Hi Trevor.
As far as ORACLE (a shrine) goes ...
RACLE is an alternative spelling of RAKEL, used by Chaucer (in Troilus and Criseyde) to mean hasty/reckless/rash. I extrapolated this to mean 'abandoned' (in the sense of 'While drunk, he behaved in an abandoned way').
I may be a step (or several) too far, though.
