“[This] has been set up
For mother Tettedia Calliope and[her] sister Tertulla. Niche I.”
This columbarium slab marked the burial niche of two women, Tettedia Calliope and her sister Tertulla. Presumably it was set up by Tettedia’s children since she is addressed as mother. The last two words indicate the number of the burial niche.
