The ruins of an ancient city have been discovered at Teffah
in Lower Nubia, which are supposed to correspond with the ancient Taphis.
It was in the neighbourhood of large stone-quarries. On the opposite side of the river was a suburb called Contra-Taphis. Both towns in the 5th century A.D. were occupied by the Blemmyes.
