I'm not quite sure what you're looking for, David, but I find in LSJ s.v.
KATAXEW, I find, even in Homer, something very close to Mk 14:3:
Iliad 23.282-3 hOS SFWIN MALA POLLAKIS hUGRON ELAION
XAITAWN KATEXEUE ...
Achilles is speaking of how his father Peleus treated a pair of horses:
"who very often would pour over their manes (XAITAWN) liquid olive oil."
It strikes me that this is essentially the same construction as in Mk 14:3.
Later instances are cited from Herodotus, Aristophanes, Homer, all using
the verb KATAXEW, an accusative of what's poured and a genitive of what it
is poured upon.
Now, of course, if one supposes that one's grammatical database ought to be
restricted to Hellenistic Greek only or to NT only, the parallel to Mk 14:3
might be harder to find!
