Black Cat in Kap Arkona

The view of black cats being favorable creatures is attributed specifically to the Egyptian goddess Bast, the cat goddess. Egyptian households believed they could gain favor from Bastet by hosting black cats in their household. This view was held in the early 17th Century by the English monarch Charles I. Upon the death of his treasured pet black cat, he is said to have lamented that his luck was gone. True to his claim, he was arrested the very next day and charged with high treason.
