[1] Similarly in Photius, Lexicon kappa536 Theodoridis (but without 'Attic-speakers': for that cf. Moeris).
[2] Quotation not identified by Adler but identifiable via the TLG as Procopius, History of the Wars of Justinian 8.14.37 (though he uses the form kraugmo/s; cf. web address 1). Aelian, De natura animalium 1.38, reports that the Romans used a similar defense in their war with Pyrrhus (reference supplied by Nick Nicholas). Procopius notes that the dangling pig tactic was used successfully by the Romans in their defense of Edessa (cf. epsilon 207) in 544 CE (cf. Kaldellis (494-495) and epsilon 52), but that they did not need to resort to the stratagem again during the 551 defense of Archaiopolis (in Lazike/Kolchis (cf. kappa 1979), present-day western Georgia; Barrington Atlas map 87 grid H2), when one of the Persian war elephants panicked, scattering the attackers.
