The concentric circles appear in numerous visions, and notably in that of the _Days of the Creation of the World and the Fall of Man_, illustrated by what is perhaps the most beautiful of all the miniatures of the Wiesbaden Codex B (lib. ii, vis. 1, Plate XXII). It is in this concentric form that Hildegard most frequently pictures the Almighty, and the idea again appears in the eleventh miniature, here reproduced in its original colours, which she describes as ‘a most shining light and within it the appearance of a human form of a sapphire colour which glittered with a gentle but sparkling glow’ (lib. ii, vis. 2, Plate XXIII). Appearances of this type are recorded again and again. The type with fortification figures is encountered in a whole series of visions, of which we reproduce the account and illumination of the _Zelus Dei_ (lib. iii, vis. 5, Plate XXIV, lower section). ‘I looked and behold a head of marvellous form ... of the colour of flame and red as fire, and it had a terrible human face gazing northward in great wrath. From the neck downward I could see no further form, for the body was altogether concealed ... but the head itself I saw, like the bare form of a human head. Nor was it hairy like a man, nor indeed after the manner of a woman, but it was more like to a man than a woman, and very awful to look upon. ‘It had three wings of marvellous length and breadth, white as a dazzling cloud. They were not raised erect but spread apart one from the other and the head rose slightly above them ... and at times they would beat terribly and again would be still. No word uttered the head, but remained altogether still, yet now and again beating with its extended wings.’ From the head extended a series of fortification lines, and this peculiar form of vision is reproduced on several occasions and variously interpreted (Plate XXIV, upper section). It is united with similar visions in what we regard as a reconstructed conception of exceedingly complex structure. This she claims to see separately, and she interprets it as the _aedificium_ of the city of God (Plate XXV). Such reconstructed visions are clearly of a different type and origin to the simple group in which a shining light or group of lights is encountered and interpreted as a speaking figure. [Illustration: From THE WIESBADEN CODEX B fo. 30 r Plate XXV. THE HEAVENLY CITY] Hildegard’s visions, perhaps without exception, contain this element of a blinding or glittering light, which she interprets in a more or less spiritual manner. We terminate our account with the passage in which she sums up her experiences of it.
