Osiris is drawn from Egyptian mythology, where the god of that name was associated with death, renewal, and rule over the afterlife -- though the precise meaning of the word itself remains debated among Egyptologists. As a given name it carries an unusual weight, tied to cycles of ending and return rather than a single fixed trait.
There will neither good or evil be performed, but when the good or bad planets in a nativity or revolution shall aspect the Moon by a quadrate. - William Lilly (1602.-1681.)
