In his commentary on Aristotle's Physics, Nicole Oresme (c. 1320-1382) propounds a very specific theory of the ontological status of accidents. Characteristic of Oresme's view on accidents is that he does not consider them accidental forms, but only so-called condiciones or modi of the substance. Unlike the term ``modus{''}, the term ``condicio{''} seems to be very characteristic of Oresme's own terminology. Up to now it has been unknown whether Oresme exerted any influence with his condicio-theory of accidents. This paper presents an anonymous 14th-century commentary on Aristotle's Meteorology (Munich, Bayerische Staatsbibliothek, Clm 4375, ff. 19r-46v), in two Questions of which the term ``condicio{''} occurs in an ontological context. Moreover, the text shows further striking coincidences with known works by Oresme, and this makes an influence by Oresme appear all the more probable.
