In his Lives of Eminent Philosophers (6.75–6)Footnote 2 Diogenes Laertius mentions, among the various traditions of how Diogenes the Cynic met his end, the belief that he committed suicide by retention of the breath. He cites as his authority for this the poet Cercidas of Megalopolis (c.290–post 215 b.c.e.),Footnote 3 who, between some fifty and a hundred years after the death of the Cynic, celebrated his ascent to heaven in the following verses:Footnote 4
… Quite unlike thatFootnote 5 was the great man who hailed from Sinope (he carried only his staff; his garb was a cloak doubled over; he who dined and supped under the bright sky); no, he made his ascent by clenching his teeth over his lips, and biting off his breath. For he was in truth a son of Zeus and the heavenly dog.Footnote 6
In his ascent to heaven (3 ἀνέβα) and in his subsequent conversion into a star—in this case into the star Sirius, or ‘Dog Star’ (Canis Maior)—, Cercidas seems to be following an older tradition on Diogenes’ catasterism.Footnote 7 It may already have been present in the epigram which could be read at the funeral tomb, erected in his honour at the gates of Corinth by the men of influence of the city.Footnote 8 The conversion into the ‘heavenly dog’ (5 οὐράνιος … κύων) is preceded by a characterization of Diogenes the mortal man (1 ὁ πάρος … Σινωπεύς). Cercidas makes use of three epithets in the hymnic style,Footnote 9 which refer to three elements singling him out, later to become characteristic of his followers, the Cynics:Footnote 10 the stick (βακτροφόρας), the double cloak (διπλοείματος) and, thanks to the knapsack he used to carry, his habit of ‘eating under the open sky’ (αἰθεριβόσκας).
In my opinion, this is the most reasonable interpretation of the enigmatic epithet αἰθεριβόσκας.Footnote 11 Indeed, since Diogenes did not own a house, he did not distinguish between public and private spaces that regulated life in the cities, and he did everything outdoors.Footnote 12 Additionally, the interpretation of αἰθέρι– as locative dative finds two striking parallels: the compound epithet ἀερίοικοι, which appeared in an unspecified comedy by Eubulus as the third element of a tricolon close to that of Cercidas (fr. 137.1 K.–A. ἀνιπτόποδες χαμαιευνάδες ἀερίοικοι);Footnote 13 and the sentence καὶ ἐν ἀέ[ρι] τ̣έθραμμαι in P.Genev. inv. 271, col. iii.45–6 Martin, which belongs to a dialogue, Cynic in its sentiments, between Alexander and the Brahmans.Footnote 14 Therefore, αἰθέρι– can be perfectly understood as a synonym of ἀέρι in these passages, thus providing the meaning of ‘air’.Footnote 15
Nevertheless, the catasterism alluded to in the following lines provides the compound αἰθεριβόσκας with a second meaning, appropriate to the new status of Diogenes after his death:Footnote 16 if its first meaning is a result of what the Cynic did during his life, then, after his conversion into the heavenly dog (5 οὐράνιος κύων), it can be reinterpreted as ‘feeding in the sky’ or, better, ‘in the ether’, now giving αἰθέρι– its original and more limited meaning. The first known translation of the compound, by Benedetto Brugnoli, fits with this amphibology of the epithet: pascens in aethere.Footnote 17
Further evidence for this second interpretation of the compound promoting the specific meaning of αἰθήρ is provided by the etymology of the name of Diogenes as Zανὸς γόνος in line 4: the Cynic αἰθεριβόσκας is the son of Zeus αἰθέρι ναίων.Footnote 18 This genealogy—possibly the origin of the idealized tradition of Diogenes as a θεῖος ἀνήρ who accomplishes a divine mission among men—Footnote 19 prompts the reader to associate him with a particular son of Zeus, whom the Cynic regarded as his model in life, namely Heracles.Footnote 20 He was the hero who rid human life of monsters and impurities, and who, on seeing that it was pointless to continue living, decided to commit suicide, just like Diogenes. The choice of the phrase Zανὸς γόνος among all the expressions used to refer to the offspring of Zeus—namely Διὸς/Zηνὸς παῖς, τέκνον, ἔκγονος, κοῦρος/κούρη, γένος, γόνος, γένεθλον—is probably an allusion to the hero as well. According to the documentation at our disposal, before Cercidas the phrase had been employed only once by Homer (Il. 14.449) of a great grandson of Zeus, Idomeneus, and twice by Sophocles in Trachiniae with reference to Heracles, whose father, as the hero himself proclaims, ‘is Zeus, lord of the starry sky’ (1106 ὁ τοῦ κατ’ ἄστρα Zηνὸς αὐδηθεὶς γόνος).Footnote 21 The link between Diogenes and Heracles would have been even stronger if we could assume that Cercidas had actually known the tradition which recognized an image (εἴδωλον) of the hero in the constellation of the ‘Kneeler’ (ὁ ἐν γόνασιν), raised up by Zeus to heaven as a reward for one of his ἆθλα.Footnote 22
However, between Diogenes and Heracles there is a distinctive trait which concerns their respective statuses in the remote ether.Footnote 23 On the one hand, the Cynic, on becoming the star of Sirius, will reside in the ether and not in the Underworld (cf. Anth. Pal. 7.64.4 νῦν δὲ θανὼν ἀστέρας οἶκον ἔχει), while, on the other, it is not exactly Heracles himself who will live in the starry ether but, at best, a ghostly image of him, as the true god will live in a palace on Mt Olympus in the company of his wife Hebe.Footnote 24 Thus, ether will be the abode of the true Diogenes and of the spectral Heracles.
In this regard, I am inclined to think that Cercidas has adapted the motif of the dwelling in the ether not from HeraclesFootnote 25 but from other offspring of Zeus: the Dioscuri (Διόσκουροι), whose name—and this may be relevant—also means ‘sons of Zeus’.Footnote 26 Their abode in the ether after leaving the world of the mortals was known of old,Footnote 27 but it was Euripides who gave it a special prominence. In Electra, the Chorus insist on it when they salute Queen Clytemnestra, chanting ‘sister of the two brave sons of Zeus, who live among the stars in the burning ether!’ (El. 990–2 τοῖν ἀγαθοῖν ξύγγονε κούροιν | Διός, οἳ φλογερὰν αἰθέρ’ ἐν ἄστροις | ναίουσι). In Helen, Teucer explains to Helen—who does not know the whereabouts of her brothers—the rumour that ‘they have become gods who resemble stars’ (Hel. 140 ἄστροις σφ’ ὁμοιωθέντε φάσ’ εἶναι θεώ). The expression is ambiguous: we cannot be certain whether Euripides alludes to their becoming the constellation Gemini—of which there is sure evidence only in the Hellenistic and in the Roman periods—or if they have not yet turned into stars but only resemble them when appearing to sailors-in-need in the guise of St Elmo's Fire.Footnote 28 The same ambiguity is revealed by the references to the twins in Trojan Women (Tro. 1000–1 Κάστορος νεανίου | τοῦ συζύγου τ’ ἔτ’ ὄντος, οὐ κατ’ ἄστρα πω) and in Iphigenia in Aulis (IA 768–9 τῶν ἐν αἰθέρι δισ|σῶν Διοσκούρων). Near the end of Helen, before the epiphany of the Dioscuri, the Chorus sing a propemptikon asking them to save Helen crossing the ether with their horses as δαίμονες, ‘who dwell in the heavens beneath the whirling of the bright stars’Footnote 29 (Hel. 1495–500 μόλοιτέ ποθ’ ἵππιον οἶμον | δι’ αἰθέρος ἱέμενοι, | παῖδες Τυνδαρίδαι, | λαμπρῶν ἀστέρων ὑπ’ ἀέλ|λαις οἳ ναίετ’ οὐράνιοι, | σωτῆρε τᾶς Ἑλένας). When they finally appear on stage, they announce to Helen (1666–9) that she is to share a cult with them, perhaps the same cult Apollo refers to in the epilogue of Orestes,Footnote 30 where he assigns her an abode, together with her brothers, ‘in remote ether’ (Or. 1635–7 Zηνὸς γὰρ οὖσαν ζῆν νιν ἄφθιτον χρεών, | Κάστορί τε Πολυδεύκει τ’ ἐν αἰθέρος πτυχαῖς | σύνθακος ἔσται. Cf. Or. 1683–5).
We know that Cercidas made extensive use of Euripides. His second meliamb (2 Livrea = 2 Lomiento = 5 Powell) begins with a reflection on Euripides, fr. 929a Kannicht δισσὰ πνεύματα πνεῖς, Ἔρως, as the starting point to develop the image of the ship of love's voyage through a calm sea and a stormy one (cf. Cercidas 2.11 εὖ λέγων Εὐριπίδας).Footnote 31 Furthermore, reminiscences of Euripides’ Antiope have been detected in the third meliamb (3 Livrea = 3 Lomiento = 7 Powell);Footnote 32 in Amphion, one of the characters of this play, Cercidas may have recognized a forerunner of his own political and musical activity. He may therefore have also read some of these plays where he mentions the Dioscuri—namely Helen Footnote 33 but Electra, Trojan Women, Iphigenia in Aulis and Orestes as well—,Footnote 34 thus benefitting both from the etymology of their name as ‘sons of Zeus’ and from their abode in the ether to envisage Diogenes’ catasterism and to coin a compound epithet as polyvalent as αἰθεριβόσκας.
