One of the canonical Athenian orators, Lysias was much admired in antiquity. This new critical edition seeks to make the whole surviving corpus of Lysias available to the modern reader. It combines a newly edited text of the speeches preserved in the medieval manuscript tradition (based on the most up-to-date evaluation of the transmission) with a comprehensive collection of the fragments preserved indirectly through citation in ancient sources and in papyrusdiscoveries in the twentieth century. A general introduction in English provides an overview of the transmission of the text in antiquity and the Renaissance. An appendix contains a number of speeches almost certainly not written by Lysias but occasionally attributed to him in modern times.
