Abstract
My purpose in this note is to examine the evidence for the witness's oath of disclaimer in the Athenian lawcourts. This is an issue on which modern discussions tend to be brief for want of ancient evidence. However, although our ignorance on matters of detail relating to the exomosia remains, and is likely to remain, profound, I believe that we can, by a careful reading of the limited evidence which is available, draw a number of more or less confident conclusions about the form and content of the oath and the degree of restriction it imposed on witness and litigant. The lexicographers have the following to say on pressures applied to recalcitrant witnesses: Polydeukes 8.37: τóν δ' ο βονλóμενον μαρτρεν κλτενον το μαρτνρεν πρρστιθντεσ δι δ ατóν μαρτνρεν ζομóσασθαι σ οκ εíδεíη μ χιλíασ ποστíνειν. κλητεσθαι μν ον στí καλεíσθαι εíσ μαρτνρíαν, κκλητεεεσθαι δ τó δíκην óφεíλειν πí τπí τι τσ χιλíασ καταβαλεíν
