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.

Anonymous grammarian, probably of Irish origin, who worked on the continent and produced a grammatical treatise structured as a series of questions and answers, with ample citations from standard grammars such as Donatus and Priscian. The title Donatus ortigraphus is also applied as a shorthand for the work itself.

Letter from Suadbar, one of four Irish scholars on the continent (the others being Caínchobrach, Fergus and Dominnach), to their teacher Colgu. It relates that when the group had been received at the court of Merfyn Frych (king of Gwynedd, r. 825-844), a cryptic message was left for them by an Irish scholar called Dubthach. To put the wisdom of the Irishmen to the test, it contained a cryptogram, the key to which involved substituting Greek numerals for Roman letters. Once deciphered, the message would read Mermin rex Conchn [sic] salutem (‘Merfyn the king greets Cyngen’, i.e. Cyngen ap Cadell, king of Powys). In a final note, an error in the form of Cyngen’s name (Conch(e)n, betraying Irish influence, for Concen) is pointed out.
