 The most ancient glossarist of the Decretals of Gregory IX is Vincent of Spain; then follow Godefridus de Trano (died 1245), Bonaguida Aretinus (thirteenth century) and Bernard of Botone or Parmensis (died 1263), the author of the "Glossa ordinaria", i.e., of that gloss to which authoritative credence was generally given.At a later date some extracts were added to the "Glossa ordinaria" from the "Novella sive commentarius in decretales epistolas Gregorii IX" by Giovanni d'Andrea (Johannes Andreæ).After the invention of printing, the Decretals of Gregory IX were first published at Strasburg from the press of Heinrich Eggesteyn.
