What's the meaning of " elusory spot"?

That's an almost opaque passage; i wonder if it had been written by a native speaker of English. Perhaps what the author meant was "illusory," i.e., something imagined rather than real.

What the hell does 'molery' mean?

As the passage has mentioned the "signification of moles", I think it is the reading or explanation of moles.

Note that these are what some people call beauty spots. Not the digging animals.



An artist in molery was a kind of wizard or fortune teller who would "read" signs and make predictions about a person's future from the number and position of the moles on their face and body.
