Hildegard of Bingen, known to the world as the "German Prophetess," was one of the most interesting women of the Middle Ages, and she gained her fame through miraculous visions received from God. This versatile visionary has contributed much in the fields of psychology, medicine, theology, and music. Thanks to the many preserved works, today we can learn a lot about this great visionary. For Hildegard, human is always at the center. Therefore, as we listen to her works, the transmitted visions, and the voice of God from heaven speaking to her, we take on the experience of a new dimension. That is why she selflessly wrote down all her visions and conveyed them to us, the listeners and readers, in a pictorial way, so that we could better understand what she received, experienced and what she wants to convey to us. This story, in a concise way, shows us who Hildegard of Bingen was, and what importance she had in her time, but also for us today. Following her example, I tried to present the essence of this medieval visionary and her works in as simple and clear terms as possible, so that we can get to know the true character of this special woman in the most comprehensible way possible.
