How did St. Catherine of Alexandria die?

Researchers have little doubt that Catherine of Alexandria was a real person. However, much of the information surrounding her life and martyrdom are probably fabrications or, at the very least, exaggerations . It is believed that she was beheaded after other means of execution failed. Her name was removed from the Calendar of Saints in 1969 but returned to its former status when a diary purported to be written by Catherine, was found in the 1980s.
