This image is in the public domain because it is a representation of an ancient script.
The script itself predates the modern concept of copyright, and the creator of this image has released (or hereby releases) into the public domain any copyright generated by the making of the file (and grants an unconditional licence to anyone, for any jurisdictions in which public-domain release is not legal). This applies internationally and for any purpose.
