Quick question for the Historians in the Room

[CountArach]

It's possible (though not likely) that the writing and the carving were done at seperate times. Look at the relative depths of each of them - the carving is much deeper than the writing. As for what the text says, if it is latin, there's nothing in there that I can identify, and given how few people would have been fluent enough in latin to read this sort of stuff, it doesn't seem likely in my eyes. Further, if I am not mistaken Medieval Latin often had spaces between words unlike the Ancient version.

Wow, interesting. Best of luck on finding what it is/means. :D

Not exactly my area of expertise.

Not a clue of what it means but there isn't more letters than the clearly seen, the rest of what could be interpreted as letters are eroded marks in the stone; ATNAS|LY|GLE and I separated it because I have doubts there are an L and Y there...
