"Timbuktu was once a center of learning that boasted a library in ancient times rivaled only by those existing in Alexandria and Rome. Political upheaval contributed to the city's downfall, but the changing climate provided its death knell. The approaching sands threatened to bury what remained of this once great civilization." In the underground basement of this former great library, on a hot windy day in June, Professor William Weston discovered the map; his goal at last accomplished after years of tedious work. No longer would he have to suffer eyestrain, looking through dusty materials in obscure places and following trails that frequently led to dead ends." Enoch "was now within his grasp." "Rachael Goldstein's knowledge of ancient languages allowed her to interpret the document for the Professor under the light of a candle held by the old custodian. When she finished translating, this old man took a fistful of American dollars and turned his back as they departed with the document. With the ancient map in hand, the pair traveled to their tents on the outskirts of Timbuktu where Imnah, their servant, waited with tubs of hot water to remove the day's accumulated dirt and sweat."
