A short work is attributed to the famous grammarian Remmius Palaemon (1st century CE, especially well known through Suentonius’ biography), although it contains a series of rules on inflection and grammatical quaestiones that do not show any relation to what the sources tell us about this grammarian’s works. The attribution is attested from the Humanist period (in fact, in addition to manuscripts of the 15th century, it is also present in the Oxford manuscript, Bodl. Lib., Add. C 144, from the second half of the 11th century, although it was added here as a note, by a humanist hand); it does not hold currency among modern editors. But it was accepted enthusiastically by the ‘discoverer’ of the text, the humanist Giovanni Pontano, who broadcast the news of his discovery, which probably occurred in Naples, around 1460. The work belongs to the ‘regulae type’, a distinct kind of grammar, complementary to the typology of the ars grammatica, of which the tradition considers Remmius Palaemon to have been the initiator. The text is very simple, but it was probably originally conceived for a Latin-speaking public —it contains few Greek technical terms — and in any case it is characterised by certain features of late Latin. All of this probably means that it originated in the West and in the early period of the regulae genre (beginning of the 4th century), before the composition of the Regulae Augustini, a text that is similar but already more detailed, and which derives in part from the same source.
