What is "telemachy"

The Telemachy (from Greek Τηλεμάχεια) is a term traditionally applied to the first four books of Homer's epic poem the Odyssey. They are named so because – just as the Odyssey tells the story of Odysseus – they tell the story of Odysseus' son Telemachus as he journeys from home for the first time in search of news about his missing father.
