Tamburlaine
And I have march'd along the River Nile,
To Machda, where the mighty Christian Priest
Cal'd John the great, sits in a milk-white robe.
Whose triple Myter did I take by force,
And made him sweare obedience to my crowne.
As Niayesh (p. 164) points out, these lines, spoken by Tamburlaine's chief lieutenant Techelles, depict Prester John not as a savior to seek out but as an African sovereign to vanquish.
