1 This article is based on a paper that was presented at the 103rd Annual Conference of the College Arts Association, New York, 14 February 2015. It has benefited from the advice and suggestions of many friends and colleagues. I am especially grateful to Benjamin Anderson, Diliana Angelova, Francesca Dell'Aqua, Beate Fricke, Anneka Lenssen, Ruth Macrides, Yael Rice, Paul Stephenson and the anonymous reviewer. When I began this project, I held a pre-doctoral Institutional Fellowship from the Kress Foundation at the Kunsthistorisches Institute in Florence. At the time of submission, I held a David E. Finley fellowship at the Center for Advanced Study in the Visual Arts at the National Gallery, in Washington, DC. At publication, I was a postdoctoral fellow at the Society of Fellows in the Humanities at the University of Southern California.

3 Scholars have debated when the Serpent Column was moved to the hippodrome. Stichel and Stephenson note that while early sources are ambiguous, the column was in all likelihood moved to Constantinople by the emperor Constantine. See Stichel, ‘Schlangensäule’, 316–319; Stephenson, Serpent Column, 111–5. Albrecht Berger suggests it may have been moved to its present location only after 1261, see Berger, A., ‘The hippodrome of Constantinople in popular belief and folklore’, in Pitarakis, B.

Hārūn Ibn Yaḥyā, in Constantinople 911–3, mentions a talisman against snakes consisting of four brass serpents biting their own tails. Scholars generally agree that this passage probably does not describe the Serpent Column, see Dawkins, ‘Ancient statues’, 234, n. 51, Madden, ‘Serpent Column’, 113, and Stephenson, Serpent Column, 123.

7 E.g., Mango, C., ‘Antique statuary and the Byzantine beholder’, Dumbarton Oaks Papers 17 (1963) 53, 55–75CrossRefGoogle Scholar, and Dawkins, ‘Ancient Statues’, 244–5. More recent scholars have taken this approach more tactfully, e.g., Madden, ‘Serpent Column’, esp. 111, 120–3; and Berger, ‘Hippodrome’, esp. 205; idem, ‘Magical Constantinople: Statues, legends, and the end of time’, Scandinavian Journal of Byzantine and Modern Greek Studies 2 (2016) 9–29Google Scholar.

8 Cf. Stephenson, Serpent Column, 185. While Finbarr Barry Flood's study of apotropaia maintains differences between apotropaia and talismans, it does not attend to those differences, as ‘boundaries between these categories are rather fluid,’ see Flood, F. B., ‘Image against nature: Spolia as apotropaia in Byzantium and the dār al-Islām’, The Medieval History Journal 9, n. 1 (2006) 143–66, here, n.32, 151Google Scholar.

9 Christopher Faraone makes this distinction for ancient Greece, see Faraone, C., Talismans and Trojan Horses: Guardian Statues in Ancient Greek Myth and Ritual (New York 1992) 3–12Google Scholar. Faraone notes that while the adjective apotropaios appears in ancient Greek texts, it typically describes deities and sacrifices, and not stationary objects.

10 Some suggest that to be effective apotropaia must be seen, whereas talismans do not, e.g., Flood, ‘Image’, 151; Faraone, Talismans, 4. However, a cross or phylactery worn close to the body effectively retains its apotropaic, non-talismanic function, even if it remains completely hidden.

52 The fire of August 1203 burned down much in the vicinity of the hippodrome, but not the hippodrome itself. Crusaders stole or melted down much of the bronze statuary once there, as Niketas Choniates describes in his De signis (see above). Locals may have further dilapidated the hippodrome, see Madden, T.

53 Although Madden suggests that the fountain may have still been running at the time of the Fourth Crusade, he doubts that it would have continued in operation, adding that it had ‘certainly run dry long before the fifteenth century’, see Madden, ‘Serpent Column’, 120–2, here, 122. Many of the main long-distance water lines were non-functional. Some, such as the Valens line (or sections of it), apparently continued to flow with water, ‘even if the supply was more limited and was primarily for agricultural use’, see Crow, J., Bardill, J., and Bayliss, R., The Water Supply of Byzantine Constantinople (London 2008) 22Google Scholar.

86 See, for example, Ritter and Plessner, ‘Picatrix’, 7–9 and 91–4; the explanation here is similar to that in Ibn Waḥshiyya, Al-filāḥah al-nabaṭīyah (Nabatean Agriculture), 1283, trans. in Hämeen-Anttila, Last Pagans, 191. As noted above, a talismanic object's attractive force could also be explained in terms of magnetism, see Synesios of Cyrene, cit. and trans. in Greenfield, Traditions of Belief, 177.

87 Different alloys of bronze existed in the ancient world. Pliny notes that the ancient Greeks favoured alloys invented on Delos and Aegina and the bronze of Corinth, see Pliny, Historia naturalis 34.8–10. Lead was added to Roman bronzes to lower the melting point.
