For here the height on which the acropolis stood is sheer and unlikely to be assaulted; this was the only place where Meles the former king of Sardis [28.0167,38.475] (Perseus) Sardis had not carried the lion which his concubine had borne him, the Telmessians having declared that if this lion were carried around the walls, Sardis [28.0167,38.475] (Perseus) Sardis could never be taken. Meles then carried the lion around the rest of the wall of the acropolis where it could be assaulted, but neglected this place, because the height was sheer and defied attack. It is on the side of the city which faces towards Tmolus.
