Gormenghast influenced Discworld

Pratchett named Peake among the writers who formed him, and Ankh-Morpork owes Gormenghast more than it owes any secondary world with elves in it. Both are governed by ritual nobody remembers the purpose of, administered by functionaries who outrank their masters in practice, in a structure so old it has become geography. The Patrician's clerks and the Unseen University's committees are Barquentine's ledgers played for comedy rather than dread.
