Littera Bononiensis, closely parallel to the Littera Florentina, would be disseminated throughout Europe as students returned home from Bologna: there are versions of the Bolognese Littera with provenances in Paris, Padua, Leipzig and at the Vatican (Purpura 2001). Works According to ancient opinion (which, however, has been much controverted), Irnerius was the author of the epitome of the Novellae of Justinian, called the Authentica, arranged according to the titles of the Code. His Formularium tabellionum (a directory for notaries) and Quaestiones (a book of judicial decisions) are no longer extant. The Summa Codicis, attributed to Irnerius by Herman Fitting in his 1894 edition is now widely considered a later work of between 1130 and 1159, but remains the earliest known summa on Justinian's Code <ref>Lange, Rómisches Recht im Mittelalter I (Munich, 1997), pp. 403-405.</ref> Another important work, Quaestiones de juris subtilitatibus, was generally ascribed to Irnerius until Hermann Kantorowicz published a manuscript from the British Museum. Other juridical works and glosses that are ascribed to Irnerius are extant only in fragments, or their authorship is uncertain. Reputation Irnerius was largely forgotten until his name was revived by German historians of the later 19th century and came to prominence with the celebrations marking the octocentennial of the University of Bologna. His name is also seen in manuscripts as Hirnerius, Hyrnerius, Iernerius, Gernerius, Garnerius, Guarnerius, Warnerius, Wernerius, Yrnerius. He called himself Wernerius when he signed documents. Anders Winroth has questioned much of the received account of Irnerius' life as well as his importance to the history of Roman law in the Middle Ages.
