Strabo, Geography

After Daphnus one comes to Cnemides, a natural stronghold, about twenty stadia by sea; and opposite it, in Euboea, lies Cenaeum, a cape facing the west and the Maliac Gulf, and separated from it by a strait about twenty stadia in width. At this point we have now reached the territory of the Epicnemidian Locrians. Here, too, lying off the coast, are the three Lichades Islands, as they are called, named after Lichas; and there are also other islands along the coast, but I am purposely omitting them. After twenty stadia from Cnemides one comes to a harbor, above which, at an equal distance in the interior, lies Thronium. Then one comes to the Boagrius River, which flows past Thronium and empties into the sea. They also call it Manes. It is a winter stream, so that at times one can cross it dry-shod, though at other times it has a breadth of two plethra. After this one comes to Scarpheia, which is situated ten stadia above the sea, thirty stadia distant from Thronium, and slightly less from the harbor itself. Then one comes to Nicaea and Thermopylae.
