  Thomas of Erfurt's De modis significandi has enjoyed more attention than it might otherwise have received thanks to its early misidentification as a work of Duns  Scotus.[18]  As a result, it was printed along with authentic works on logic in volume 1 of Luke Wadding's seventeenth-century edition of the Opera Omnia of Duns Scotus (Lyons 1639), and again in the nineteenth-century reprint of Wadding by Juan-Luis Vivès (Paris  1891).[19]  Until recently, the Wadding-Vivès edition was the definitive source for the works of Scotus, so anyone consulting it would have associated De modis significandi with  him.[20] Complicating the story somewhat is the fact that Scotus was influenced by Modism early in his career, though this was probably due to his exposure to Modist authors such as Simon of Faversham and Andrew of Cornwall.[21]  It is unlikely that he was influenced by Thomas of Erfurt, because De modis significandi did not circulate widely until after Scotus's death.
