Comments
See A. H. SAYCE - The new neo-Phrygian inscriptions

'That akaralasun must signify 'a stair-way' is shown by the position of the inscription in a panel facing the summit of a great flight of steps cut in the rock.'

V.P Neroznak - Reconstructing Languages and Cultures p. 277, translates it as sarcophagus.
