According to Schmeidler (1917), Adam created three versions of the text, in the convention of Schmeidler (1917) labelled • (A) representing his preliminary text, • (a) the work as given to bishop Liemar, and • (X) which he kept for his own use and supplemented with various additions (
scholia). None of the three archetypes has been preserved. The most relevant surviving manuscripts are classified into three groups, labelled A, B and C. The best manuscript is of group A, labelled A1 (
National Library Vienna, cod. 521), dated to the first half of the 13th century. Parts of book 2, book 4 and some scholia are also preserved in a ms. dated (
Leiden University Library, Codex Vossianus Latinus, VLQ 123). Manuscripts in the B and C groups are derived from version X. They contain independent additions of scholia. The best ms. in group B was the so-called Codex z, written 1161/2, which was however lost in the
Copenhagen Fire of 1728. Some copies of this ms. are extant. The best ms. in group C, labelled C1, is at the
Copenhagen Royal Library, Old Royal Collection, No. 2296 quarto (dated c. 1230). ==Editions==
