Chadwick & Ventris 1973: "a bronze ewer or 'oinochoe' of the type usual in the surviving bronze hoards: these generally show a horizontal ring 2/3 of the way from handle to base, to help in pouring (cf. κορωνόFεσσα Ta 711?). Palmer's comparison with πέλανος 'funerary libation' would apparently involve an unetymological use of q-. Alternately cf. Old Norse huerna 'pot', Gothic hwairnei (fem.) 'cranium' (cf. Lat. testa)?"
Palmer TBD: funerary libation cf. πέλανος
