ψυχὰς ἐκτραχήλιζον, an allusion to the risk of a broken neck in the chariot-race. Tertull. de Spectaculis, § 9: “Equestrianism was formerly practised in a simple way on horseback, and certainly its ordinary use was innocent: but when it was dragged into the games, it passed from a gift of God into the service of demons.” The presiding deity of the chariot-race was Poseidon (Hom. Il. xxiii, 307; Pind. Ol. i. 63; Pyth. vi. 50; Soph. Œdip. Col. 712), and both this and the other shows of the Circus, and of the theatre, were connected with the worship of the gods of Greece and Rome, and therefore forbidden as idolatrous: “What high religious rites, what sacrifices precede, intervene, and follow, how many guilds, how many priesthoods, how many services are set astir” (Tert. de Spect. § 7).
