Hexagonal tile with a green glaze and inscription

Hexagonal tile of quartz-fritware. On a ground of thick green glaze a border parallel to the outline is applied in luster, containing an inscription in Arabic characters: 'In the name of Allah, the Merciful, the Compassionate. Allah is One. He is the God to whom all beings turn with their needs. He has not begotten and is not begotten. He has no equal in anyone.' (Quran chapter 112). In the center stand the names of the Twelve Imams. From the palace of Selim II in Adrianople. The metallic luster has almost completely become dull, so that the inscriptions are only visible under certain lighting. Damaged at the corners.
