But I, though I saw and heard these things, refused to write for a long time through doubt and bad opinion and the diversity of human words, not with stubbornness but in the exercise of humility, until, laid low by the scourge of God, I fell upon a bed of sickness; then, compelled at last by many illnesses, and by the witness of a certain noble maiden of good conduct [the nun Richardis von Stade] and of that man whom I had secretly sought and found, as mentioned above, I set my hand to the writing. While I was doing it, I sensed, as I mentioned before, the deep profundity of scriptural exposition; and, raising myself from illness by the strength I received, I brought this work to a close – though just barely – in ten years. (...) And I spoke and wrote these things not by the invention of my heart or that of any other person, but as by the secret mysteries of God I heard and received them in the heavenly places. And again I heard a voice from Heaven saying to me, 'Cry out therefore, and write thus!'
Hildegard has also become a figure of reverence within the contemporary New Age movement, mostly because of her holistic and natural view of healing, as well as her status as a mystic. Though her medical writings were long neglected, and then studied without reference to their context, she was the inspiration for Dr. Gottfried Hertzka's "Hildegard-Medicine", and is the namesake for June Boyce-Tillman's Hildegard Network, a healing center that focuses on a holistic approach to wellness and brings together people interested in exploring the links between spirituality, the arts, and healing. Her reputation as a medicinal Writer and healer was also used by early feminists to argue for women's rights to attend medical schools. Hildegard's reincarnation has been debated since 1924 when Austrian mystic Rudolf Steiner lectured that a nun of her description was the past life of Russian poet Philosopher Vladimir Soloviev, whose Sophianic visions are often compared to Hildegard's. Sophiologist Robert Powell writes that hermetic astrology proves the match, while mystical communities in Hildegard's lineage include that of Artist Carl Schroeder as studied by Columbia Sociologist Courtney Bender and supported by reincarnation researchers Walter Semkiw and Kevin Ryerson.
Several manuscripts of her works were produced during her lifetime, including the illustrated Rupertsberg manuscript of her first major work, Scivias (lost since 1945); the Dendermonde Codex, which contains one version of her musical works; and the Ghent manuscript, which was the first fair-copy made for editing of her final theological work, the Liber Divinorum Operum. At the end of her life, and probably under her initial guidance, all of her works were edited and gathered into the single Riesenkodex manuscript.
Recordings and performances of Hildegard's music have gained critical praise and popularity since 1979. See Discography listed below.
Hildegard was the subject of a 2012 fictionalized biographic novel Illuminations by Mary Sharratt.
A feature documentary film, The Unruly Mystic: Saint Hildegard, was released by American Director Michael M. Conti in 2014.
Hildegard was one of the first persons for whom the Roman canonization process was officially applied, but the process took so long that four attempts at canonization were not completed and she remained at the level of her beatification. Her name was nonetheless taken up in the Roman Martyrology at the end of the 16th century. Her feast day is 17 September. Numerous popes have referred to Hildegard as a saint, including Pope John Paul II and Pope Benedict XVI.
