'There is little information about the Philistien language - we only
know that the cities of their pentapolis were headed by a local
magistrate called seren and that ko:ba was their word for helmet,
which is usually compared to Hittite kupah_i for the same meaning - ...'

Palmer, Leonard Robert
The Greek language, p. 92
'A good example involves a technical word which has the additional
interest of possible Anatolian origin: kúmbakos 'crown of a helmet'
(cf. Hittite kupahhi). In O 536 kúmbakon akrótaton núks' égkheï
oksuóenti 'he struck the top of the helmet with his sharp spear', the
word is used authentically. But in E 585-6 ékpese díprou ... kúmbakos
en koníe:sin' he fell from the chariot head first in the dust' the
sense of the word is completely misunderstood. Opinions may differ
over the 'lateness' of the grotesque elaborations which follow; Mydon
the charioteer remains upright with his head buried in the sand until
the horses kick him over.'
