Richard Pynson, the King's Printer under Henry VIII for about twenty years, was the first to collect and sell something that resembled an edition of the collected works of Chaucer, introducing in the process five previously printed texts that we now know are not Chaucer's. (The collection is actually three separately printed texts, or collections of texts, bound together as one volume.) There is a likely connection between Pynson's product and william Thynne's a mere six years later. Thynne had a successful career from the 1520s until his death in 1546, when he was one of the masters of the royal household. His editions of Chaucers Works in 1532 and 1542 were the first major contributions to the existence of a widely recognised Chaucerian canon. Thynne represents his edition as a book sponsored by and supportive of the king who is praised in the preface by Sir Brian Tuke. Thynne's canon brought the number of apocryphal works associated with Chaucer to a total of 28, even if that was not his intention. As with Pynson, once included in the Works, pseudepigraphic texts stayed within it, regardless of their first editor's intentions.
John Stow (1525–1605) was an antiquarian and also a chronicler. His edition of Chaucer's Works in 1561 brought the apocrypha to more than 50 titles. More were added in the 17th century, and they remained as late as 1810, well after Thomas Tyrwhitt pared the canon down in his 1775 edition. The compilation and printing of Chaucer's works was, from its beginning, a political enterprise, since it was intended to establish an English national identity and history that grounded and authorised the Tudor monarchy and church. What was added to Chaucer often helped represent him favourably to Protestant England.
Probably referring to the 1542 Act for the Advancement of True Religion, Foxe said that he "marvel[s] to consider … how the bishops, condemning and abolishing all manner of English books and treatises which might bring the people to any light of knowledge, did yet authorise the works of Chaucer to remain still and to be occupied; who, no doubt, saw into religion as much almost as even we do now, and uttereth in his works no less, and seemeth to be a right Wicklevian, or else there never was any. And that, all his works almost, if they be thoroughly advised, will testify (albeit done in mirth, and covertly); and especially the latter end of his third book of the Testament of Love … Wherein, except a man be altogether blind, he may espy him at the full: although in the same book (as in all others he useth to do), under shadows covertly, as under a visor, he suborneth truth in such sort, as both privily she may profit the godly-minded, and yet not be espied of the crafty adversary. And therefore the bishops, belike, taking his works but for jests and toys, in condemning other books, yet permitted his books to be read."
Alongside Chaucer's Works, the most impressive literary monument of the period is John Foxe's Acts and Monuments.... As with the Chaucer editions, it was critically significant to English Protestant identity and included Chaucer in its project. Foxe's Chaucer both derived from and contributed to the printed editions of Chaucer's Works, particularly the pseudepigrapha. Jack Upland was first printed in Foxe's Acts and Monuments, and then it appeared in Speght's edition of Chaucer's Works. Speght's "Life of Chaucer" echoes Foxe's own account, which is itself dependent upon the earlier editions that added the Testament of Love and The Plowman's Tale to their pages. Like Speght's Chaucer, Foxe's Chaucer was also a shrewd (or lucky) political survivor. In his 1563 edition, Foxe "thought it not out of season … to couple … some mention of Geoffrey Chaucer" with a discussion of John Colet, a possible source for John Skelton's character Colin Clout.
In his 1598 edition of the Works, Speght (probably taking cues from Foxe) made good use of Usk's account of his political intrigue and imprisonment in the Testament of Love to assemble a largely fictional "Life of Our Learned English Poet, Geffrey Chaucer." Speght's "Life" presents readers with an erstwhile radical in troubled times much like their own, a proto-Protestant who eventually came around the king's views on religion. Speght states that "In the second year of Richard the second, the King tooke Geffrey Chaucer and his lands into his protection. The occasion wherof no doubt was some daunger and trouble whereinto he was fallen by favouring some rash attempt of the Common people." Under the discussion of Chaucer's friends, namely John of Gaunt, Speght further explains:
John Urry produced the first edition of the complete works of Chaucer in a Latin font, published posthumously in 1721. Included were several tales, according to the editors, for the first time printed, a biography of Chaucer, a glossary of old English words, and testimonials of author Writers concerning Chaucer dating back to the 16th century. According to A. S. G Edwards, "This was the first collected edition of Chaucer to be printed in roman type. The life of Chaucer prefixed to the volume was the work of the Reverend John Dart, corrected and revised by Timothy Thomas. The glossary appended was also mainly compiled by Thomas. The text of Urry's edition has often been criticised by subsequent editors for its frequent conjectural emendations, mainly to make it conform to his sense of Chaucer's metre. The justice of such criticisms should not obscure his achievement. His is the first edition of Chaucer for nearly a hundred and fifty years to consult any manuscripts and is the first since that of william Thynne in 1534 to seek systematically to assemble a substantial number of manuscripts to establish his text. It is also the first edition to offer descriptions of the manuscripts of Chaucer's works, and the first to print texts of 'Gamelyn' and 'The Tale of Beryn', works ascribed to, but not by, Chaucer."
Although Chaucer's works had long been admired, serious scholarly work on his legacy did not begin until the late 18th century, when Thomas Tyrwhitt edited The Canterbury Tales, and it did not become an established academic discipline until the 19th century. Scholars such as Frederick James Furnivall, who founded the Chaucer Society in 1868, pioneered the establishment of diplomatic editions of Chaucer's major texts, along with careful accounts of Chaucer's language and prosody. Walter william Skeat, who like Furnivall was closely associated with the Oxford English Dictionary, established the base text of all of Chaucer's works with his edition, published by Oxford University Press. Later editions by John H. Fisher and Larry D. Benson offered further refinements, along with critical commentary and bibliographies.
One other significant work of Chaucer's is his Treatise on the Astrolabe, possibly for his own son, that describes the form and use of that instrument in detail and is sometimes cited as the first Example of technical writing in the English language. Although much of the text may have come from other sources, the treatise indicates that Chaucer was versed in science in addition to his literary talents. Another scientific work discovered in 1952, Equatorie of the Planetis, has language and handwriting similar to some considered to be Chaucer's and it continues many of the ideas from the Astrolabe. Furthermore, it contains an Example of early European encryption. The attribution of this work to Chaucer is still uncertain.
With the textual issues largely addressed, if not resolved, attention turned to the questions of Chaucer's themes, structure, and audience. The Chaucer Review was founded in 1966 and has maintained its position as the pre-eminent journal of Chaucer studies.
Chaucer wrote in continental accentual-syllabic meter, a style which had developed since around the 12th century as an alternative to the alliterative Anglo-Saxon metre. Chaucer is known for metrical innovation, inventing the rhyme royal, and he was one of the first English poets to use the five-stress line, a decasyllabic cousin to the iambic pentameter, in his work, with only a few anonymous short works using it before him. The arrangement of these five-stress lines into rhyming couplets, first seen in his The Legend of Good Women, was used in much of his later work and became one of the standard poetic forms in English. His early influence as a satirist is also important, with the Common humorous device, the funny accent of a regional dialect, apparently making its first appearance in The Reeve's Tale.
Speght is also the source of the famous tale of Chaucer being fined for beating a Franciscan friar in Fleet Street, as well as a fictitious coat of arms and family tree. Ironically—and perhaps consciously so—an introductory, apologetic letter in Speght's edition from Francis Beaumont defends the unseemly, "low", and bawdy bits in Chaucer from an elite, classicist position. Francis Thynne noted some of these inconsistencies in his Animadversions, insisting that Chaucer was not a commoner, and he objected to the friar-beating story. Yet Thynne himself underscores Chaucer's support for popular religious reform, associating Chaucer's views with his father william Thynne's attempts to include The Plowman's Tale and The Pilgrim's Tale in the 1532 and 1542 Works.
In the 16th and 17th centuries, Chaucer was printed more than any other English author, and he was the first author to have his works collected in comprehensive single-volume editions in which a Chaucer canon began to cohere. Some scholars contend that 16th-century editions of Chaucer's Works set the precedent for all other English authors in terms of presentation, prestige and success in print. These editions certainly established Chaucer's reputation, but they also began the complicated process of reconstructing and frequently inventing Chaucer's biography and the canonical list of works which were attributed to him.
Widespread knowledge of Chaucer's works is attested by the many poets who imitated or responded to his writing. John Lydgate was one of the earliest poets to write continuations of Chaucer's unfinished Tales while Robert Henryson's Testament of Cresseid completes the story of Cressida left unfinished in his Troilus and Criseyde. Many of the manuscripts of Chaucer's works contain material from these poets and later appreciations by the romantic era poets were shaped by their failure to distinguish the later "additions" from original Chaucer. Writers of the 17th and 18th centuries, such as John Dryden, admired Chaucer for his stories, but not for his rhythm and rhyme, as few critics could then read Middle English and the text had been butchered by printers, leaving a somewhat unadmirable mess. It was not until the late 19th century that the official Chaucerian canon, accepted today, was decided upon, largely as a result of Walter william Skeat's work. Roughly seventy-five years after Chaucer's death, The Canterbury Tales was selected by William Caxton to be one of the first books to be printed in England.
Geoffrey Chaucer’s attitudes toward “the Church” should not be confused with his attitudes toward Christianity. Chaucer seems to have respected and admired sincere Christians (and to have been one himself), even while he also recognized that many people in the church of his era were venal and corrupt. In his "retraction" Chaucer writes "now I beg all those that Listen to this little treatise [Canterbury Tales], or read it, that if there be anything in it that pleases them, they thank our Lord Jesus Christ for it, from whom proceeds all understanding and goodness."
