“Tech.  And, mighty Tamburlaine, our earthly God, Whose looks make this inferior world to quake, I here present thee with the crowne of Fesse, And with an hoste of Moores trainde to the war, Whose coleblacke faces make their foes retire, And quake for feare, as if infernall Ioue, Meaning to aid them in this Turkish armes, Should pierce the blacke circumference of hell, With vgly Furies bearing fiery flags, And millions of his strong tormenting word. (1.6)”

The passage to the crowne by murder made, Abdallas dies, and deisnes this tyrant king, Of whome we treate sprong from the Arabian moore Blacke in his looke, and bloudie in his deeds, And in his shirt staind with a cloud of gore, Presents himselfe with naked sword in hand, Accompanied as now you may behold, With deuils coted in the shapes of men.

I cannot ride through the Castilian streets But thousand eies through windows, and through doors Throw killing looks at me, and every flave At Eleazar darts a finger out, And every hissing tongue cries, There’s the Moor, That’s he that makes a Cuckold of our King,there go’s the Minion of the Spanish Queen; That’s the black Prince of Divels.

“By the later Middle Ages, Europeans used the word “Saracen” as a pejorative term for any Muslim. However, there was also a racial belief current at the time that Saracens were blackskinned. The Muslims didn’t take this insulting name lying down, however. They had their own none-too-complimentary term for the European invaders, as well. To the Europeans, all Muslims were Saracens. And to the Muslim defenders, all Europeans were Franks (or Frenchmen) — even if those Europeans were English.”
