To acquire a taste for it is almost to become naturalised in the Middle Ages — C. S. Lewis
From the Carolingian epoch to the end of the Middle Ages and beyond, this was the most widely copied work of secular literature in Europe. It was one of the most popular and influential philosophical works, read by statesmen, poets, and historians, as well as of philosophers and theologians. It is through Boethius that much of the thought of the Classical period was made available to the Western Medieval world. It has often been said Boethius was the “last of the Romans and the first of the Scholastics”.
The philosophical message of the book fits well with the religious piety of the Middle Ages. Readers were encouraged not to seek worldly goods such as money and power, but to seek internalized virtues. Evil had a purpose, to provide a lesson to help change for good; while suffering from evil was seen as virtuous. Because God ruled the universe through Love, prayer to God and the application of Love would lead to true happiness. The Middle Ages, with their vivid sense of an overruling fate, found in Boethius an interpretation of life closely akin to the spirit of Christianity. The Consolation of Philosophy stands, by its note of fatalism and its affinities with the Christian doctrine of humility, midway between the pagan philosophy of Seneca the Younger and the later Christian philosophy of consolation represented by Thomas Aquinas.
The book is heavily influenced by Plato and his dialogues (as was Boethius himself). Its popularity can in part be explained by its Neoplatonic and Christian ethical messages, although current scholarly research is still far from clear exactly why and how the work became so vastly popular in the Middle Ages.
Translations into the vernacular were done by famous notables, including King Alfred (Old English), Jean de Meun (Old French), Geoffrey Chaucer (Middle English), Queen Elizabeth I (Early Modern English), and Notker Labeo (Old High German).
Found within the Consolation are themes that have echoed throughout the Western canon: the female figure of wisdom that informs Dante, the ascent through the layered universe that is shared with Milton, the reconciliation of opposing forces that find their way into Chaucer in The Knight's Tale, and the Wheel of Fortune so popular throughout the Middle Ages.
Citations from it occur frequently in Dante's Divina Commedia. Of Boethius, Dante remarked “The blessed soul who exposes the deceptive world to anyone who gives ear to him.”
Boethian influence can be found nearly everywhere in Geoffrey Chaucer's poetry, e.g. in Troilus and Criseyde, The Knight's Tale, The Clerk's Tale, The Franklin's Tale, The Parson's Tale and The Tale of Melibee, in the character of Lady Nature in The Parliament of Fowls and some of the shorter poems, such as Truth, The Former Age and Lak of Stedfastnesse. Chaucer translated the work in his Boece.
The Italian composer Luigi Dallapiccola used some of the text in his choral work Canti di prigionia (1938). The Australian composer Peter Sculthorpe quoted parts of it in his opera or music theatre work Rites of Passage (1972–73), which was commissioned for the opening of the Sydney Opera House but was not ready in time.
Tom Shippey in The Road to Middle-earth says how “Boethian” much of the treatment of evil is in Tolkien's The Lord of the Rings. Shippey says that Tolkien knew well the translation of Boethius that was made by King Alfred and he quotes some “Boethian” remarks from Frodo, Treebeard and Elrond.
Boethius and Consolatio Philosophiae are cited frequently by the main character Ignatius J. Reilly in the Pulitzer Prize-winning A Confederacy of Dunces (1980).
Boethius is also referenced in the 2002 film 24 Hour Party People, when Tony Wilson's character is recited an excerpt of "The Consolation of Philosophy" by a panhandler to whom he has just given pocket change. This reference is related to viewing history as a wheel, with the fortunes of man rising and falling as cyclically as its spokes. It speaks largely to the wheel's allegorical metaphor to the vicissitudes of life.
It is a prosimetrical text, meaning that it is written in alternating sections of prose and metered verse. In the course of the text, Boethius displays a virtuosic command of the forms of Latin poetry. It is classified as a Menippean satire, a fusion of allegorical tale, platonic dialogue, and lyrical poetry.
In the 20th century there were close to four hundred manuscripts still surviving, a testament to its former popularity.
