John Wycliffe's 19 reformation articles on church-related items as he wrote in his On Civil Dominion [5] and 21 proposed reformation articles of Johannes Klenkok's Decadicon [6] that he wrote against the Sachsenspiegel law-book. The Decadicon was submitted to Pope Gregory XI in the early part of the 1370s by French canonist and cardinal of the Curia Pierre de la Vergne. Gregory formally condemned fourteen articles of the Sachsenspiegel in 1374 [7] and nineteen propositions of Wycliffe's On Civil Dominion in 1377.[5]
