James I and his work The Kingis Quair represent the first phase of Chaucerianism, which purposefully and directly imitates the works of Chaucer while preserving the Scottish author's own uniqueness.
The poems Robert Henryson, William Dunbar, and Gavin Douglas represent the second phase of Chaucerianism, a more academic one, which adapts Chaucer's style to the authors' more individual and nationalistic purposes.
