Notes and references for classical Greek and Latin works can look a little different than many readers and writers are used to. The citation will often just have the name of the author, or the author and the title. Instead of a traditional page number, the book, section, or line may be used so that readers looking at different editions can still find the reference. See the Chicago Manual of Style Rules 14.242-14.247.
Examples:
1. Ovid, Amores 1.7.27.
2. Aristotle, Metaphysics 3.2.996b5–8; Plato, Republic 360e–361b.
3. Thucydides 8.44.4.
To reference a specific translation:
1. Epictetus, Dissertationes, ed. Heinrich Schenkl (Stuttgart: Teubner, 1916).
2. Herodotus, The History, trans. David Grene (Chicago: University of Chicago Press, 1987).
