The Aeneid is a myth poem written by the Roman poet Virgil that describes an origin story about how Rome was founded. It states that Aeneas, son of Aphrodite and Anchises, fled Troy while the Greeks attacked and Troy burned. It then says that he sailed away and founded the city of Rome. The Odyssey is a myth poem written by the Greek writer Homer that tells a tale of the Greek hero Odysseus (also called Ulysses) on his journey in the Trojan War. Odysseus had created a pact with other Greek kings (mentioned in the Iliad) that if Helen of Sparta were to be captured, the Greeks would all save her. So when Helen was captured, Odysseus had no choice but to take his men of Ithaca and go to war. After he left, suitors tried to wed his wife, Penelope but all failed. He encountered many obstacles on his journey, and could even see Ithaca, when an ocean current carried many of his men out to sea, prolonging his return. When he got back, he disguised himself as a beggar to find information about what had happened. Then he attacked the suitors. A bunch of stuff happened (not necessary to your question) and he won back Ithaca.
