On Clint's birthdate: James Dean and Elvis weren't born yet. Wonder Bread started selling sliced bread a year prior. Chocolate chip cookies didn't exist. Picasso was the same age as Charlize Theron right now. The first documented high five wouldn't occur for another 46 years.
This was made over 250 years before Achilles slew Hector. Over 1000 years before the publication of Plato’s Republic. Literally an unthinkable level of craftsmanship for the time.
