| Comments: | This stone has been recognised as granito misio, sometimes called marmor misium, which was quarried at Kozak, near Pergamon, Turkey. Euhedral crystals of hornblende are particularly characteristic. It has also been suggested that this might be from Egypt, a tonalite gneiss which is a hybrid of the varieties from Mons Claudianus and Wadi Umm Huyut. It is however atypical of both and intermediate between the two. |
