Hi, Thank you very much for your reply. I have done some research since I posted this question and found something different from what you said. (I am no specialist in geology though). I understand that one of the methods of the surface rock-salt mining used since ancient times in many countries (China , for one) is actual cutting small pieces of rock-salt and boiling them in water afterwards. When salt is mined this way, the hillside gets covered by terraces , or benches on which a few workers can stand, and which make the transporting of the cut rocks easier. What interests me most, however, is whether they did the same thing in late Byzantium (11 c.). Thank you again, Gregory
