Your quite welcome!
It's a fascinating book. Some of the traditions are almost (DNA) level into human beings, not literally, but they're really ingrained into some cultures or an inherent part of living that people unconsciously follow.
For instance when i was a kid over my friends house, Philipino's, not Roman or Greek at all, but same idea. His family had almost a shrine room in their house. A separate room with a sort of altar, and photo's of deceased family members. There was no emphasis on an eternal flame, per se but they had candles, etc. and the light shown through the window in a soft diffuse way that was beautiful. Made a big impression on me as a 12 year old. I just took it as some type of cultural thing I didn't quite understand but deep in my bones I felt it very fitting and "right".
A couple years ago after I found and read
The Ancient City I saw that my Mom has a corner desk with photo's of family members that while not an hearth/shrine fills that function (sort of) in her house. I bet a lot of people do these things unconsciously.
So I began to notice things after reading the book.
It's really an education in human culture and traditions, which made me realize also, the embarrassment of riches in our culture(s). Riches that a venal, crass cult like $cientology deems useless and unimportant because their venal and crass founder says so. What a laugh. Poor a**holes.
