constructing and mounting a porpax

[Giannis K. Hoplite]

Sure,there certainly were painted interiors,as you said,some of them very elaborate. At least one or two boeotian grave stelae show griffins and such desighns painted on the interior. But I don't remember geometric designs and since such cercular bronze re-enforcements have been found,evidence points to that way. Which-I repeat- doesn't mean anything about the authenticity of yours,and in facts it adds to the overall impression.
As far as I know,the rings have never been mentioned in greek literature thus they don't have any specific name other than,"rings" or "fittings". So,you won't tie any rope on them?
