Just in case you're looking for something delightfully weird to bake this season, here's a lovely long blog post about how to make cuneiform gingerbread. The post is from last year, but hey, what's a year more or less when talking about ancient cuneiform scripts?

And in case you don't want to copy an existing text, there's alternatives to this. First of all, an online transcribing gadget that will give out your own text in cuneiform script. Or you can check out the twitter feed of Team Cooleiform, a group of students from Helsinki who have fun doing cuneiform scripts. (I met some of them at the WorldCon in Helsinki, where they made clay tablets... not transliterated, but actually translated the things you asked for into ancient Sumerian. Which, it turned out, meant a good bit of discussion and checking and thinking when I got my tablet inscribed with "keep flying"...)

So maybe, if you ask nicely, they might even translate something like "this is a cookie" for scribing that onto your gingerbread... who knows?
