Le lettere di Martino Corbo «Ambrosiani saporis amicus»

The correspondence between the canons of Regensburg Paul and Geberhard and Martinus Corbo, chief of St. Ambrose canons around 1130-1154, deals with philological questions in collecting the whole works of St. Ambrose and political troubles in Milan during the papal schism of 1130. This article provides critical edition and full historical commentary of five letters that Martinus ordered to be copied in the last folios of his manuscript of Ambrose’s letters, now lost. This book can be reconstructed from two direct copies made in the XIV and XV century (Vat. lat. 281 and Ambr. F 114 sup.)
