The present work is concerned with presenting an investigation of the occurrence of Figures of Speech in Isaeus' speeches, and an analysis of their arrangement, in an effort to show how the factors of Figures and Arrangement are connected with the content of the speeches. This present study relies for its originality and value on the fact that it is essentially directed towards providing the reader with a general numerical survey of Isaeus' speeches, which has - up to now - been lacking in the corpus of works on Isaeus.
