Edward Daniel Clarke (5 June 1769 – 9 March 1822) was an English naturalist, minerologist, and traveller. (Wikipedia)
One of his bestsellers sold over Europe was Travels in Russia, Tartary and Turkey. The book explains a lot about the formation that calls itself ‘Russia’.
Clarke was a keen observer and one of his many observations was the difference between the Cossacks and Russians:
“In conversation, the Cossack is a gentleman; for he is well
informed, free from prejudice, open, sincere, and upright.
Place him by the side of a Russian—-what « contrast! The
one is literally a two-legged pig, having all the brutality, but
more knavery, than that animal…”
