- 2003, “The Preliminary Exercises of Aphthonius the Sophist”, in George Alexander Kennedy, editor, Progymnasmata: Greek Textbooks of Prose Composition and Rhetoric‎^[1], Brill, Leiden, The Netherlands, Footnote 79, page 115.:
  The status of the speaker at the time the speech is imagined as being given is what determines whether it is ethopoeia or eidolopoeia. A speech Heracles might have given while alive is an example of ethopoeia, a speech he might have given after death is an eidolopoeia
