John Gower (; c. 1330 – October 1408) was an English poet, a contemporary of William Langland and the Pearl Poet, and a personal friend of Geoffrey Chaucer. He is remembered primarily for three major works, the Mirour de l'Omme, Vox Clamantis, and Confessio Amantis, three long poems written in French, Latin, and English respectively, which are united by common moral and political themes.
Few details are known of Gower's early life. He was probably born into a family which held properties in Kent and Suffolk.:299 Stanley and Smith use a linguistic argument to conclude that "Gower’s formative years were spent partly in Kent and partly in Suffolk". Southern and Nicolas conclude that the Gower family of Kent and Suffolk cannot be related to the Yorkshire Gowers because their coats of arms are drastically different.:111 Macaulay:xxx-xxxiii and other critics have observed that he must have spent considerable time reading the Bible, Ovid, Secretum Secretorum, Petrus Riga, Speculum Speculationum, Valerius Maximus, John of Salisbury, and others.
He once met Richard II. In the prologue of the first recension of the Confessio Amantis, he tells how the king, chancing to meet him on the Thames (probably circa 1385), invited him aboard the royal barge, and that their conversation then resulted in a commission for the work that would become the Confessio Amantis. Later in life his allegiance switched to the future Henry IV, to whom later editions of the Confessio Amantis were dedicated. Much of this is based on circumstantial rather than documentary evidence, and the history of revisions of the Confessio Amantis, including the different dedications, is yet to be fully understood.
The source of Gower's income remains a mystery.:198 He may have practised law in or around London. George Campbell Macaulay lists several real estate transactions to which Gower was a party.:xi Macaulay's Introduction to the French Works suggests that Gower may have been a dealer in wool.:xiii This is based on remarks from Mirour d l'Omme line 25360ff. From 1365 he received ten pounds' rent for the manor of Wygebergh in Essex.:xi From 1382 until death he received forty pounds per annum from selling Feltwell in Norfolk and Moulton in Suffolk.:117 In 1399 Henry IV granted him a pension, in the form of an annual allowance of two pipes (= 1 tun = 240 gallons) of Gascony wine. Carlson estimates the value of the two pipes as 3 to 4 pounds wholesale or 8 pounds retail.:199
Gower's friendship with Chaucer is also well documented. When Chaucer was sent as a diplomat to Italy in 1378, Gower was one of the men to whom he gave power of attorney over his affairs in England.:xv The two poets also paid one another compliments in their verse: Chaucer dedicated his Troilus and Criseyde in part to "moral Gower", and Gower reciprocated by placing a speech in praise of Chaucer in the mouth of Venus at the end of the Confessio Amantis (first recension VIII.2950-70). The Introduction to the Man of Law's Tale (lines 77–89) contains an apparent reference to Gower's tales of Canacee and Tyro Appolonius. Tyrwhitt (1822) believed that this offended Gower and led to the removal of Venus’ praise of Chaucer. Twentieth century sources have more innocent reasons for the deletion.:xxvi-xxviii
At some point during the middle 1370s, he took up residence in rooms provided by the Priory of St Mary Overie (now Southwark Cathedral).:59 In 1398, while living here, he married,:xvii probably for the second time: his wife, Agnes Groundolf, who survived him. In his last years, and possibly as early as 1400, he became blind.:300
After his death in 1408, Gower was interred in an ostentatious tomb in the Priory church (now Southwark Cathedral), which remains today.
Macaulay provides much information and speculation about Gower. Some of his conclusions are inferences drawn from the trilingual writings of Gower. Where possible he draws upon legal records and other biographers.
Gower's verse is by turns religious, political, historical, and moral—though he has been narrowly defined as "moral Gower" ever since Chaucer graced him with the epithet.:line 1856 His primary mode is allegory, although he shies away from sustained abstractions in favour of the plain style of the raconteur.
His earliest works were probably ballades in Anglo-Norman French, some of which may have later been included in his work the Cinkante Ballades. The first work which has survived is in the same language, however: it is the Speculum Meditantis, also known by the French title Mirour de l'Omme, a poem of just under 30,000 lines, containing a dense exposition of religion and morality. According to Yeager "Gower's first intent to write a poem for the instructional betterment of king and court, at a moment when he had reason to believe advice about social reform might influence changes predictably to take place in an expanded jurisdiction, when the French and English peoples were consolidated under a single crown."
Gower's second major work, the Vox Clamantis, was written in Latin. The first book has an allegorical account of the Peasants' Revolt which begins as an allegory, becomes quite specific and ends with an allusion to William Walworth’s suppression of the rebels.:xxxiv-xl Gower takes the side of the aristocracy but the actions of Richard II are described by "the captain in vain endeavoured to direct the ship’s course".:xxxixSubsequent books decry the sins of various classes of the social order: priests, friars, knights, peasants, merchants, lawyers. The last two books give advice to King Richard II and express the poet's love for England.:xxx-lvii As Gower admits, much of Vox Clamantis was borrowed from other authors. Macaulay refers to this as "schoolboy plagiarism":xxxii Peter classifies Mirour and Vox as "complaint literature" in the vein of Langland.
His third work is the Confessio Amantis, a 30,000-line poem in octosyllabic English couplets, which makes use of the structure of a Christian confession (presented allegorically as a confession of sins against Love) as a narrative frame within which a multitude of individual tales are told.:I.203–288 Like his previous works, the theme is very much morality, even where the stories themselves have a tendency to describe rather immoral behaviour. One scholar asserts that Confessio Amantis "almost exclusively" made Gower's "poetic reputation."
Fisher views the three major works as "one continuous work" with In Praise of Peace as a capstone. There is "movement from the courtly tone of the Cinkante Balades to the moral and philosophical tone of the Traitie." Leland  (ca 1540) :Fisher translation 136 states "that the three works were intended to present a systematic discourse upon the nature of man and society."
They provide as organized and unified a view as we have of the social ideals on England upon the eve of the Renaissance. This view may be subsumed under the three broad headings: individual VIRTUE, legal JUSTICE, and the administrative responsibility of the KING. The works progress from the description of the origins of sin and the nature of the vices and virtues at the beginning of the Mirour de l'omme, through consideration of social law and order in the discussion of the three estates in the Mirour and Vox Clamatis, to a final synthesis of royal responsibiity of Empedoclean love in the Confessio Amantis.:136
In later years Gower published a number of minor works in all three languages:
Critics have speculated on which late work triggered the royal wine allowance mentioned in the Life section. Candidates are Cronica tripertita,:26 In Praise of Peace,:85 O Recolende or an illustrated presentation copy of Confessio with dedication to Henry IV. According to Meyer-Lee "no known evidence relates the collar or grant [of wine] to his literary activity."
Gower's poetry has had a mixed critical reception. In the 16th century, he was generally regarded alongside Chaucer as the father of English poetry.:ix In the 18th and 19th centuries, however, his reputation declined, largely on account of a perceived didacticism and dullness; e.g. the American poet and critic James Russell Lowell claimed Gower "positively raised tediousness to the precision of science".:329 After publication of Macaulay's edition (1901) of the complete works, he has received more recognition, notably by C. S. Lewis (1936), Wickert (1953), Fisher (1964), Yeager (1990)  and Peck (2006).  However, he has not obtained the same following or critical acceptance as Geoffrey Chaucer.
When Wickert was attempting to date Vox Clamantis Books Two to Seven, she found two passages which predict the revolt. One is Mirour(lines 26485-26496) which uses the metaphor of the stinging nettle to predict the impending catastrophe. The second is the final couplet of Vox Clamantis Book Five Chapter 10.(line V.563-564) This predicts trouble in a short time.:18–19 Gower's warnings and call for reform were ignored both before and after the events of 1381.:51–52
Chaucer used octosyllabic lines in The House of Fame but eschewed iambic rhythm. He "left it to Gower to invent the iambic tetrameter, and to later centuries of poets to solve the problems of its potential monotony; he himself merely polished the traditional Middle English short line.":85
Fisher :207 concludes that they were living near each other in the period 1376 to 1386. They influenced each other in several ways:
Sebastian Sobecki's discovery of the early provenance of the trilingual Trentham manuscript reveals Gower as a poet who was not afraid to give Henry IV stern political advice. Sobecki also claims to have identified Gower's autograph hand in two manuscripts.
