The International Prester John Project: How A Global Legend Was Created Across Six Centuries

Paradise Lost

John Milton alludes to Prester John indirectly on two occasions in his Paradise Lost (1667). 

In Book IV, the realm of Ethiopia is framed as near the terrestrial paradise and the headwaters of the Nile:

Nor, where Abassin kings their issue guard,
Mount Amara (though this by some suppos'd
True Paradise) under the Ethiop line
By Nilus' head, enclos'd with shining rock,
A whole day's journey high, but wide remote
From this Assyrian garden where the
Fiend Saw undelighted all delight, all kind
Of living creatures, new to sight and strange.

In Book XI, Milton's Adam describes the dissemination of his descendents across the world:

Nor did his eyes not ken
Th'empire of Negus, to his utmost port,
Ercoco, and the less maritime kings,
Mombaza and Quiloa and Melind

This mention of the Ethiopian negus betrays a larger debt Milton paid to Ariosto's Orlando Furioso, argues James H. Sims
