I have to admit I squee'd when I saw a small tablet inscribed with the epic tale of Gilgamesh in cuneiform. I think that was the highlight of the exhibit for me. Another really cool piece was this large granite sculpture with Hammurabi's code of laws written on it. Did I mention all the fabulous semi precious stone jewelry? Carnelian and Lapis Lazuli etc. One of the early excavation dig leader had a necklace made out of cylinder seals.....gorgeous if a bit extravagant even for me!
I'd recommend you go before the exhibit's over (Jan 5, 2013.) You will not be disappointed!
