Madam,
My name is Adam Roberts, and I am a professor of lingusitcs at Oxford Universtiy. I was recently directed to your request for assistance in translating a document by a collegue of mine. I believe I have seen something like it once before in my studies, and would happy to help as much as possible. It may take some time as I will have to search through my old notes.
I wonder if you could send me any other samples of that language to refrence in the meantime, and would be curious where you came by such a curious tomb.
Regards,
Dr. A. Roberts.
