The Chaucer Review: An Indexed Bibliography (Vols. 1-30)

Krochalis, Jeanne E. "Hoccleve's Chaucer Portrait." 21 (1986): 234-45.
Portraits of authors existed in classical times, and medieval manuscripts also included portraits of authors, but these portraits often did not reflect the physiognomy of the author. Indeed, scribes and authors have the same features. Hoccleve memorializes Chaucer in his Regement of Princes and, in so doing, equates him with the rich and holy who could afford to be memorialized in effigy or in verse.

Miller, Miriam Youngerman. "Illustrations of the Canterbury Tales for Children: A Mirror of Chaucer's World." 27 (1993): 293-304.
Though most scholars appreciate the depiction of medieval life found in works such as the Wilton diptych and in the portraits of the pilgrims in the Ellesmere manuscript, most nineteenth- and twentieth-century illustrators have prefered contemporary styles, using art nouveau and historicism. Modern illustrators often stray far from the descriptions of the pilgrims in the General Prologue and ignore descriptive details from the tales themselves. The illustrators discussed range from Mrs. Harveis (1882) to Reg Cartwright.
