I tried various translators I found via google, and most of them gave me the following:
Μια όμορφη δημιουργία
Is that correct? I don't trust these things...
I also highly suspect that this is not Ancient Greek, but I am completely clueless.
To find out how to transcribe these characters, I used this wikipedia-article (german) and came up with this:
mia omorfi dimioyrgia
Please do not throw things at me.
