This is truly amazing. I love it!

Found a minor nit — the entry for “shoe” is at 3500 BCE and links to the Wikipedia article for “sandal”. But the Wikipedia article for “shoe” [1] indicates that the earliest shoes (apparently not sandals) were worn around 7000-8000 BCE.

The links were mixed up (fixed now!) but I think the dates were correct; 3,500 BC is the date of the first leather shoe known, in Armenia.
