Saint Catherine was a fourth-century Christian martyr and popular medieval saint. Saints were identified by their attributes (symbols). Catherine’s attribute was the wheel because the emperor condemned Catherine to death on a spiked wheel. The wheel shattered at her touch. She was beheaded with a sword. Because of her great learning, she is the patron saint of scholars. In addition to the wheel, she is often shown with a book, a sword and the palm, the symbol of martyrdom.
