Abstract: In the Rhétorique de l’éloge L. Pernot elucidates the purposes of ekphrasis in speeches of praise, identifying them in the evocation of pleasant sensations or strong emotions (pity or indignation). In both circumstances the contribution of vividness (ἐνάρ-γεια) is important. This paper draws inspiration from the words of L. Pernot to link ἔκφρασις and διατύπωσις, often wrongly considered synonymous, to different purposes of description and to explain the word-image relationship in the rhetoric of social media.
