Silva Rhetoricae is divided into two portions. On the left side, visitors can follow a wonderfully, clear and simple introduction to the key ideas in the art of rhetoric: kairos, logos, ethos, invention, memory, and many more. Many are accompanied by examples ancient, modern and contemporary. The right side catalogues the various techniques employed, such as hyperbole, parallelism, and synedoche. Terms are searchable by Greek, Latin and English names, or by similarity of type.
Typically Memory has to do only with the orator, but invites consideration of how the audience will retain things in mind. To this end, certain figures of speech are available to help the memory, including the use of vivid description (ecphrasis) and enumeration. Along with Delivery, Memory has often been excluded from rhetoric. However, it was a vital component in the training of orators in antiquity.
Orators were encouraged to envision where they would be speaking as a preparation for memorizing their speech. Then, having completed the speech's composition, they were to divide it into manageable portions, each of which they would assign, in turn, to a different part of the room where the speech was to occur. Thus, by casting their eyes about during their speech, they would be reminded of the next part of their speech to give.
