Catstane, an ancient monumental stone in the Edinburgh section of Kirkliston parish, on the peninsula between the Almond and Gogar Burn, 3½ miles WNW of Corstorphine village. Some believe it to commemorate the slaughter, near the spot, of Constantin, King of Alban, in a pitched battle, in the year 997, with Kenneth, son of Malcolm, which St Berchan, however, clearly places on the Tay; the late Sir James Simpson, on the other hand, in a monograph reprinted among his posthumous Archœological Essays (1872), asks, ' Is it not the Tombstone of the Grandfather of Hengist and Horsa?' Perhaps it is.
