The original reading of the inscriptions’s left-hand fragment by Carrara in De’ Scavi di Salona is below on the left and that of Higham’s, from King Arthur: The Making of the Legend, on the right. The final letter in line 7, E, is no longer visible as that portion of the fragment was lost after the original reading was made. It has been questioned whether it was in reality an E.
The errors in the original reading are:
Line 1: Missing R and U as well as inverting O and R in ARTORIUS
Line 2: Missing E in GALLICAE
Line 4: Missing a ligatured T in ITEM
Line 6: Misinterpreting a C for a G
Line 8: Ligaturing the O with the P rather than the R in PROVINCIAE
Line 8: Missing L in LI
So, Carrara never seems to have made the error of adding something that is not there. Moreover, the misinterpretation such as occurred line 6 is unlikely to have occurred with the letter following ARM since not many letters are readily mistaken to be an E. Consequently, the missing word was probably ARMENIOS.
There was a smaller inscription of Castus, shown below.
