Lupercus of Berytus

Lupercus of Berytus (Greek Λούπερκος Βηρύτιος) was a Greek grammarian active during the 3rd century CE, likely flourishing shortly before the brief reign of Emperor Claudius Gothicus (268–270 CE). He was associated with the scholarly milieu of Berytus (modern-day Beirut), a prominent center of Roman and Hellenistic learning.​

Lupercus authored several works, including On the Word (Περὶ Λόγου), The Foundation of Arsinoe in Egypt, and other treatises. His writings contributed to the grammatical and rhetorical literature of his time and were occasionally cited by later scholars. Although much of his work has not survived, references to his contributions are found in historical sources.
