Name: Gilgamesh flood tablet

What it is: Also known as the 11th tablet of the Epic of Gilgamesh, this fragment of a baked clay tablet contains cuneiform inscriptions describing an epic flood that swept through Babylon. It is considered one of the oldest pieces of literature in the world.

Where it was found: Nineveh (also known as Kouyunjik), an ancient Assyrian city in Upper Mesopotamia (present-day Iraq).

When it was made: The Epic of Gilgamesh may date to as early as the third millennium B.C., but this particular tablet dates to the seventh century B.C.

What it tells us about the past: The epic tale that was carved into the ancient tablet is eerily similar to the biblical story of Noah's ark found in the Book of Genesis. The tablet describes how the gods sent a flood down to destroy Earth. However one god, Ea, alerts Utu-napishtim, the ruler of an ancient kingdom, of the plan and instructs him to build a boat to save himself and his family along with "birds and beasts of all kinds," according to the British Museum, which counts the artifact as part of its permanent collection.

Just like in the Book of Genesis, the voyagers release birds to see if the waters had receded enough for land to emerge. Later, Utu-napishtim tells Gilgamesh of his experience, according to the text.

Archaeologists discovered the roughly 6-by-5-inches (15 by 13 centimeters) tablet in the late 1800s but were unsure of what the inscription said. After handing over the artifact to the museum, a researcher named George Smith deciphered the text and allegedly said, "I am the first man to read that after more than two thousand years of oblivion," according to Smithsonian.

While this tablet was the first evidence of the Noah story coming from another culture, archaeologists have since discovered much older cuneiform tablets with similar flood stories that suggest the story had been circulating long before the Hebrew bible was written. In other words, the Epic of Gilgamesh may have been the source of the Noah's ark story.
