regicide, n.All

Regicide (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠the primitive motif under the alchemical parables: the old and impotent king is killed or sacrificed to renew kingly power and the fertility of the land.

Regicide (n.) lay ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠behind the killing of Moses: the Jews only repeated an evil deed that in primaeval times had been a law against the divine king — itself derived from a still older prototype.
