The brief text printed by Keil (GL 5.547-54) under the heading Aspri grammatici ars (a slight variation on the incipit in one of the two manuscripts he cited) certainly has nothing to do with the second-century grammarian Aemilius Asper (as the heading in Keil’s second manuscript claims). It is a very spare version of an ars grammatica that briefly defines the concept of ars, then the littera, syllaba, and pedes (so the second, third, and fourth sections of Donatus’ Ars maior, omitting the first, vox) before taking up the partes orationis in the order set by Donatus (nomen, pronomen, verbum, adverbium, participium, coniunctio, praeposition, interiectio). Beyond the fact that it was evidently dependent on and later than Donatus, nothing more can be said about the milieu in which it was written. [R. Kaster]
