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

Baird, Joseph L., and Lorrayne Y. Baird. "Fabliau Form and the Hegge Joseph's Return." 8 (1973): 159-69.
Most of the Joseph plays show Joseph as an impotent old man with a young wife, but only the Hegge dramatist draws direct attention to the fabliau-love-triangle possibilities of this view. Examination of the Hegge Joseph's Return shows that it followed the lover's triangle pattern, borrowing the unexpected entrance of the husband, his loss of sight, discovery of the wife, her strategic escape from a difficult situation, and the husband's repentance and acceptance of the situation with joy.

Bleeth, Kenneth. "Joseph's Doubting of Mary and the Conclusion of the Merchant's Tale." 21 (1986): 58-66.
The end of the Merchant's Tale in which January regains his sight parallels the end of the story of Joseph and Mary, told in the Cherry-Tree Carol and Ludus Coventriae, where Joseph is enlightened with regard to the spiritual nature of Mary's pregnancy. May's explanation of her behavior in terms of January's blindness is an ironic reversal of Joseph's response to Mary. Both January and Joseph apologize, and both finally respond to the pregnancy by stroking the womb of their wives. But in the end Joseph has been enlightened, whereas January refuses to perceive.
