Asporius
Asporius
(fl. c.600?)
Asporius, known also as Asperius or Asper Minor (distinguishing him from Aemilius Asper), is the author to whom a grammar based on Donatus’ Ars minor is attributed. The possibility has been considered that he was an Irish or otherwise Insular grammarian and according to Vivien Law, he was probably active in Ireland or Burgundy.
