The image above represents a replica of the wooden horse made by the Greeks during the war against Troy. It was Odysseus' idea to hide soldiers inside the horse. The horse was offered to the Troyans as a religious gift so that the citizens of Troy could not refuse it. With the horse, the Greeks soldiers could enter the city and win the war. The replica depicted above is conserved in Turkey.

Odysseus

The famous Greek hero, Odysseus, was known to Romans as Ulysses. Odysseus was the king of Ithaca, a small island in the Ionian sea, where he lived with his wife Penelope. After fighting the war at the city of Troy, Odysseus tried to sail back home.

During his journey he had many amazing adventures, but his brain helped him to survive. After ten years of traveling, he finally reached his house.

Because of Odysseus' long journey to reach his home, a NASA space mission has been named after his better known Roman name: The Ulysses mission.
