When Mommsen saw foll. 28r line i–29r line 6 of cod. Paris, Bibl. Nat. lat. 7530, an eighth-century grammatical miscellany from Monte Cassino, he realised immediately the importance of their contents. He wrote to Bergk about his discovery on 2 November 1844 and Bergk published the material early the next year as being an epitome of a treatise on signs applied to literary texts by Probus and earlier Latin grammarians. There had long been known Diogenes Laertius' account of the χ (...) and other signs placed in the margins of texts of Plato's dialogues, Hephaestion's account of the colometrical παράγραος, κορωνίς, διπλ and στερίσκος placed in texts of lyric and dramatic poetry, the chapter de notis sententiarum in Isidore's Origines, the names of various treatises περσημείων mentioned in the Suda, the references to σημεα in Eustathius' commentary on Homer' and in the marginal scholia to Homer, Hesiod, Pindar, Aeschylus, Sophocles, Euripides and Aristophanes in Byzantine manuscripts, Cicero's allusions to the βελός and the διπλ scattered reports of the signs with which Origen equipped Greek versions of the Old Testament and Jerome's adaptation of Origen's system, and Cassiodorus' account of his own method of noting orthodox and heterodox opinions in ecclesiastical writings.
