The god of love, a benedicite!
How myghty and how greet a lord is he!
Ayeyns his myght ther gayneth none obstacles.
He may be cleped a god for his myracles,
For he kan maken, at his owene gyse,
Of everich herte as that hym list divyse.

– Geoffrey Chaucer

The Canterbury Tales, The Knight’s Tale. Theseus says that the god of love is mighty and all-powerful and can make every heart do whatever he pleases. He is referring to Arcite and Palamon, who have risked death and the wrath of Theseus for the love of a woman.
