διαταχθέντες, ‘to their two posts,’ i. e. Artemisium and Thermopylae.
The oracle is said to have been (Clem. Alex. Stromateis, p. 753, Potter) ὦ Δελφοὶ λίσσεσθ᾽ ἀνέμους καὶ λώιον ἔσται. For a similar oracle cf. ch. 189, and for their fulfilment ch. 188 f.; viii. 12 f.
The words ἐξαγγείλαντες χάριν ἀθάνατον κατέθεντο, making a hexameter, are probably a reminiscence of some poetical narrative of this event, or of a dedicatory inscription on a thank-offering at Delphi to the winds. For similar reminiscences cf. ch. 169. 2 n.; Verrall, Cl. Rev. xvii. 98 f.
Θυίη: daughter of Cephisus (or according to Delphic legend of Castalius; cf. Paus. x. 6. 4) and mother by Apollo of Delphus. She was believed to have been the first to sacrifice to Dionysus, hence the Attic and Delphic women who served that god with orgiastic rites were called Θυῖαι or Θυιάδες (distinguished by Rapp from the purely mythological Maenads); cf. Paus. x. 6. 4. The name means ‘stormy’ (cf. θύελλα); hence she is naturally connected at Delphi with the winds.
