Another early visitor to the oasis was Lysander the Spartan. Being disappointed by the oracle of Dodona he travelled to Siwa, under colour of making a vow at the temple, but hoping to bribe the priests to his interests. Notwithstanding “the fullness of his purse” and the great friendship between his father and Lybis, King of the Ammonians, he was totally unsuccessful, and the priests sent ambassadors to Sparta accusing Lysander of attempting to bribe the holy oracle. But “he so subtly managed his defence that he got off clear.” The Greeks held the oracle of Ammon in great veneration. The Athenians kept a special galley in which they conveyed questions across the sea to Libya. Mersa Matruh, sometimes called Ammonia, was the port for Siwa, and it was here that the ambassadors and visitors disembarked and started on their desert journey to the oasis. The poet Pindar dedicated an ode to Jupiter Ammon, which was preserved under the altar of the temple for some six hundred years; and the sculptor Calamis set up a statue to the god of the Ammonians in the Temple of Thebes at Karnak. In 525 B.C., Cambyses, wishing to consolidate his newly acquired dominions in Northern Africa, dispatched two expeditions, one against Carthage, the other into Ethiopia. He made Memphis his base of operations and sent 50,000 men as an advance party to occupy the oasis of Ammon. His generals had orders to rob and burn the temple, make captives of the people and to prepare halting-places for the bulk of the army. They passed the oasis of Khargeh and proceeded north-west. But the whole army was lost in the sea of desert that lies between Siwa and Khargeh. The Ammonians, on inquiries being made, reported that the army was overwhelmed by a violent sand-storm during a midday halt. But it is more probable that they lost their way during one of the periodical sand-storms which are so prevalent in this desert region, and were overcome by thirst in the waterless, trackless desert. There was no further news; they never reached the temple, and not one of the soldiers returned to Egypt. This huge army still lies buried somewhere in that torrid waste, and perhaps some fortunate traveller may at a future date stumble unawares on the remains of the once mighty host. In the old Arabic history there are two other stories of armies that were lost in the desert. In one case it was a Siwan army which opposed the Mohammedan invaders, and in the other case an army of raiders from Tebu were lost on their way to attack the oasis. In 500 B.C., Siwa and the other oases were subjected to Persia, and in the following year Cimon, the celebrated Athenian general, sent a secret embassy to the oracle while he was besieging Citium in Cyprus. The deputation was greeted by the oracle with the words, “Cimon is already with me,” and on their return it was found that Cimon had himself perished in battle. The foretelling of Cimon’s death augmented considerably the reputation of the oracle.
