Aristophanes of Byzantium
Aristophanes of Byzantium was a Hellenistic Greek scholar, critic and grammarian, particularly renowned for his work in Homeric scholarship, but also for work on other classical authors such as Pindar and Hesiod. He soon moved to Alexandria and studied under Zenodotus, Callimachus, and Dionysius Iambus. He succeeded Eratosthenes as head librarian of the Library of Alexandria at the age of sixty. His students included Callistratus, Aristarchus of Samothrace, and perhaps Agallis. He was succeeded by Apollonius "The Classifier". Aristophanes' pupil, Aristarchus of Samothrace, would be the sixth head librarian at the Library of Alexandria.

Accent system
Aristophanes is credited with reducing the accents used in Greek to designate pronunciation to a definite accent system, as the tonal, pitched system of archaic and [Ancient Greek (language)|Greek language|Classical Greek] was giving way to the stress-based system of Koine. This was also a period when Greek, in the wake of Alexander's conquests, was beginning to act as a lingua franca for the Eastern Mediterranean. The accents were designed to assist in the pronunciation of Greek in older literary works.Punctuation
He also invented one of the first forms of punctuation in BC: single dots that separated verses, and indicated the amount of breath needed to complete each fragment of text when reading aloud. For a short passage, a stigmḕ mésē dot was placed mid-level. This is the origin of the modern comma punctuation mark, and its name. For a longer passage, a hypostigmḗ dot was placed level with the bottom of the text, similar to a modern colon or semicolon, and for very long pauses, a stigmḕ teleía point near the top of the line of text. Heused a symbol resembling a for an obelus.
