Really amazing. I find this sort of thing absolutely haunting. It's a vivid reminder that there is nothing particularly special about this moment in time: it's only special to us because we're living it. But their present moment was no less vital and immediate and real to them as this moment is to us. And yet, it happened so incredibly long ago!
I had the same feeling when I encountered a beautiful statue of a woman that was created in ancient Egypt. It was in a museum and I lingered at the display case, essentially just gazing into her eyes. Her personality shone through in some undefinable way: it felt like encountering another human being across an incredible expanse of time.
These moments, I find, are very poignant in the way they remind us of our own mortality — but also our deep connection to our ancestors and to the past.
