“On the eleventh day, in the morning, Ab-Hakek was not yet dead. A noise of heavy footsteps was heard in the stairwell of the turret. The door opened: a phantasmagoric and portentous being entered. It was Agraman. 

“At the sight of him, the magician, burdened and statue-like as he was, stood up. ‘I am hungry!’ he murmured, ‘I am going to die: it is time to tell me the last word of science.’

“Agraman took him by the wrist and shouted in his ear, with a violent and metallic burst of laughter: ‘Master! Science is the shadow of a shadow: umbra umbræ!’”

Alphonse Esquiros, 1838
