I left hurriedly, the precious prize under my arm. What a find! I had heard of this book before. Ludvig Prinn was its author; he who had perished at the inquisitorial stake in Brussels when the witchcraft trials were at their height. A strange character—alchemist, necromancer, reputed mage—he boasted of having attained a miraculous age when he at last suffered a fiery immolation at the hands of the secular arm. He was said to have proclaimed himself the sole survivor of the ill-fated ninth crusade, exhibiting as proof certain musty documents of attestation. It is true that a certain Ludvig Prinn was numbered among the gentlemen retainers of Montserrat in the olden chronicles, but the incredulous branded Ludvig as a crack-brained impostor, though perchance a lineal descendant of the original warrior.
