John Bale attributed "The Courte of Venus" and "The Pilgrim's Tale" to Chaucer in his "Illustriam maioris scriptores...summarium", noting that he saw a quarto edition of "The Courte of Venus" that included "The Pilgrim's Tale", probably Gibson's printed edition of ca. 1536–1540. However, Bale changed the ascription of authorship for "Curiam Veneris" (his Latin name for "The Courte of Venus") to Robert Shyngleton/Singleton ("Robertus Shyngleton, astrorum et theologie peritus, sacerdos, composuit") in his notes in "Index Britanniae scriptorum", although his later, 1559 edition of the "Illustriam" kept it as Chaucer's. It is possible that Shyngleton was the compiler of "The Courte of Venus" and probably the author of its Prologue (in the Douce fragment) as well as "The Pilgrim's Tale". Little is known about Shyngleton, except that he was an Oxford-educated Roman Catholic divine, who may not have graduated. He may have become a Protestant; he was for a time a chaplain to Anne Boleyn, who was sympathetic to the English Protestants. He was tried for treasonable utterances in 1543 and hanged in 1544 with Germain Gardiner and John Larke, an event recorded in John Foxe's "Actes and Monuments". Bale recorded that Shyngleton was said to have written a "Treatise of the Seven Churches"; "Of the Holy Ghost"; "Comment on Certain Prophecies"; and "Theory of the Earth", which was dedicated to Henry VII and has elsewhere been called "Of the Seven Ages of the World". None of these texts exist in print, but Bale wrote that Gibson printed "Shyngleton's De VII Ecclesiis and De Spiritu."
