Perceptions of eastern frontier policy in Ammianus, Libanius, and Julian (337–363)*
Published online by Cambridge University Press: 11 February 2009
Extract
It is the purpose of this paper to examine how Ammianus, Libanius, and Julian conceived of Roman policy on the eastern frontier from the death of Constantine to failure of Julian′s invasion of Persia. Any consideration of the actual facts is secondary. The predominant conclusion will be that all three saw Rome′s as essentially defensive, her objective as the containment of persistent aggression. This will be seen to hold good even for Julian′s invasion., when they are offered by the sources, are presented in terms of, whether national or that of individuals: Constantius, Julian, Jovian, and. It will become apparent, and is sometimes implied, that these attitudes derive the peace imposed by Rome in 299, with which Rome could well rest content, Persia clearly could not.

Kennedy, The Defence of the Roman and Byzantine Eastii (Oxford, 1986), p. 459 (conceding that Sapor might have attacked anyway); contra: Barcelo (n. 1), pp. 90f.
9 The use of turbarehere, with its connotations of interference with what is right and proper, is extremely appropriate to the Roman point of view. Cf. Seager, R., Ammianus Marcellinus, Seven Studies in his Language and Thought(Columbia, 1986), pp. 92ff.Google Scholar
10 Warmington (n.2), p. 515, believes that the objective of the Blitzkriegwas merely to force Constantius to battle. Blockley, Phoenix42 (1988), 244, assumes that, even if Sapor had intended to invade Syria (which he denies; cf. next note), the object would have been merely plunder, not conquest.Google Scholar
11 Blockley, Phoenix42 (1988), 251f, argues (rejecting the story of the Euphrates flood) that Sapor never intended to invade Syria but was aiming at Amida from the first (thus also briefly ERFP,p. 22), though in Deroux (n. 2), pp. 483ff., he appears to accept Sapor′s change of plan as genuine.Google Scholar
12 For the message, cf. Blockley, Phoenix42 (1988), 256; in Deroux (n. 2), p. 484. As remarked by J. F. Matthews in Freeman and Kennedy (n. 8), p. 558, the message gave no details of the planned invasion route. 13 Blockley, Phoenix42 (1988), 256fT., seems to neglect this factor.Google Scholar

15 Cf. P. De Jonge on 19.1.6. The suggestion that Sapor was forced to besiege Amida to appease his allies (Matthews (n. 12), p. 557; The Roman Empire of Ammianus[London, 1989], p. 58) may underestimate the king′s own fit of pique.Google Scholar

26 The idea that Julian intended to conquer Persia is widely dismissed, usually on the inadequate ground that such a goal was unrealistic. Thus e.g. P. Petit in R. Braun and J. Richer, L′empereur Mien. De I′histoire a la legends(Paris, 1978), p. 80; Barcelo (n. 1), pp. 98f.; Blockley in Deroux (n. 2), p. 468; Matthews (n. 15), p. 139. But cf. Wirth (n. 3), pp. 460fF., 483ff.; A. Marcone, Athen.57 (1979), 343ff.; F. Paschoud, REL58 (1980), 122. On the Alexander motif and its possible value as a disguise for the fact that Julian was to some extent reviving the policies of Constantine, cf. Marcone, 342f.; W. E. Kaegi Jr, Athen.59 (1981), 209ff.; Barceld (n. 1), p. 100; and especially Blockley, ERFP,p. 25. That Julian′s admiration for Alexander was not unqualified is rightly stressed by R. Scholl, Historische Beitrdge zu den julianischen Reden des Libanios(Stuttgart, 1994), p. 138.Google Scholar

28 Stressed e.g. by Barcelo (n. 1), pp. 98f, but cf. Wirth (n. 3), p. 483.
29 On the conflict between haruspicesand ‘philosophers’, cf. Conduche (n. 27), 368ff.; Rike (n. 27), p. 63; Scholl (n. 26), p. 141.Google Scholar
30 Cf. Marcone (n. 26), 334ff. The parallel between what Julian is made to say here by; Ammianus and his own words at Or.2.86B is striking.
31 The embassy at least is probably historical. Cf. Barcelo (n. 1), p. 99; Blockley, Florilegium6 (1984), 34.
32 Scholl (n. 26), pp. 134fF. argues that the consular oration reveals veiled disapproval of the planned expedition and indirectly attempts to put pressure on Julian to negotiate. This seems to me inconsistent with the second half of Or.12.74.
33 Cf. Hor. C. 1.2.45ff.
34 Cf. above, n. 26.
35 For various estimates of the situation, cf. Turcan, R., Melanges Piganiol II(Paris, 1966), pp. 876ff. (exaggeratedly positive); N. Austin, J.E., Athen.50 (1972), 301ff.; Ridley, R.T., Historia22 (1973), 326 (also extremely positive); Wirth (n.. 3), pp. 461ff. (violently negative); Paschoud, Zosime, Histoire Nouvelle III(Paris, 1979), pp. xixff. (cogently negative, and with an excellent appreciation of Sapor′s strategy); Barcelo (n. 1), pp. 97, lOlf. (negative, and again with a just valuation of the quality of the Persian defence and its similarity to the strategy of Constantius); Matthews (n. 15), pp. 158f.; Scholl (n. 26), p. 139.Google Scholar
36 On the terms of the treaty, cf. Blockley, Florilegium6 (1984), 35ff.; ERFP,pp. 27ff. His earlier view (art. cit. 35 with n. 44) that Rome had not recovered Singara since 360 seems preferable.
