Bezoar, c. 1600
Bezoars are concretions found in the stomachs of ruminants. Smaller ones were ground up and used for medicinal purposes. Many different craftsmen were involved in the decoration of these sought-after curiosities. Charles V possessed an elaborately set bezoar and there were two examples in Rudolf II’s chamber of art and curiosities. These objects were the expression of a combination of scientific interest and occult beliefs.
