Following the publication of the facsimile and transcription, G. Herdan published an article in which he concluded, based upon the percentage of words in the "Equatorie" of "Romance vocabulary" (which includes words from Old French, Anglo-Norman French, and Latin), that Chaucer was indeed the author: "The agreement between observation and expectation, or between fact and theory, is so striking that without going further into the question of statistical significance we may conclude that by the token of Romance vocabulary the "Equatorie" is to be regarded as a work by Chaucer".
