This article examines a pair of anecdotes in the works of Suetonius and Cassius Dio, describing Nero's passionate late-career interest in the instrument known as the hydraulis or water-organ. The first half of the article contextualizes the water-organ episode in light of both the history of the instrument's reputation and the wider characterization of Nero in the literary sources. The rest of the article uses the episode to shed light on Nero's self-representation as princeps, focussing on the significance of the water-organ as both a musical instrument and a technological marvel. On the one hand, the organ's popularity with Roman audiences of the Early Imperial period made it a politically strategic choice for a music-loving emperor with strong populist leanings. On the other hand, the association of the organ with the intellectual world of Hellenistic Alexandria appealed to a certain group of Roman elites (including Nero himself), who shared a keen interest in technological innovation and technical knowledge more broadly. In the end, however, Nero's experiments with the water-organ were cleverly trivialized by hostile writers and redeployed as an illustration of the emperor's most appalling vices.

13 Our knowledge of the technical workings of the hydraulis derives mainly from the writings of Hero (Pneum. 1.42) and Vitruvius (10.8.3–6), as well as from the remains of two water-organs excavated during the twentieth century, the first from Aquincum (modern Budapest) and the second from Dion in northern Greece. On the Aquincum organ, see Hyde, W., ‘The recent discovery of an inscribed water-organ at Budapest’, TAPhA 69 (1938), 392–411Google Scholar; M. Kaba, Die römische Orgel von Aquincum (3.

14 Syll. 3 737 = Choix Delphes 192. There is an erasure in lines 8–9 of the text; Dittenberger, ad loc., restores the name of the games (i.e. Pythian) and the total prize money: τῶι ἀγῶν[ι τῶν Πυθίων δραχμαῖς χιλίαις καὶ πεντακοσίαις καὶ] εἰκόνι χαλκέαι. The inscription states that additional honours were conferred on a certain Cryton, the brother of Antipatros (lines 13–14), as well as on a group of attendants (line 20), who may have assisted Antipatros in the operation of the instrument: see A. Chaniotis, ‘A few things Hellenistic audiences appreciated in musical performances’, in M.C. Martinelli, F. Pelosi and C.

15 Cic. Tusc. 3.43. Perrot (n. 6), 45–6 speculates that Cicero might have encountered the hydraulis at some point during his travels in Greece between 79 and 77 b.c., but there is no direct evidence to support this claim.

17 Unfortunately, none of the extant iconography can be securely dated to the period before or during Nero's reign. A tiny engraved gem from the British Museum shows an organ-player accompanied by two assistants who operate the pistons (GR 1859.3–1.112; BM Cat Gems 1051). Markovits (n. 10), 39 dates it to the first century b.c., but does not say on what grounds, while Perrot dates it to the third century a.d. on the opinion of ‘experts at the British Museum’ (Perrot [n. 6], 84–5 with Plate VIII, no. 2). The hydraulis is also represented in two terracotta figurines from Tarsus and Alexandria, variously dated between the first centuries b.c. and a.d. (Perrot [n. 6], 77–8 with Plate V; 99–100 with Plate XVI, no. 1; Markovits [n. 10], 739, Taf. 5 and 6). Also noteworthy is a small graffito of an organ from a taberna in Pozzuoli, found alongside a larger graffito of a gladiator's trident; it is usually dated to the mid first century a.d. (M. Guarducci, ‘Iscrizioni greche e latine in una taberna a Pozzuoli’, in Acta of the Fifth International Congress of Greek and Latin Epigraphy, Cambridge, 1967 [Oxford, 1971], 219–23, with Plate 23a; M. Langner, Antike Graffitizeichnungen: Motive, Gestaltung und Bedeutung [Weisbaden, 2001], Taf. 153, nos. 952, 2362–3; not mentioned by Perrot [n. 6] or Markovits [n. 10]); this dating is disputed by Creese (n. 10), 571 n. 41.

19 A survey of the prosopographical entries in I.E. Stephanis, ΔΙΟΝΥΣΙΑΚΟΙ ΤΕΧΝΙΤΑΙ (Heraklion, 1988) and P. LeVen, The Many-Headed Muse: Tradition and Innovation in Late Classical Greek Lyric Poetry (Cambridge, 2014), 22–32 yields only a couple of possible exceptions. A fascinating inscription from Aquincum commemorates a female musician who apparently was proficient at both the cithara and the hydraulis (CIL 3.10501). However, the inscription suggests that the woman played the lyre in private for her husband's benefit (uox ei grata fuit pulsabat pollice cordas, line 3), in contrast with the organ, which she performed while being ‘watched by the people’ (spectata in populo, line 7). The depiction of women as skilful lyre-players is a common literary trope denoting education and domestic virtue: see E. Hemelrijk, Matrona Docta: Educated Women in the Roman Elite from Cornelia to Julia Domna (London and New York, 1999), 79–80.
20 Aulodes were singers who accompanied aulos-players.
21 It could be argued, perhaps, that Nero adopted the pipes in an attempt to assimilate himself more closely with his patron god Apollo, with whom he positively compared himself as a singer (Suet. Ner. 53). A poem by Alcman (PMG fr. 51) represents Apollo as being proficient at both the lyre and the pipes, implying that mortal musicians ordinarily lacked such proficiency.

Epictetus, Encheiridion 29.3, criticizing those who throw themselves ‘like children’ (ὡς τὰ παιδία) from one activity to the next: ‘they [i.e. children] play wrestlers, again gladiators, again they blow trumpets, and then act a play’.
26 Caligula: Philo, Leg. 44, 79, 96; Suet. Calig. 11, 54.1; Cass. Dio 59.29; Aur. Vict. Caes. 3.12; cf. Philo, Leg. 42, describing his ‘boyish’ (μειρακιωδέστερον) enthusiasm for dancers and mimes. Commodus: HA, Comm. 1.8. Elagabalus: HA, Heliogab. 32.8. Severus Alexander: HA, Alex. Sev. 27.5, 27.9. Titus, too, is said to have acquired an aptitude for singing and playing the lyre as a boy (in puero), although he was apparently careful to adhere to proper standards of decorum once he reached maturity: Suet. Tit. 3.

29 For the ‘eureka’ story, cf. Vitr. De arch. 9.praef.10; M. Jaeger, Archimedes in the Roman Imagination (Ann Arbor, 2008), 17–31. The Archimedean resonance becomes stronger if we imagine that Nero was actually speaking in Greek, the standard language of technical discourse in antiquity: see C. Roby, Technical Ekphrasis in Greek and Roman Science and Literature: The Written Machine between Alexandria and Rome (Cambridge, 2016), 80–2. Interestingly, Tertullian (De anim. 14.4) claims that the hydraulis was the invention of Archimedes and not of Ctesibius.

34 Similarly, Philostratus (V A 4.42.1) conjures an image of a scantily clad Nero singing in a tavern and compares him to ‘the most shameless of shop-keepers’ (τῶν καπήλων οἱ ἀσελγέστατοι).

47 The appearance of a hydraulis on the reverse of a fourth-century contorniate medallion, coupled with an image of Nero on the obverse, may suggest that Nero was remembered for playing the hydraulis in later times. However, this idea could be challenged on the grounds that the hydraulis also features on other contorniates of the period alongside portraits of Trajan and Caracalla on the obverse: see Perrot (n. 6), 90–1 with plate IX, nos. 1–2; Markovits (n. 10), Taf. 26a; A.

51 Petron. Sat. 51; Plin. HN 36.195; Cass. Dio 57.21.6. Revealingly, Pliny concludes his account by mentioning a new type of glass that was ‘discovered’ (reperta) during Nero's reign. Rather than prohibiting its circulation as Tiberius had done with the ‘unbreakable’ glass, he permitted it to be sold on the market but for an exorbitantly high price.

54 Hine, H.M., ‘Rome, the cosmos, and the emperor in Seneca's Natural Questions’, JRS 96 (2006), 42–72Google Scholar, at 66 cites the water-organ episode as evidence that ‘the emperor [Nero] was a serious sponsor of technological progress’. Similarly, Drinkwater (n. 8), 123 infers from the episode that Nero possessed a ‘liking for gadgets’, but does not pursue this idea further.

One might add to this list of examples the massive lake which Nero constructed in the Domus Aurea (Suet. Ner. 31.1); his vast pool extending from Misenum to Lake Avernus (Tac. Ann. 15.42; Suet. Ner. 31.3; cf. Stat. Silu. 4.3.7–8); and the collapsible boat which he used to drown Agrippina, supposedly inspired by a mechanical stage prop exhibited in the theatre (Tac. Ann. 14.3; Suet. Ner. 34.2; Cass. Dio 61.12.2).
60 Sen. QNat. 2.6.5. The loudness of the hydraulis is also suggested by an inscription from Rhodes, dating from the third century a.d., which refers to an organ-player belonging to the cult of Dionysus whose role was to ‘wake up the god’ (τῷ ὑδραύλῃ τῷ ἐπεγείροντι [τὸ]ν θεὸν): REG 17 (1904), 203 no. 1b, lines 23–4; I.Ephesos 1601a provides further evidence of the use of organs in noisy Dionysiac ritual.

67 May, J.M., ‘Seneca's neighbour, the organ tuner’, CQ 37 (1988), 240–3CrossRefGoogle Scholar interprets a phrase in Sen. Ep. 56.4 (qui ad Metam Sudantem tabulas experitur et tibias) as an oblique reference to ‘a tuner, builder, or repairer of the hydraulus’ [sic], rejecting the conventional reading tubulas [i.e. small pipes] in favour of the variant tabulas (which, in his view, represent ‘the boards of hydrauli’; cf. Vitr. De arch. 10.8.3). May proceeds to speculate further that ‘Seneca had, in fact, been one of the primores uiri who accompanied Nero on guided tours of his favourite water organs’. Such speculation is unhelpful: Seneca retired from the political scene in 62 and was put to death in 65, whereas Nero's association with the instrument is not mentioned until 68.
