For centuries, epideictic
oratory was a contested term, for it is clearly present in both forensic and deliberative forms, but it is difficult to clarify when it appears as a dominant discursive form. According to
Chaïm Perelman and Lucy Olbrechts-Tyteca, “The speaker engaged in epidictic discourse is very close to being an
educator. Since what he is going to say does not arouse
controversy, since no immediate practical interest is ever involved, and there is no question of attacking or defending, but simply of promoting values that are shared in the community . . .” (52). Some of the defining terms for epideictic discourse include declamation, demonstration, praise or blame of the personal, and pleasing or inspiring to an audience. Lawrence W. Rosenfield contends that epideictic practice surpasses mere praise and blame, and it is more than a showy display of rhetorical skill: “Epideictic’s understanding calls upon us to join with our community in giving thought to what we witness, and such thoughtful beholding in commemoration constitutes memorializing”. Epideictic rhetoric also calls for witnessing events, acknowledging temporality and contingency (140). However, as Rosenfield suspects, it is an uncommon form of
discourse because of the rarity of “its necessary constituents — openness of mind, felt reverence for reality, enthusiasm for life, the ability to congeal significant experiences in memorable language . . .” (150). The philologist
Ernst Curtius provides an account of its history, and many examples, in
European Literature and the Latin Middle Ages. Praise and blame were "reduced" to praise by Aristotle, he wrote; and recently another author called it a "blameless genre". He and Lockwood seem to say that what was in the past called rhetoric was later called literature. Curtius believed that misinterpretations of
medieval literature occur because so much of it is epideictic, and the epideictic is so alien to us today. During the Middle Ages it became a "school subject" as the sites for political activity diminished in the West, and as the centuries went on the word "praise" came to mean that which was written. During this period literature (more specifically histories, biographies, autobiographies, geographies) was called praise.
Ben Witherington III, writing from a biblical perspective on sacred exhortation, noted that "in general, epideictic rhetoric is highly emotional and meant to inspire the audience to appreciate something or someone, or at the other end of the spectrum, despise something or someone. Epideictic rhetoric seeks to charm, or to cast odium."
Commendatory verse is a genre of epideictic writing. In the Renaissance and Early Modern European tradition, it glorified both its author and the person to whom it was addressed. Prefatory verses of this kind— e.g. those printed as
preface to a book—became a recognised type of advertising in the book trade. ==In poetry==
