Today is the feast day of St. Hildegard. Hildegard was born around 1098 AD and began having visions at an early age. Likely due to this, she entered the Benedictine monastery at Disibodenberg young, part of a community of women attached to the monetary). The education that she received there helped her flower. Particularly interested in medicine, she wrote some of the earliest botanical texts in Germany and is considered the founder of German natural science.
But she is best remembered as a composer of sacred music. It is very old but has a serene beauty that I find quite compelling.
