Two firm points in the chronology of Antiphon's speeches are VI περ το χορευτο in 419/81 and the Defence in 411/02. Speech V περ τσ 'Hρδου is now generally dated between these two; only the vaguest attempts have been made to date I κατ τσ μητρυασ; there is no general agreement on either the date or the authorship of the Tetralogies. The main purpose of this paper is to adduce linguistic as well as external evidence for the dating of V (...) in the neighbourhood of 414 and to show grounds for dating I between VI and V. Its secondary purpose is to apply some of the results gained in this inquiry to the fragments and the Tetralogies. (shrink)
