67 Cic, . Div. 1.36, 2.62Google Scholar, citing a letter written by C. Gracchus to M. Pomponius; Val. Max. 4.6.1; Plin. NH (offering the only surviving Latin version of Gracchus' utterance: immo vero, inquit, meum necasse, Cornelia enim iuvenis est et parere adhuc potest); Plut, . TG 1.2–3Google Scholar; de vir. ill. 57.4. Note, in passing, the emphasis in this context on Cornelia's child-bearing. Cicero's source (Gaius' friend Pomponius) obviously suggests that the incident was susceptible to a reading friendly to the Gracchan household. It is also clear that the surviving tradition (concentrating, as it does, on the elder Gracchus’ selflessness) is heir to that friendly interpretation. On the other hand, it seems a safe presumption that enemies of the Gracchi would have focussed not upon the heroic self-sacrifice of Gracchus but upon the inescapable severity of the divination. It is noteworthy that this tradition did not prevail - but that need not detract from the logic of a hostile interpretation of the omen.
Köves-Zularf, Th., Reden und Schweigen. Römische Religion bei Plinius Maior (Munich 1972) 273-4Google Scholar, ingeniously points to the relevance in this regard of the dire omen which preceded the death of Gracchus the Elder; cf. Burckhardt and von Ungern-Sternberg, ‘Cornelia’ (n. 7) 103-5. The haruspices, summoned to interpret the sign, announced that one of the serpents must be killed and that the sex of that reptile would correspond to the imminent death of either Gracchus or Cornelia, upon which Gracchus ordered that the male snake be killed on the grounds that his wife was young and might still bear children. At Div. 2.62, Cicero professes a certain degree of bafflement; why not let both snakes go free? Plutarch answers that question: the soothsayers had ordained that one snake was to be killed. The haruspical response is startling; the two reptiles most aptly, one would think, signify the genius of Gracchus and the iuno of Cornelia (cf. Corradi, , Cornelia e Sempronia [n. 19] 14Google Scholar; Burckhardt, and Ungern-Sternberg, von, ‘Cornelia’ [n. 7] 105, esp. n. 30)Google Scholar and therefore marital union. Köves-Zularf, loc. cit. 273 n. 515, highlights the fact that the haruspices’ finding presupposes the end of the married couple's coexistence, and that the marriage was not meant to be, not sanctioned, and must be ended (‘daß die Ehe des Sempronius Gracchus mit Cornelia gar nicht als richtige Ehe galt und deswegen nicht geschützt, sondern vernichtet werden sollte’). For a discussion of the practicalities of the haruspical response, see Köves-Zularf, loc. cit. 270-8 (cf. 283, 287-8 n. 556); he cogently, in our opinion, links this to Cornelia's birth-omen (n. 515; for his earlier discussion of which, see 222-4) – though Burckhardt and von Ungern-Sternberg, loc. cit. 105 n. 31, remain wary.
