The question of whether or not the Epistle is a forgery is controversial among Dante scholars. Scholars such as
Francesco D'Ovidio and have argued against its authenticity, whereas scholars such as ,
Robert Hollander, and
Charles Singleton have argued in favor.
John Ciardi, who wrote a translation of the
Divine Comedy, argued that the framework provided by the letter is useful regardless of its authenticity. The scholar
Teodolinda Barolini has described the Epistle as a
red herring, writing that "frankly, I don't care if the Epistle is Dante's or not, since I think the answers that I seek regarding the [
Divine Comedy] are to be found in the poem itself." In 2019, researchers for the Italian ''
Istituto di Scienza e Tecnologie dell'Informazione'' attempted to use
machine learning to determine authorship of the Epistle. Their results supported the theory that it was forged, though the authors noted that their study "should not be considered conclusive". == References ==
