“To the good and innocent (?) Benedictus who lived four years and 20 days.”
This Christian inscription probably marked the tomb of a four-year-old. His name was Benedictus and he died when he was four years and twenty days old. The rest of the text is difficult to decipher since there are several syntactical and grammatical mistakes. For example, the word vixit (he lived) is spelled bixit, and the abbreviation AN for annis (years) is reversed. The first line presumably has to be translated as “To the good and innocent,” but the word ‘innocent’ is in the plural instead of the singular like the word ‘good.’
In the center of the inscription a prominent Chi Rho has been engraved. This combination of the Greek letters chi and rho is a common christogram, using the first two letters of the word Christos.
