  8. Brahe was poisoned with mercury on the orders of Christian IV, the King of Denmark, because the astronomer had an affair with his mother. • It is even suggested that Shakespeare used the alleged liaison as an inspiration for Hamlet. • It was believed that that his cousin slipped mercury into Brahe's drink. Tests on his hair showed mercury levels one hundred times above normal as a result of ingesting a large quantity of the liquid metal about 13 hours before his death, coinciding with the visit from his cousin.
