Abstract
In the course of studying ancient Greek diplomatic relations I have come to think that one item of evidence deserves a little more said about it than it has, up to now, received. Tod 11.154, entitled Athens aids Eretria: 357–6 B.C.', is a document whose significance in Greek diplomatic history has not, I suggest, been fully appreciated. It is a unique epigraphic record of a genre of diplomatic instrument that was available to states which wished to emphasize their non-belligerence. R. Bauslaugh has recently gathered the literary evidence for the use by neutral states of this type of instrument, prohibiting a state's citizens from serving as mercenaries for a foreign power, but he did not consider this decree, in which a state uses the same instrument to demonstrate its goodwill towards its allies.
