Reddit mentions of Gilgamesh the King (The Gilgamesh Trilogy)

The Epic of Gilgamesh was discovered (but not deciphered) by an Assyrian archeologist, Hormuz Rassam who was the first non-European archeologist from the Middle East.

I recently read the Epic of Gilgamesh, and I highly recommend it if you haven't read it already, I really enjoyed this edition by penguin classics. Although the side material in this translation was also nice.

It's also a great gift to give to someone, and for kids I recommend this trilogy (just make sure to buy all three) by Ludmilla Zeman. It is beautifully illustrated with many pictures and was appreciated by the kids.

Edit: Haha, seems like a Chaldean hardliner has changed Hormuzd Rassam's wiki page and now it says Chaldean, it used to say Assyrian.

Although not really a compilation of myths, I read [this] (http://www.amazon.com/Gilgamesh-King-Trilogy-Ludmila-Zeman/dp/0887764371/ref=sr_1_3?s=books&ie=UTF8&qid=1413947341&sr=1-3&keywords=Gilgamesh) Gilgamesh trilogy with a couple of my students interested in that era and they really dug it. It's an Uruk myth, of course, but pretty prevalent in Mesopotamia in general.

That actual source material (or rather translations of it) is pretty fascinating as well if you've never read it, though not so kid-friendly.

There is actually 3 children's books that are pretty much written for 5 year olds. They're pretty amazing.
