the mythic conjunction or marriage between Sun and Moon describes a potential of inner relationship… the hero has a strange or portentous birth; he is usually fathered by a god on a mortal mother… one of the characteristics of the hero is that he is a hybrid between human and divine, and is thus destined to be a pontifex.
Greene establishes the formal template of the solar heroic trajectory, outlining its canonical stages — divine birth, hybrid nature, and the vocation of pontifex — drawn from Campbell and mapped explicitly onto astrological solar symbolism.
