__Vallata mari Scironia rupes,
Et duo continuo connectens aequora muro Isthmos .
Claudian de Bell. Getico, 188.
The Scironian rocks are described by Pausanias (l. i. c. 44, p. 107, edit. Kuhn) and our modern travellers Wheeler (p. 436) and Chandler (p. 298). Hadrian made the road passable for two carriages [Pausan. i. c. 44, 6, ed. Bekker].
