Extant in some eight manuscripts. The likely original is the Berlin ms. (Geheimes Staatsarchiv Preußischer Kulturbesitz, VIII. HA II, Nr. 21), dated 9 April 1483 in the preface but presumably completed in 1485/86. Others include Bayerische StaatsbibliothekCgm 145 and Cgm 9210.
Cgm 9210 is a copy dated 1602–1604 with numerous changes.
