Eisner, Sigmund. "Canterbury Day: A Fresh Aspect." 27 (1992): 31-44.
References in the text clearly indicate that the pilgrimage to Canterbury took place on a single day. Given the information in the text, and in the Equatorie of the Planetis, the Treatise on the Astrolabe, and Nicholas Lynn's Kalendarium, the date and year of the pilgrimage can be fixed as April 18, 1394.
Krochalis, Jeanne E. "Postcript: The Equatorie of the Planetis as a Translator's Manuscript." 26 (1991): 43-47.
Insertions, corrections, and glosses in Latin suggest that the scribe was translating the Equatorie of the Planetis, checking his work as he progressed.
Robinson, Pamela. "Geoffrey Chaucer and the Equatorie of the Planetis: The State of the Problem." 26 (1991): 17-30.
A combination of evidence suggests that Chaucer did indeed write the Equatorie of the Planetis. The notation "Radix chaucer" in light of the dated calculations, the sloppiness of the copy, the format of the text, diagrams, evidence that the work remained a loose parchment for some time, and the possessive form preceding the date 1392 all suggest that Chaucer was indeed the author. Orthography supports the view that Chaucer, the poet, was the author of this text.
