Bedeutung:"The earliest surviving "estern Physics Commentary" [Wood (1994), 87].

Authentizität:

S. Donati hält den Text ebenfalls für früh, die AUtorschaft des Richardus Rufus aber nicht für erwiesen. 

Zuschreibung und Datierung des Kommentars sind noch kontrovers, aber Wood (2003), p. 74: "If the Physics commentary should prove to be by an author other than Richard Rufus, that would be an amazing coincidence ... [A] coincidence of the sort that would account for two Richards active in the 1230's, holding the same views, is not the sort of possibility we should expect to have to exclude in establishing medieval atributions; to require that would exceed the degree of certainty appropriate to the discipline. Rather, until there is reason to belive that such a second author exists, we can confidently ascribe this work to Richard Rufus of Cornwall."
