Two tales of a city: The historical race to -discover- one of the world's most mythologized places, and the story of how a contemporary band of archivists and librarians, fighting to save its ancient manuscripts from destruction at the hands of al Qaeda, added another layer to the legend. To Westerners, the name -Timbuktu- long conjured a tantalizing paradise, an African El Dorado where even the slaves wore gold. Beginning in the late eighteenth century, a series of explorers gripped by the fever for -discovery- tried repeatedly to reach the fabled city. But one expedition after another went disastrously awry, succumbing to attack, the climate, and disease. Timbuktu was rich in another way too. A medieval center of learning, it was home to tens of thousands - according to some, hundreds of thousands - of ancient manuscripts, on subjects ranging from religion to poetry, law to history, pharmacology, and astronomy. When al-Qaeda-linked jihadists surged across Mali in 2012, threatening the existence of these precious documents, a remarkable thing happened: a team of librarians and archivists joined forces to spirit the manuscripts into hiding.
