Diodotus, Son of Eucrates Ostwald, Martin Greek, Roman and Byzantine Studies; Spring 1979; 20, 1; Periodicals Archive Online pg. 5 Diodotus, Son of Eucrates Martin Ostwald THE TITLE of this paper gives us one of the only two facts known about the man to whom Thucydides assigns one of the most profound and important speeches in his History. The other fact is that the speech reported by Thucydides was not Diodotus' first on Clean's motion in the summer of 427 B.C., that all adult male M ytileneans be killed and their women and children be taken as slaves: he had been the most vociferous opponent of that motion already a day earlier when it had been successfully passed by the Athenian Assembly.! To try to identify Diodotus by identifying his father is almost hopeless. Of the twenty-five men named Eucrates listed in the Prosopographia Attica, there are two possible candidates: one is the CTV7T7T€W7TWATJC mentioned in Aristophanes' Knights as a predecessor ofCleon as a demagogue 2 and the other was a general in 432/1 B.C.3 A third possible candidate is Nicias' brother Eucrates,4 but argu­ ments based on names alone cannot be very strong. Whether Diodotus was the son of any of these three can only be guessed, and even if we could guess accurately, it would tell us nothing significant about Diodotus, unless additional information on the various persons named Eucrates were also to come forth. The purpose of this paper is to seek a little more light on the iden­ tity of Diodotus from a much neglected passage in the much dis­ cussed speech which Thucydides puts into his mouth. In the course of his plea against Clean that a renewed deliberation of the Mytilenean issue is beneficial rather than harmful to Athens, Diodotus states: 1 For the motion, see Thuc. 3.36.2; for Cleon's sponsorship in the first Assembly meeting, ibid. 36.6; for his advocacy of it in the second meeting, ibid. 37-40. For Diodotus' opposi­ tion in the first Assembly meeting, see ibid. 41; in the second, ibid. 42-48. 2 Ar. Eq. 129 with schol.; if. ibid. 254 with schol. and fr.696 (K). 3 IG P 296.5 with C. W.

Those who have commented on the peculiarity of this passage at all have brought the ypac/>~ 1Tapav6p.wv into the discussion,6 but only rarely has the question been raised in what way Diodotus might envisage the possibility that his remarks could be construed as a violation against which this procedure, unattested before 415 B.C., could have been invoked.7 To the best of my knowledge, only G. Mathieu has something to say on that subject.8 He believes that Cleon might have invoked the ypac/>~ 1Tapav6p.wv against Diodotus' request for reopening an issue already voted upon by the Assembly, implying that the proposer of renewed discussion ofa decision already made was subject to this procedure. But the parallel he cites is no true parallel. When Nicias encourages the prytanis not to be afraid of putting the decision to sail against Sicily to a vote again, since "he could not be charged with subverting the laws, if so many witnesses are present,"9 he is speaking of formalities which have not been observed, whereas in the Mytilenean debate the necessary formalities had been observed and the permission to reopen the question had been granted by oi EV ,dA£t.10 Moreover, there is neither any indica­ tion that the request to reopen the debate had come from Diodotus nor any evidence that such a request made the proposer subject to Ii Thuc. 3.43.4: "Faced with matters of the greatest importance and in the kind of situation in which we are, we must be expected, as we make our speeches, to be thinking ahead rather further than you who give the issue but a moment's attention, especially as the advice we give is subject to an accounting, whereas the hearing you give is subject to no accounting." 6 E. F. Poppo, Thucydidis De Bello Peloponnesiaco II.I2 (Leipzig 1875) ad loc., seems to have been the first to assert: "poterant enim eis intendi ypacpal '1rapa.vop.wv." Cf, more recently C. F. Smith in the Loeb ed. of Thucydides, II (1920) 75: "It was open to any Athenian citizen to impeach any law or decree, as contrary to some existing law or as unjust or inexpedient, by a proceeding called ypacp-q '1rapavop.wv." 7 Even H. J. Wolff, in his magisterial" 'Normenkontrolle' und Gesetzesbegriff in der attischen Demokratie," SBHeidelb. 2. Abh. (1970) 15 with n.2Ia, does not argue his belief that a reference to the ypacpT] '1rapavop.wv here is possible but not provable. 6 G.
