E. R. Smits, like André Vernet (1938), hypothesizes that Carnotensis (the pen-name of the commentary) is Bernard of Chartres – the individual who Silvestris is most confused for. Vernet says that Silvestris, for whom this confusion was normally detrimental, probably gained from this particular confusion, as he is most often credited for the commentary on Vergil's "Aeneid". Smits and Vernet attribute Bernard of Chartres's authorship of the "Aeneid" commentary to a number of similarities and differences between this work and other texts. What needs to be asked here though is why is Vernet still turned to for answers on Silvestris, when he wrote on the subject in 1938? It seems as though we do not have a choice, because even more modern writers, such as Jones, continue to cite him because there is no one else to look to. Vernet still has authority on the subject matter.
