Hildegard was given "equivalent canonization" by the Catholic church in 2012. She had been far too provocative and unruly to be stamped with these credentials as such and this persisted since her death in 1179 (as an 80 year old woman in the middle ages). Hildegard was simultaneously named a "Doctor of the Church" for her body of work which included being the first in a line of German mystics, a poet, prophet, preacher and teacher (unheard of in her time) and she was quick to call out injustice and do what she thought was right regardless of the dictates of popes and princes, Hildegard was a healer, using stones, herbs, nutrition and extensive medical research still in use today. She was an artist, composer and innovator ahead of her time. Hildegard was the first to study, document and describe a woman's orgasm. She introduced extensive spiritual content on the Divine Feminine. She was also excommunicated, started a community of her own and is believed by some to have been queer. Hildegard was certainly peculiar in all the right ways. Known as a polymath, she was a Renaissance figure before the time.
