Marcus Valerius Probus

[2] He was a student rather than a teacher, and devoted himself to the criticism and elucidation of the texts of classical authors (especially the most important Roman poets) by means of marginal notes or by signs, after the manner of the Alexandrine grammarians.

In this way, he treated Horace, Lucretius, Terence and Persius, the biography of the latter being probably taken from Probus's introduction to his edition of the poet.

Part of one of his treatises, De notis, has also been preserved (probably an excerpt from a larger work).

It contains a list of abbreviations used in official and historical writings (especially proper names), in laws, legal pleadings and edicts.
