Which Discworld novel by Sir Terry Pratchett features the character Horace?

Answer 1

The question may refer to Horace Worblehat, The Librarian of Unseen University, Horace the Senior Wrangler on the staff of Unseen University, or Horace the Cheese.

The Librarian first appeared in the first novel of the series, The Colour of Magic, and was transformed into an orangutan in "The Light Fantastic" as the Octavo fired a beam of magic upwards (a sort of systemwide, in this case universe-wide, update intended to save the Eighth Creation Spell (and thus Rincewind) from falling off the disc). The Librarian's actual name has never been given in any of the books; he is always simply "the Librarian". If the Librarian's true name were known, he could be changed back into a human, and he has carefully excised his name from the records of the University (since he has special access). The Discworld Companion hints that he may once have been Dr. Horace Worblehat, which goes a long way to explaining why he's happier as an orangutan than as a human. The Art of Discworld confirms that the Librarian was indeed Dr. Horace Worblehat, and that his fears of turning back into human are baseless at most - although with such a name, one could only surmise that he has a past to which he doesn't want to go back. Rincewind is apparently the only wizard who still remembers the Librarian's name, but agreed not to tell anyone.

Horace the Senior Wrangler is a character in The Hogfather, The Last Continent, and the short story A Collegiate Casting-Out of Devilish Devices written by Sir Pratchett. He also appears in the Discworld video game. Apparently a senior wrangler can be a wise philosopher or a man who looks after horses. The Senior Wrangler of the University encompasses both - he is a philosopher who looks like a horse. While wizards on the Disc are normally celibate, he briefly tries to romance the Cheerful Fairy in Hogfather, and during the events of The Last Continent seems hopelessly infatuated with Mrs. Whitlow, the matronly head of housekeeping at Unseen University.

Horace is also the name of a large, ambulatory Lancre Blue cheese created by Tiffany Aching. Tiffany is the main character in the books The Wee Free Men, A Hat Full of Sky and Wintersmith and Horace appears in these books. Horace the cheese has the peculiar habit of eating mice. Daft Wullie, a Nac Mac Feegle (aka pictsie) has an affectionate relationship with Horace the Cheese, adopting him as a kind of pet. Horace was made a member of the Chalk Clan of the Nac Mac Feegle in Wintersmith and now sports their tartan.

Answer 2

The character Horace appears in the Discworld novel "Hogfather." Horace is the butler at Unseen University, where he assists the wizards in their various schemes and adventures.
