This celebrated portrait of Chaucer occurs in the manuscript at the beginning of the Melibee (with Sir Thopas apparently taken as a kind of prologue to the prose tale). The obvious lack of proportion between the figure of Chaucer and the horse may be due to the use of a tracing of some earlier model. One might compare this portrait to the next earliest, that in Hoccleve's Regiment of Princes click here) and to the Harvard Portrait, which is much later (click here). See Derek Pearsall, Chaucer, for a discussion of all the early portraits of Chaucer.
