 It represents the first effort at a coherent "Continuation of Saxo", as presented with more lasting influence (and in print) by Arild Hvidtfeldt in 1600.The "Colectanea" were extensively used by other historians already during Petrus' lifetime, notably by Paulus Helie for his "Skiby-chronicle", by Hans Svaning and by Anders Sørensen Vedel who inherited the "Colectanea" ms. after Petrus' death.Arne Magnusson acquired the ms. in 1726 and partial editions of the texts were published in "Scriptores rerum Danicarum" by Jakob Langebek beginning in 1772.
