Limestone rectangular block pierced at one end for a tethering rope to be passed through. Used to tether an animal in a stall. Carved into one side of the block is a cartouche containg a name of king Akenaten (Amenhotep IV). Don't match with the two broken inscribed tethering stones listed in the Amarna Small Finds Database (29/334 and 31/473).
From a building units intended for the housing of different kinds of animals such as the North Palace. Similar tethering stones from Amarna are now in other museums: e.g., Brooklyn no. 25.886.18; Penn Museum E648B.
