About Lexeis

Welcome to the Lexeis page! The goal of this project is to produce modern author-specific lexica, so we use the term "Lexeis," following the practice of ancient authors of author-specific lexica (like Apollonius Sophista, Harpocration, and Erotian).

Our first project was the Thucydidean Lexicon; our current project is the Platonic Lexicon

For more on the Thucydidean Lexicon, view the lexicon's own about page.

For screencasts describing the features of each lexicon (as of January 2021) view Jeffrey Rusten's home page.

See the next steps page for more on the future of the project.
