At the end of the 10th century: the death of Alhakén III has left the caliphate of Córdoba in the hands of Hisham II, an eleven-year-old boy. His guardian, Almanzor, takes advantage of the circumstance to reign in his name. Among his provisions stands out the burning of thousands of volumes from the Córdoba library. Only a few will be saved, on the back of a mule guided by a thief and a couple of slaves. In this masterful graphic novel, screenwriter Wilfrid Lupano and artist Léonard Chemineau write a love letter to knowledge, tolerance, and the achievements of culture as the last barrier to the advance of totalitarianism.
