Nobilissima Viriditas is the third volume of the Complete von Bingen. Hildegard was a highly respected writer, poet, composer and visionary in the 1140's and was much sought - after for her counsel by popes, regents and bishops. Her lyrics are all in Latin and they abound with images from nature, using leaves, branches and flowers to communicate overlapping themes of energy, vigour, blooming manhood, virginity and virtue.
