The inscription, in debased
Roman capitals, reads "Rialobrani Cunovali fili", which translates as "Rialobranus son of Cunovalus." Rialobran is not known elsewhere, but he may have been a
Cornish petty king or tribal leader.
Rialobran (or
Ryalvran) may be
Cornish for "royal raven", whereas
Cunovallos may be
British for "famous leader" (being
cognate to the second element in the surname
McConnell), thus the inscription would read "royal raven son of famous leader". Alternatively,
Cunovalus may be Cornish for "worthy hound". Antiquarians, at one time, used to identify Cunovalus with the pre-Roman British king
Cunobeline. ==Dating==
