Episode notes
Court Politics Turned Dangerous Under Queen Mary
- Dee's fortunes flipped under Queen Mary when his father was jailed and property seized, exposing him to risk under revived heresy laws.
- Mary announced a pregnancy, confined herself, and the court's paranoia over an heir heightened pressure on Dee's astrological work.
Horoscopes Put Dee On Trial For Treason
- Dee cast natal horoscopes for Queen Mary, King Philip and Princess Elizabeth predicting Mary's death and Elizabeth's rise, which led to his arrest for calculating the monarch's lifespan.
- He was charged with witchcraft and treason for 'compassing' the death of the queen and briefly imprisoned at Hampton Court.
Predictions Are Power Plays Not Neutral Facts
- Predictions function as power plays that claim the future rather than neutral forecasts.
- The soothsayer who tied his death to the king's shows how forecasters can make themselves indispensable or dangerous depending on whom they serve.
