Ammonius Grammaticus

Ammonius Grammaticus is the supposed author of a treatise titled Peri homoíōn kai diaphórōn léxeōn (περὶ ὁμοίων καὶ διαφόρων λέξεων, On the Differences of Synonymous Expressions), of whom nothing is known. He was formerly identified with an Egyptian priest who, after the destruction of the pagan temple at Alexandria (389), fled to Constantinople, where he became the tutor of the ecclesiastical historian Socrates.
