俄狄浦斯 is the standard Mainland transliteration of 'Oedipus', the Greek mythological king who unknowingly killed his father and married his mother. Freud borrowed the name for the
俄狄浦斯情结 (Oedipus complex). Taiwan tends to use
伊底帕斯 instead. The full Freudian phase is also called
性器期 (xìngqìqī) 'phallic stage'.
