Plagiarism This source which is from Medieval Italy an Encyclopedia ed Christopher Kleinhenz has been plagiarized or nearly so in a version of this article Take this old version of the article as a reference point and compare the following emphasis added by me Dionigi di Borgo San Sepolcro born circa 1300 died 1342 was from Sansepolcro near Arezzo Wikipedia Dionigi c 1300 1342 was born in Sansepolcro near Arezzo Medieval Italy He was an Augustinian scholar of very keen intellect and was much sympathetic towards others Wikipedia He entered the Augustinian order at a young age and immediately distinguished himself by his keen intellect and piety Medieval Italy Dionigi was a scholar trained as an astrologer in Sorbonne as well as a theologian He received his doctorate circa 1324 Wikipedia He studied theology at the Sorbonne in Paris and received his doctorate c 1324 Medieval Italy One of Dionigi s works which since has been lost is his commentary circa 1339 1342 on Valerius Maximus s Factorum et dictorum memorabilium libri Wikipedia Almost all of Dionigi s own writing has been lost His most famous work is his commentary probably c 1339 1342 on Valerius Maximus s Factorum et dictorum memorabilium libri Medieval Italy It became a template for subsequent commentaries on Valerius Maximus and also for several of Boccaccio s reference works such as Esposizioni and Genealogia deorum gentilium Wikipedia This commentary with its many citations of classical authors became a template not only for subsequent commentaries on Valerius Maximus but also for several of Boccaccio s nonfictional works such as Esposizioni and Genealogia deorum gentilium Medieval Italy Another of Dionigi s writings is a commentary on the first book of the Sententiae a treatise on logic and still another is a commentary on the pseudo Aristotelian Oeconomia Wikipedia Dionigi s other writings include a commentary on the first book of the Sententiae a treatise on logic and a commentary on the pseudo Aristotelian Oeconomia Medieval Italy And that s just the first two paragraphs of that version of the WP article In my opinion this is a clear cut case of plagiarism and a violation of copyright Some of this remains in the article some has been altered but there s obviously a larger concern of whether there are other instances of plagiarism in the article I m not sure how to proceed
