7th-8th century Vettuvan Koil temple, Tamilnadu, India…

de bene esse: literally, of well-being, morally acceptable but subject to future validation or exception

This little known rock cut temple was carved out of single piece of granite stone.

Even today when we have diamond tipped cutting tools it’s a difficult task to carve granite. It's an example of incredible engineering from more than 1300 years ago, and the detail still baffles scholars today.
