Ulysses is the hero of the Odyssey, written by the Greek poet Homer in the 8th century BC.
He is a figure from Greek mythology, which tells stories about war between humans and the gods.
In ancient times, the Greeks believed these historic epic poems.
Did Ulysses really exist?
No, because mythology is a collection of legends.
Ulysses is famous for having had the idea, during the Trojan War, to hide inside a giant wooden horse with his army to attack the Trojans by surprise.
The Odyssey recounts his adventures on the way home to Ithaca, where he was king, and where his wife Penelope and his son Telemachus were waiting.
The god Poseidon does everything to stop Ulysses from getting home because he had blinded his son Polyphemus, the Cyclops.
