Note 737 — Chapter V

Prefect of Egypt in the reign of Augustus. This expedition into Arabia completely failed, through the treachery of the guide, a Roman named Syllæus. A long account of it is given by Strabo in the 16th book. “It would be extremely interesting,” says Professor Schmitz, “to trace this expedition of Ælius Gallus into Arabia, but our knowledge of that country is as yet too scanty to enable us to identify the route as described by Strabo, who derived most of his information about Arabia from his friend Ælius Gallus.”
