In an edited book, individual authors each contribute a chapter. The final publication is overseen by the editor(s), and their name(s) will be on the front cover of the book.
When you cite one of the chapters in an edited book in your text, you must cite the author(s) of that chapter, not the editor of the book. For the entry in your reference list, follow the guidance below, which you will also find in your Harvard guide. Make sure you include the page range of the chapter you are citing.

In the list of references, record the publication you actually sourced.
(Fong, cited in Bertram 1997)

Reprinted ancient Greek/Roman texts and classical religious works.
Reprinted chapter/article/section in a book of readings
