The fourth choral ode in Seneca's tragedy Troades ends thus (1050–5):
This ending provides a powerful conclusion to the Chorus’ Epicurean-inspired philosophizing in the ode.Footnote 2 The image of the Trojan women ‘seeing’ (uidebunt)Footnote 3 the ‘smoke and squalid clouds creep[ing] high into the heavens’ (1053–4) recalls the Lucretian description of the soul, atomic in nature, leaving the dead body: compare especially et nebula ac fumus quoniam discedit in auras, | crede animam quoque diffundi … (Lucr. 3.436–7) and ergo dissolui quoque conuenit omnem animai | naturam, ceu fumus, in altas aeris auras (Lucr. 3.455–6).Footnote 4 The image and the Lucretian resonance also create an intratextual link with the second ode of Troades (371–408). In that ode, the Chorus set out to develop a philosophical position about the question of death and the possibility of an afterlife. Their philosophizing is aided by Lucretian language and imagery,Footnote 5 and the clear verbal echoes of Lucretius include the soul escaping into air like vapour: ‘the spirit, with fleeing breath, has mingled with the clouds and passed away into air’ (… profugo spiritus halitu | immixtus nebulis cessit in aera, 379–80), which recalls the Lucretian lines above. At the end of the fourth ode, the Lucretian intertext of the smoke image is linked to another startling element that may point to (Epicurean) philosophizing: Seneca's use of signum (1055).
The meaning of signum here has not been fully understood. This is evident from Fantham's comments: she identifies this use of signum as ‘unconventional’, then cites four possible meanings,Footnote 6 ‘a sign sent by the gods […] or weather portent […] or a conventional signal or indicator established by men, the standard of the legion, the battle trumpet […]; it can also stand for physical or psychological symptoms’, before deciding that ‘here it must be a marker, pointing the way’.Footnote 7 But pinpointing the denotation of signum here as ‘marker’ may obfuscate one strong connotation of the word. While Fantham's reasoning for arriving at her preferred translation is perfectly acceptable and accords well with the spatial deixis of the lines (cf. monstrans, 1051; digito notabit, 1052; illic, 1053; and hoc signo, 1055), there is another explanation, not posited before, that accounts for Seneca's use of signum in the context of this Chorus.
An important resonance of signum at this point—in an ode, which, as I have noted, also otherwise engages with Lucretian-Epicurean elements—is as part of another of the Chorus’ attempts at philosophical reasoning. The Latin signum, I suggest, translates the Greek σημεῖον and carries with it the trace of its pervasive uses in philosophical debates about inference and the nature of evidence.Footnote 8 This discourse was a key issue of debate between Academics, Epicureans, Stoics and Sceptics.Footnote 9 The Epicureans were the only ones to hold on to an approach to signification that, essentially, relied on analogy,Footnote 10 a technique that, I shall suggest below, Seneca criticizes in this Chorus. Seneca, moreover, is also likely to have been aware of the proto-philosophical uses of the term σημεῖον in Greek tragedy.Footnote 11 At the end of the fourth Chorus in Troades, Seneca would thus restore the term from philosophical discourse to the tragic realm. That such a use of signum is significant in the context of our choral ode can be corroborated further: in Aeschylus’ Agamemnon, smoke is already given as the characteristic of the conquered city Troy (καπνῷ δ᾽ ἁλοῦσα νῦν ἔτ᾽ εὔσημος πόλις, 818),Footnote 12 and such usage may be echoed in Seneca's nota at Ag. 459, Iliacus atra fumus apparet nota.Footnote 13 In the Epicurean-tinged ode in Troades, Seneca describes the same situation not with nota but with signum. It is worthy of note that Cicero had also used both nota and signum as translations of the Greek σημεῖον.Footnote 14 Seneca's use of the philosophically loaded terms, disambiguating the Aeschylean εὔσημος as σημεῖον, is not coincidental.Footnote 15
At Seneca's stage of intervention, the term signum is loaded with the preceding philosophical debates in epistemology, surrounding the nature of signs and evidence: as a key word among the Epicureans and the Stoics, signum/σημεῖον has special currency.Footnote 16 I suggest that Seneca, using this utterance, shows the Chorus of Trojan women to be mis-readers of philosophy: the Trojan women's attempt at making use of Stoic or Epicurean techniques of inference in their use of signum (by seeing the smoke, the Trojans will know where the home is) would be bound to fail as philosophical argument—but it works in their tragic world.
An example used in philosophical debates about inference that is very similar to the utterance of the Trojan women occurs in Stoic logic: for the Stoics, smoke is observed in conjunction with fire, so that smoke is a sign that is observed together with what it signifies. Such a sign is recognized by the Stoics as a so-called ‘commemorative’ sign.Footnote 17 The Senecan version, however, is not a Stoic ‘commemorative’ sign. Rather, it shows people, here the Trojan women, attempting to use philosophical logic—but their way of reasoning is neither tenable from a Stoic point of view nor as an Epicurean-inspired inference relying on analogues. Their sign has no referent: what it is a sign of is lost.
This is a further Senecan moment of expressing the failure of the Chorus’ philosophizing. More precisely, the Senecan use of signum concludes the allusions to Lucretius and Epicurean thought throughout the ode: one of the points of the Senecan example is as criticism of the Epicurean analogic method of inference. According to this Epicurean method, one can draw inferences from one's observations in the spatio-temporal world to the world of atoms.Footnote 18 Seneca's use of signum in the mouth of the Trojan women, then, may suggest that the Trojans’ homeland, marked by the signum, exists as little as the atomic world the Epicureans believe in based on their naïve—the Stoic voice of Seneca suggests—way of inference.Footnote *
