But Thrasyllus told his master about Alexander the Great. When Alexander founded Alexandria, the oracle of Ammon was the most celebrated in Egypt; and Callisthenes and Plutarch relate how the great Macedonian started from Parætonium, on the coast, to make his way through the desert by way of the oasis. Violent south-winds attacked his retinue; but he did not give in, though sand-storms nearly swallowed him up, with his elephants and camels. Suddenly, however, kindly showers fell, at the bidding of the gods, and the winds abated and the sand-storms dropped. Two crows flew beside the great Alexander and guided him to the oasis.

At the first ray of dawn, after a refreshing sleep, the journey was resumed, the monotonous journey, the endless journey. It was the last day but one; and, when the halt was called, it appeared that the drivers and guards had cut open the water-bags and drunk their fill of the water. Caleb grew furious and instantly drew his dagger and wanted to fling himself on the Libyans and Arabs; but they also drew their daggers and everybody shouted and screamed and yelled. Then Lucius intervened and quieted them all and gave them money; and they fell on their knees and sobbed and begged his pardon for drinking up the water, but they had been so thirsty and they accused Caleb of being too sparing with the ration. And Caleb defended himself and said that in the desert one had to be sparing and not gulp down all the water at once, without thinking of the morrow, of the animals and of the noble lord, who now had not a drop of water left. But the noble lord caused a heavy basket full of lemons to be let down from his elephant and gave each of the guards and drivers one lemon and told them that they must now hold out, by sucking this lemon, until they reached the oasis. And they kissed his hands and abased themselves before him and caressed his legs and called him Osiris and Serapis and Ammon-Râ and their life’s benefactor.

Men and animals were exhausted, but they allowed themselves hardly any rest that night and no one slept and all wanted to go on, ever on, in the last spurring of their energies.

Was it, after the sleepless night, because of that exhaustion and that last spurring, an atmospheric phenomenon, an hallucination, an illusion, a fata morgana? In the first rosy glimmers of the dawn, reflected from the east to the west, there rose in the west as it were a dream, a nebulous dream-vision of unsubstantial forms, the vague paradisial vision of barely-outlined, rose-tinted trees, slender, shadowy trunks and palm-crowns suffused in rosy light; and then the straight lines, no more than an azure shadow, of walls, of roofs, terraces, domes.

Was it a vision, was it a dream? No, it was real; and Caleb jubilantly pointed and shouted:

“Ammon-Râ! Ammon-Râ!”

“Ammon-Râ! Ammon-Râ!” repeated the guards and drivers, yelling wildly and cheering like madmen, for the oasis took colour, the trees became more clearly marked and the temple, large as a town, now stretched its walls impressively.

The horses sniffed the air and neighed, the elephants waved their trunks, the camels swung out their legs, the men thrust forward their throats and inhaled the fragrance of verdure and the coolness of running wells; and the inhabitants of the oasis, poor natives in the service of the priests of the temple, poured out of their huts to meet the caravan and knelt in the road, offering split coconuts, juicy oranges and scarlet fruits, of strange shapes and juicy pulp, and earthenware dishes full of water limpid as flowing crystal.
