Robert de Gretham
Robert de Gretham was a thirteenth-century English poet. Little is known about his life, but his legacy survives in the Miroir or Evangiles des Domnees in which Robert turned sermons into verse. The poem offered the reader a template of best moral practices to emulate or reflect—in other words, the text was a “spiritual mirror.”  Robert was commissioned to write it for the lady Aline as alternative reading material to the extremely popular genre of romances. There are seven complete manuscripts of the Anglo-Norman French text and four extant manuscripts of its English translation. Look at the poetry section for more on medieval poems.
