele of Aurelius Hermia and his wife Aurelia Philematium is from the tomb on Via Nomentana, and dates to ca. 80 BCE.
The British Museum provides the following prose translation of the funerary stele:
"Aurelius Hermia, freedman of Lucius, butcher by trade from the Viminal Hill. My partner who departed this life before me was pure of body and loving of spirit. She was the only one for me, and lived her life faithful to her faithful husband, with equal devotion. She never failed in her duties through self-interest or greed. Aurelia, freedwoman of Lucius.
Aurelia Philematio, freedwoman of Lucius. In life, I was given the name Aurelia Philematium (little Kiss) and led a chaste, modest and sheltered life, faithful to my husband. Aurelius, my husband, whom I now sadly miss, was a fellow freedman. He was, in fact, much more to me than even a parent. He took me into his care at the age of seven. Now at the age of forty, I fall into the hands of death. He flourished in the eyes of others due to my constant and close support.”
