Cosmas Indicopleustes was a Greek man who claimed the earth was flat and lay between the heavens (consisting of a rectangular vaulted arch). His work was widely rejected by Greeks who staked claim in Pythagoras original theory that the earth was a sphere. The Cosmas is a wide organic rectangular vaulted ring that is handcrafted in fine silver then antiqued for a vintage finish. Wear it everyday, it will make your world go round!
