Ah, well, Thoth understood the explanation given as far as why the closer viewing of the sphinx project wouldn't wait until nightfall and didn't begrudge that at all. The moon. That was a very important duty. Certainly each peoples had their own god or goddess of the moon, and that duty was not something that could be ignored for personal satisfaction of curiosity. There was a higher responsibility.
So Thoth nodded in understanding, smiled and clapped Nanna on the back before said, “Yes. Come. See sphinx now.” From here he led him closer. As long as they stayed invisible to mortal eye, there should be no undo fears on the part of those doing the construction.
He had no reservations about the Sumerian coming back tomorrow for another look and more beer. Thoth actually had the suspicion that he and this god would get along wondrously, once they got past the language barrier. Which meant overnight, he was going to look through his parchments and tablets and see if there was anything more in them about the language of this Sumerian.
