"Hildegard of Bingen was a 12th-century nun, mystic, prophet, and healer. She led an abbey, communed with God, advised royalty, and chastised emperors. She also made cookies.
Committed to a hermitage from the age of eight, Hildegard rose to prominence as a result of her divine visions. In a series of books, she relayed messages from God that ranged from the metaphysical to the practical. Along with fiery depictions of the world as a “cosmic egg” enveloped in the flames of God’s love, Hildegard’s books included divinely inspired recipes said to cure everything from leprosy to lung disease to the common cold.
"Whether or not you believe Hildegard communed with God, she was blessed with a unique education in the healing arts. Born on the cusp of the prosperous 12th century, she was poised to reap the benefits of a booming era in European history. “It was just this far-out time,” Sweet says, adding that Hildegard was born into an era of scholastic advancement, population growth, and agriculturally beneficial weather. Although she would have lived separate from the men at the coed Disibodenberg monastery, Sweet notes that Hildegard would have likely communicated with educated monks and had access to the library, the medicinal garden, and the infirmary. The result was an education that rivaled those of leading medieval minds.
