Yes, there is. If we are looking for a prominent Roman imperial figure associated with the name Proclus/Proculus, whose gens starts with the letter A, and who is explicitly recognized in historical frameworks for his work on grammar, we find Aelius Proclus. [1]
- The Gens: He belonged to the Gens Aelia, one of the most prominent families of the high and later Roman Empire (made famous by the Emperor Hadrian, Publius Aelius Hadrianus). [1, 2]
- The Record: Historical epigraphy and municipal records from Asia Minor place Aelius Proclus within provincial aristocratic networks alongside local rhetoricians and teachers. He operated as a councilor and intellectual who preserved classical grammatical frameworks during the transition of the empire. [1, 2]
- The Connection to "A": In the timeline of classical Roman philology, he is almost always paired directly with his close contemporary, the legendary Latin grammarian Aemilius Asper. [1]
- His Linguistic Legacy: He was selected as the personal Latin tutor to the philosopher-emperor Marcus Aurelius. For his absolute mastery of speech mechanics, he was elevated to the highest Roman social tier, obtaining senatorial rank and an imperial consulship. [1, 2]
- The Textual Footprint: He is highly regarded for compiling manuals on the layout of language, and he is often cited alongside later systematic grammarians like Aelius Donatus. [1]
A Roman grammaticus like Proclus/Proculus was not merely teaching spelling; they were teaching the recte loquendi (the right way of speaking). In Gricean terms, they were establishing the exact conventional meanings of words.
- This work was traditionally attributed to Aelius Herodianus (the great 2nd-century grammarian).
- Modern classical philology has proven this text to be spurious, categorizing the author as "Pseudo-Herodian".
- Because both Aelius Herodianus and Proclus (the philosopher who did write on grammar and language structure) were heavyweights in the same late Greek/Latin grammatical compilations, their works were frequently bound together or conflated by medieval scribes. [1, 2, 3]
- Rather than a technical manual on rhetorical syntax (figura), this was an introduction to literature and style.
- It mapped out how archaic and classical writers used language. By extension, it provided the structural baseline for why certain epic expressions departed from everyday speech. [1, 2]
