Oriental
Virtual Museum: Some pictures and information, this site also has a
virtual tour of its galleries which must be viewed with Apple QuickTime.
Although the virtual tours are interesting, there's no description of what
you are looking at.
Sumerian
Lexicon: Again, a bit difficult, but if you are interested in really
writing something in cuneiform, you will find at the bottom of this page
links to all their letters and words.
Gateway
to Babylon: Lots of information on myths, religion, gods, magic, hymns
and poems.
