Intense scrutiny can raise chimaeras, and Virgil is the most scrutinized of Roman poets, but he may have engineered coincidences in line number (‘stichometric allusions’) between certain of his verses and their Greek models. A handful of potential examples have now accumulated. Scholars have detected Virgilian citations of Homer, Callimachus and Aratus in this manner,Footnote 1 as well as intratextual allusions by both Virgil and Ovid,Footnote 2 and references to Virgil's works by later Roman poets using the same technique.Footnote 3 (For present purposes I disregard the separate, though related, phenomenon of corresponding numbers of lines in parallel passages: G. Knauer, Die Aeneis und Homer (Göttingen, 1964) suggests several examples of such correspondences between Homer and Virgil, especially in speeches. Another purely formal mode of allusion faintly present in Roman poetry is homophonic translation (the technique which Louis Zukofsky's 1969 translations of Catullus pursue in extenso); thus Virgil's fagus, beech, corresponds with Theocritus' phagos, oak.)Footnote 4 If genuine, the phenomenon lacks any consistent method or regular pattern (and the degree of plausibility varies); if genuine, it is very rare, even if accidents in textual transmission could have obscured some examples;Footnote 5 if genuine, it probably originated in the Hellenistic period,Footnote 6 although such a case has yet to be made. Virgil presently seems the earliest and most copious practitioner of stichometric allusion. A previously undetected example in the Aeneid is proposed below.Footnote 7
When Dido vows to return after death to avenge herself on Aeneas (Aen. 4.384–6), she echoes Apollonius' Medea, who threatens Jason that she will return from Hades as an Erinys (Argon. 4.383–7). This is one of many parallels observed between Apollonius' Medea and Virgil's Dido.Footnote 8 Although the concept of the dead seeking personal revenge is very old,Footnote 9 as is that of Erinyes/Furies avenging crimes by pursuing divine justice, Hellenistic heroines were apparently the first to link heartbreak with punishment by the Furies. The inspiration may have been the threat of Medea's sister Chalciope, in which familial bloodshed has an indirect role. She warns that, if betrayed by Medea, she will be murdered by Aeetes and return as an Erinys to haunt her.Footnote 10 Later heroines present personal betrayal itself as the pollution of a family bond, tantamount to indirect murder, and punishable by the vengeful spirits of the tragic stage. Thus Catullus' Ariadne invokes the Eumenides to punish Theseus (64.192–7), who, according to pre-Hellenistic sources, would not fall under their jurisdiction.Footnote 11 Medea and Dido each repeat Chalciope's extraordinary claim that they will turn into an Erinys figure after death to hound and punish their faithless lovers. This blending of two roles – the Erinys and the vengeful revenant – tightly links Dido to Medea, because both are necromancers who deal with Hecate, besides being abandoned heroines.Footnote 12
The formal parallel occurs in Dido's curse-promise, ‘I shall be present as a shade wherever you go: you shall pay the penalty’, which is expressed similarly to Medea's curse ‘may my Erinyes persecute you’. The book and line numbers correspond: 4.386 and 4.386.Footnote 13 I am grateful to Donncha O'Rourke for observing that shadows (umbrae) potentially signify ‘ghosts’ of prior texts, or alternatively the poet's lasting fame.Footnote 14
The number connecting Virgil with Apollonius, 386, does not seem visually or mathematically significant; all the more reason to believe that Virgil observed line numbering minutely, either as a compositional technique, or with some expectation that his readers might notice them too.Footnote 15
