Medal Great

Who have already visited guggenheim museum? In the entrance, on the floor there is a great medal?

Has a word written there which seems to be Greek: “APIΣTOФANHΣ”. Who knows their translation?
Thank you very much!!!

Maybe …

“Let each man exercise the art he knows”…
(Aristophanes)

(or)

“Archeseum” (based on an idea of Solomon G. …)

Good luck !
