In a letter dedicating the volume to Henry, Thynne explains that as "divers imprints" came into his hands, he "easily and without great study might and have
deprehended in them many errours, falsities, and depravation."

(5) With additions and some alterations, the 1532 text remained the basis for all printings of Chaucer's Works until the eighteenth century.
