Abstract
The farthest east on the transcontinental road to China which ancient travellers from the Mediterranean borderlands are known to have attained was reached by a party that made its way as far as the Stone Tower, a station in the region of the Pamirs, not far from the watershed between the Mediterranean and the Yellow Seas. This expedition was organized by a member of an old business family, named and described as The only reference to Maes in ancient literature is in a brief notice by Ptolemy , which he derived from his main source, the geographer Marinus of Tyre. Can we find out anything more about this great entrepreneur?
