The following extract has been taken from a manuscript penned by Farthing himself and understood to be the introduction to his lost and unpublished treatise on the holy bloodline, the Sangraal Germanus. Alexander Farthing was the notably eccentric, if not deranged founder and Chief Librarian of the astonishing bibliotheca of Chalisbury from 1714, when a certain John Erskine sponsored the establishment of both the library and Farthing's raison dêtre. His sudden, strange and unexplained disappearance in February 1746 caused much speculation within the circles of intelligentsia of the United Kingdom.

Greetings fellow erudite philosophers.
My name is Alexander Farthing, Librarius Occultus, the enigmatic founder and eternal bibliographer incognita to the Great Library of Chalisbury, the most influential collection of documented wisdom since Alexandria itself.
I take advantage of my privileged position for good cause and fleetingly take leave of my perceived duties, from the endless preoccupation of my subterranean sanctuary, and entreat you to explore this most vital and fundamental work, which is, I assure you, off the greatest import to mankind…

It is not known if the manuscript was ever completed, or if any other portions remain intact and undiscovered.
