We know their names

“And if there shall ever arise a nation whose people have forgotten poetry or whose poets have forgotten the people, though they send their ships round Taprobane and their armies across the hills of Hindustan, though their city be greater than Babylon of old, though they mine a league into the earth or mount to the stars on wings—what of them? They will be but a dark patch upon the world.” – James Elroy Flecker, Hassan: The Story of Hassan of Baghdad and How he Came to Make the Golden Journey to Samarkand
