John Gower is an author from the 14th century who has been largely forgotten by modern readers. I doubt there are any books, that he wrote currently in print, but Google Books carries a few of them to read online. He was a friend to Geoffrey Chaucer. The Man of Law is thought to be modeled on him since he refers to Gower's story of Apollonius of Tyre in the prologue and the Man of Law's tale is based on one of Gower's stories from Confessio Amantis, Book III. Gower is thought to have been a lawyer.
Gower lived through the arrival of bubonic plague to England in 1348 and the Hundred Years War. He witnessed the Peasants' Revolt, the turmoil of Richard II's reign and his subsequent deposal by Henry IV. Gower wrote Cronica Tripertita about the turbulence of Richard's reign and justifying Henry's usurption of the throne.
If it sounds a little like Milton's Eikonoklastes, you would not wrong to compare the two. Gower has quite a bit in common with Milton: he went blind, he wrote about Biblical themes in English and in Latin (although Gower also wrote in French), they both are unique in writing about Sin being the daughter of Lucifer and Death being the child they created together. Gower precedes Milton by 300 years.
His works include, Speculum Hominis or Mirour de 'omme, Vox Clamantis, Confessio Amantis, Traitie, Cikante Balades, Cronica Tripertita, In Praise of Peace. When I get a chance to do some recreational reading, I will try to post more about him since he truly is an interesting fellow.
