The Oracle Will See You Now.
In 331 B.C., Alexander III of Macedonia journeyed from a new city on the Mediterranean coast of Egypt, a city that would soon give rise to one of the seven ancient wonders of the world, and which three-hundred years later would provide the last gasp refuge for Mark Antony and Cleopatra against the onslaught of the first Roman emperor, Augustus.
Modestly dubbed Alexandria by the conqueror of the known world, he walked through roughly 300 miles of barren desert from the city to the Siwa oasis, home of the Oracle of Amun, who promptly (one can only assume it was prompt, what with the conquerer of the known world showing up on your doorstep in the middle of the Sahara desert) informed Alexander he was the son of Zeus, a child of the Gods, helping to solidify his rule in Egypt.
