An Ancient Text

is a book in.

Location and Uses
An Ancient Text is found on a table inside Calip's cabin behind Fort Hateno's wall. It provides a riddle about the nearby graveyard, instructing people to pierce a statue's eye at night. This is the key to the Shrine Quest "The Cursed Statue", which is given by Calip. Calip himself studies it every night, though he is unable to discern its meaning. If Link indulges in Calip's desire to be called "Doctor," Calip will directly quote the book for Link, claiming that it's harmless to share the riddle that he has not yet been able to solve.
