Joanna of Castile's Vase

Origin
Joanna, known as Joanna the Mad, was queen regnant of Castile from 1504 and of Aragon from 1516. From the union of these two crowns modern Spain evolved. Joanna married Philip the Handsome, who was crowned King of Castile in 1506, initiating the rule of the Habsburgs in Spain. After Philip's death that same year, Joanna was deemed mentally ill and was confined to a nunnery for the rest of her life. Though she remained the legal queen of Castile throughout this time, her father, Ferdinand II of Aragon, was regent until his death, when she inherited his kingdom as well. From 1517, her son, Charles, ruled as king, while she nominally remained co-monarch.

This church vase was used personally by Joanna, when she was confined to being a nun. The vase somehow became imbued with her mental instability.
