Note 35 — Chapter XXXVI
Reading edition
The numerous MSS vary so in text and arrangement that it is not clear whether Adelard’s work in its original form “was an abridgement, a close translation, or a commentary,” (Haskins (1911) 494-5).
Professor David Eugene Smith states in his forthcoming edition of Roger Bacon’s Communia Mathematicae, which he has very kindly permitted me to see in manuscript, that Roger refers several times to Adelard’s Editio specialis super Elementa Euclidis—“a work now entirely unknown.”
