 A detailed comparison between the surviving Italian and Spanish texts shows numerous places where the Spanish reading appears to be secondary, as for example, where a word or phrase necessary for the meaning is missing in the Spanish text but present in the Italian.Bernabé Pons, arguing for the priority of the Spanish version, maintains that these are due to transcription errors accumulating through the stages of creating the Sydney manuscript, which is a copy of a copy.Joosten, however, while accepting that the carelessness of the two successive English copyists is the most likely explanation for most such instances, nevertheless argues that a minority of such readings are inherently more likely to be due to translation errors in the Spanish text.
