Therefore, although in the following pages an attempt is made to estimate her scientific views, yet the writer is conscious that such a method must needs interpret her thought in a partial manner. Hildegard, indeed, presents to us scientific thought as an undifferentiated factor, and an attempt is here made to separate it by the artificial but not unscientific process of dissection from the organic matrix in which it is embedded.

The extensive literature that has risen around the life and works of Hildegard has come from the hands of writers who have shown no interest in natural knowledge, while those who have occupied themselves with the history of science have, on their side, largely neglected the period to which Hildegard belongs, allured by the richer harvest of the full scholastic age which followed. This essay is an attempt to fill in a small part of the lacuna.

II. Life and Works

Hildegard of Bingen was born in 1098, of noble parentage, at Böckelheim, on the river Nahe, near Sponheim. Destined from an early age to a religious life, she passed nearly all her days within the walls of Benedictine houses. She was educated and commenced her career in the isolated convent of Disibodenberg, at the junction of the Nahe and the Glan, where she rose to be abbess. In 1147 she and some of her nuns migrated to a new convent on the Rupertsberg, a finely placed site, where the smoky railway junction of Bingerbrück now mars the landscape. Between the little settlement and the important mediaeval town of Bingen flowed the river Nahe, spanned by a bridge to which still clung the name of the pagan Drusus (see Fig. 1). At this spot, a place of ancient memories, secluded and yet linked to the world, our abbess passed the main portion of her life, and here she closed her eyes in the eighty-​second year of her age on September 17, 1180.

Hildegard was a woman of extraordinarily active and independent mind. She was not only gifted with a thoroughly efficient intellect, but was possessed of great energy and considerable literary power, and her writings cover a wide range, betraying the most varied activities and remarkable imaginative faculty. The best known, and in a literary sense the most valuable of her works, are the books of visions. She was before all things an ecstatic, and both her Scivias (1141–50) and her Liber divinorum operum simplicis hominis (1163–70) contain passages of real power and beauty. Less valuable, perhaps, is her third long mystical work (the second in point of time), the Liber vitae meritorum (1158–62). She is credited with the authorship of an interesting mystery-​play and of a collection of musical compositions, while her life of St. Disibode, the Irish missionary (594–674) to whom her part of the Rhineland owes its Christianity, and her account of St. Rupert, a local saint commemorated in the name ‘Rupertsberg’, both bear witness alike to her narrative powers, her capacity for systematic arrangement, and her historical interests. Her extensive correspondence demonstrates the influence that she wielded in her own day and country, while her Quaestionum solutiones triginta octo, her Explanatio regulae sancti Benedicti, and her Explanatio symboli sancti Athanasii ad congregationem sororum suorum give us glimpses of her activities as head of a religious house.

Her biographer, the monk Theodoric, records that she also busied herself with the treatment of the sick, and credits her with miraculous powers of healing.[1] Some of the cited instances of this faculty, as the curing of a love-​sick maid,[2] are, however, but manifestations of personal ascendancy over weaker minds; notwithstanding her undoubted acquaintance with the science of her day, and the claims made for her as a pioneer of the hospital system, there is no serious evidence that her treatment extended beyond exorcism and prayer.

For her time and circumstance Hildegard had seen a fair amount of the world. Living on the Rhine, the highway of Western Germany, she was well placed for observing the traffic and activities of men. She had journeyed at least as far north as Cologne, and had traversed the eastern tributary of the great river to Frankfort on the Main and to Rothenburg on Taube.[3] Her own country, the basin of the Nahe and the Glan, she knew intimately. She was, moreover, in constant communication with Mayence, the seat of the archbishopric in which Bingen was situated, and there has survived an extensive correspondence with the ecclesiastics of Cologne, Speyer, Hildesheim, Trèves, Bamberg, Prague, Nürnberg, Utrecht, and numerous other towns of Germany, the Low Countries, and Central Europe.
