On 11th November, 1572, Tycho noticed an unfamiliar bright star in the constellation of Cassiopeia, and continued to observe it with a sextant. It was a very brilliant object, equal to Venus at its brightest for the rest of November, not falling below the first magnitude for another four months, and remaining visible for more than a year afterwards.
On 2 July 1505, while Luther was returning to university on horseback following a trip home, a lightning bolt struck near him during a thunderstorm. He later told his father that he was terrified of death and divine judgment, and he cried out, “Help! Saint Anna, I will become a monk!” He came to view his cry for help as a vow that he could never break.
