Bernard of Clairvaux unhesitatingly accepted the divine origin of Hildegard’s writings, and in a letter to her, which seems to have been written while the Pope’s decision was pending, he addressed her in most respectful terms[680]: ‘They tell us that you understand the secrets of heaven and grasp that which is above human ken through the help of the Holy Spirit,’ he wrote among other things. ‘Therefore we beg and entreat you to remember us before God and also those who are joined to us in spiritual union. For the spirit in you joining itself unto God, we believe that you can in great measure help and sustain us.’ Hildegard—with a mixture of self-assurance, and eagerness to justify that assurance, which is thoroughly characteristic of her—replied to Bernard in ecstatic terms[681], praised him for having preached the Cross and spoke of him as the eagle who gazes into the sun.

The correspondence[682] of Hildegard is voluminous, for from the time when her writings first gained approval from the Pope, many lay princes and dignitaries of the Church, bishops and abbots, abbesses and nuns, wrote to her, generally asking for her good opinion or for advice, but sometimes propounding questions of speculative interest, to which Hildegard in reply sent sometimes a few sentences, sometimes a long disquisition. It is largely owing to this correspondence that the fame of the abbess has spread beyond the confines of Germany. Linde, one of the few modern students who has treated of Hildegard, enumerates many manuscript copies of these letters which are preserved in the libraries of German cities, in Paris, London and Oxford. The genuineness of the letters has been questioned on the ground that all those addressed to Hildegard are curiously alike, but Linde, after examining a number of manuscript copies, came to the conclusion that the letters were genuine[683]. In their present arrangement the letters do not stand in chronological order but according to the rank of the correspondents, so that those written by Popes to Hildegard with their replies stand first, then come those written by archbishops, bishops, emperors, and so on. With few exceptions there is only one letter from each correspondent, an arrangement which suggests the work of a scribe, who for the sake of uniformity may in some instances have selected from or summarized his material. The letters printed by Migne are a hundred and forty-five in number, but Linde refers to a few more in his list with the remark that parts of the correspondence exist separately and are sometimes cited as separate works[684].

These letters of Hildegard’s, as well as her other writings, contain many references to herself; she never fails to inform us of the circumstances which led her to begin a work. She tells us that she was middle-aged when she first wrote an account of her visions, but that she had been subject to these visions from her earliest childhood, and that the mental agonies she went through before she sought relief in writing were ever present to her mind.

Moreover we are in possession of an account of her life written between 1181 and 1191, of which the first part is by Godefrid, who introduces extracts from the book ‘Scivias.’ The second and third parts are by Theodor, who uses an autobiography of Hildegard of which we have no other mention. It appears from the Acts of Inquisition of the year 1233 which were drafted to establish Hildegard’s claim to canonization, that both these monks had stayed with Hildegard.

Summarizing the contents of these different accounts and the information which the voluminous writings of the abbess supply, we gather that Hildegard, at the time when the Pope’s attention was first drawn to her, was between forty and fifty years of age; that she was a daughter of one of the landed gentry, and that she had been given into the care of the nuns of Disibodenberg at the age of seven and had made profession at fourteen. Disibodenberg[685], situated on the river Nahe, was a monastery of some importance and has preserved annals extending from 831 to 1200 which contain useful contributions to contemporary history. The house was under the rule of an abbot, but a convent of nuns had been lately added to it when Hildegard came there; this convent was under the rule of the ‘magistra’ Jutta, sister of Meginhard, Count of Sponheim. From Jutta Hildegard received her training, which included a knowledge of books of devotion, scripture and music. Apparently she could not write German[686], and in Latin her acquaintance with grammatical inflection and construction was limited[687], so that when she began to write she availed herself of the help of a monk and afterwards of that of some nuns of her convent who helped her to polish (limare) her sentences.

During the years she spent at Disibodenberg she seems to have been devoted to nursing[688], and the consecration of a chapel in the infirmary about this time leaves us to infer that there were in this monastery special conveniences for the sick[689]. In the year 1136 she succeeded Jutta as lady superior, and at once formed the plan of leaving Disibodenberg and settling some distance away on the Rupertsberg near Bingen on the Rhine, in a convent foundation of her own. But at first Kuno († 1155), abbot of Disibodenberg, opposed her going and cast doubts on the vision in which she declared she was divinely directed to do so[690], while many who did not belong to the monastery, and among them the parents of girls who had been given into her care, disapproved of their daughters being taken to a distant and desolate neighbourhood[691]. But Hildegard persisted, for the accommodation at the monastery was insufficient for herself and her numerous pupils, and besides as abbess at the Rupertsberg she would have a very different standing. She fell ill, and then, chiefly through the intercession of friends outside who made grants of land and helped her towards the erection of new buildings, the abbot was brought to agree to her wishes. Among others Heinrich, archbishop of Mainz, advocated her going, and about the year 1147 she removed to the new settlement with eighteen young women. We have a description of the influence she exerted over these girls, her spiritual daughters, when they were still at Disibodenberg. In the new home Hildegard adopted the rule of St Benedict, but she met with opposition, for some of the young women objected to the greater restrictions put upon them by the new rule, and the abbess needed the help and support of the better and wiser ones amongst them to overcome the difficulty. After the labour of moving Hildegard fell ill and lay prostrate for several years, till she was strengthened and restored by visions of the work that still lay before her.

The Acts of Inquisition tell us that there was accommodation on the Rupertsberg for fifty professed nuns (dominae), seven poor women and two priests[692], but the independence of the nunnery was not easily secured and Hildegard repeatedly travelled to Disibodenberg to settle matters. The men’s convent continued to supply priests to the women on the Rupertsberg, but as late as 1170 difficulties occurred in regard to their appointment, and we find Hildegard writing to Pope Alexander begging him to admonish the abbot of Disibodenberg in her behalf[693].

A considerable portion of ‘Scivias’ was written before Hildegard removed to the Rupertsberg. She has described in the introduction to the book how she was led to write it[694].

‘It was in my forty-third year, when I was trembling in fearful anticipation of a celestial vision, that I beheld a great brightness through which a voice from heaven addressed me: “O fragile child of earth, ash of ashes, dust of dust, express and write that which thou seest and hearest. Thou art timid, timid in speech, artless in explaining, unlearned in writing, but express and write not according to art but according to natural ability, not under the guidance of human composition but under the guidance of that which thou seest and hearest in God’s heaven above; what thus thou hearest proclaim, like a listener who understanding the words of his teacher, as this teacher wills and indicates, so gives expression to his words according to the power of his speech. Thus thou, O child of earth, proclaim what thou seest and hearest, and put it in writing, not as thou or others will it, but as He wills who knows, sees and disposes of all in the depths of His mysteries.” Again I heard a voice from heaven, saying: “Speak these wonderful things, write them in thy unlearned way, proclaim them.” And it happened in the year 1141 of Christ’s incarnation, when I was forty-two years and seven months old, that a fiery light of great brilliancy streaming down from heaven entirely flooded my brain, my heart and my breast, like a flame that flickers not but gives glowing warmth, as the sun warms that on which he sheds his rays. Then of a sudden I had the power of explaining Scripture, that is the Psalter, the Gospels and the other Catholic books both of the Old and of the New Testament (Psalterium, Evangeliorum et aliorum catholicorum tam Veteris quam Novi Testamenti volumina), though I did not understand the inflections of words, their division into syllables, their cases and tenses. I had been conscious from earliest girlhood of a power of insight, and visions of hidden and wonderful things, ever since the age of five years, then and ever since. But I did not mention it save to a few religious persons who followed the like observances with myself; I kept it hidden by silence until God in His grace willed to have it made manifest.’

In this strain she tells how her visions came to her, not when she was asleep or when she was dreaming or in any way excited, but in the most serious of moods. They had for years perturbed her, and she had shrunk from putting them into writing, when a sudden illness came upon her and made her alter her mind. Then in her own words, ‘a noble high-born girl and the man whom I had secretly sought and consulted, were witnesses to how I set my hand to the task’—that is to the composition of ‘Scivias.’
