Emile by Jean-Jacques Rousseau: “Her mother took the book and opened it; it was The Adventures of Telemachus.”
The Just City by Jo Walton: “It happened to a bound copy of Aeschylus's Telemachus. (text attributes it in-story to Aeschylus, but the real published 'Telemachus' — a prose sequel to the Odyssey — is by Fénelon)”
Pamela by Samuel Richardson: “What are you reading? Sir, said he, and stammered with the surprise, it is the French Telemachus; for I am about perfecting myself, if I can, in the French tongue.”
Paul and Virginia by Bernardin de Saint-Pierre: “Thus, no book gave him so much pleasure as Telemachus, from the pictures it draws of pastoral life, and of the passions which are most natural to the human breast.”
