Answer: The words provided are pronouced by Athena in The Odyssey. She seeks to convince Telemachus to start a long journey in search of the truth about his father, Odysseus.
Explanation: Throughout The Odyssey, Athena acts as the advisor of Odysseus and his son, Telemachus. In Book 1, the goddess, who has taken the disguise of Mentor, tells Telemachus that it is time to grow up and to abandon his resentment against his father for having left him and Penelope. Moreover, she tries to convince Telemachus to embark on a long journey in order for him to find out what happened to Odysseus. In order to persuade Telemachus, Athena makes reference to Prince Orestes' bravery ("(...) Haven't you heard what glory Prince Orestes won throughout the world when he killed that cunning, murderous Aegisthus (...)").
