Menander in Harpers Dictionary of Classical Antiquities (1898)
A Greek rhetorician of Laodicea, who probably lived at the end of the third century after Christ. He is the author of two treatises about speeches for display, which add to our knowledge of the theory of the sophistic type of oratory. They can be found in Spengel's Rhetores Graeci, iii. 331- 446.
Menander Rhetor in Wikipedia
Menander of Laodicea on the Lycus was a Greek rhetorician and commentator.
Two incomplete treatises on epideictic (or show) speeches have been preserved under his name, but it is generally considered that they cannot be by the same author. Bursian attributes the first to Menander, whom he placed in the 4th century, and the second to an anonymous rhetorician of Alexandria Troas, who possibly lived in the time of Diocletian. Others, from the superscription of the Paris manuscript, assign the first to Genethlius of Petrae in Palestine.
In view of the general tradition of antiquity, that both treatises were the work of Menander, it is possible that the author of the second was not identical with the Menander mentioned by the Suda; since the name is of frequent occurrence in later Greek literature. The first treatise, entitled xyz, discusses the different kinds of epideictic speeches; the second, abc, has special titles for each chapter.
