In Tudor times, divination and astrology were common practices and the casting of #horoscopes was taken very seriously. In a letter to her grandmother, Arbella Stuart (1575-1615), a claimant to Elizabeth I’s throne, mentions that she has enclosed her hair, which was cut on the “sixth day of the Moon”. This lunar precision was necessary as the hair was going to be used astrologically to cast a horoscope to foretell Arbella’s chances of becoming Queen of England.
