“We don't want to be Americans, we don't want to be Danish, we want to be Greenlanders.”

#BookHistory Help needed! I have trouble identifying this incunable page (back pastedown in a 1491 Cologne legal treatise, ISTC is00496000). Starting at "Non solum" seems to be a paraphrase and commentary on Decret., Lib. II, Tit. XV, cap. VII. Early provenance: Italy, c.1500.
