"As opposed to 'Dionysian.' And both rather Procrustean I'm sorry to say.  People tend to simplify 'Apollonian' into 'mild,' and 'calm,' and 'cool.' But 'Apollonian' and 'Dionysian' are two sides of the same coin - a nun on her knees in her cell, holding perfectly still and her facial muscles relaxed, can be in a religious ecstasy more frenzied than any priestess of Pan Priapus celebrating the vernal equinox.  Ecstasy is in the skull, not in the setting-up exercises." Jubal frowned. "Another common error is to identify 'Apollonian' with 'good' - merely because our most respectable sects are all rather Apollonian in ritual and precept.  Mere local prejudice.  Proceed."
