No one else not even loveritas, an opinion I actually respect, recognized they were not Greek.
I did. I knew right away they weren't Greek or Roman numbers, and they had to be numbers since it is a nilometer. Probably because I've scoured ancient scripts the last few years. Just looking at the plaque told me it looked like a modern addition, it didn't look ancient at all. Even the way it is mounted looks like a recent addition.
So now everyone knows now that it is not associated in any way with Puma Punku, which was the unfounded wild speculation in the first place. I noticed that you were not "kind" to your lover (as you were with ck) in calling out her wild assumption based on an internet photo.
