‘The humours at times rage fiercely as a leopard and again they are softened, going backwards as a crab;[91] or they may show their diversity by leaping and goring as a stag, or they may be as a wolf in their ravening, and yet again they may invade the body of man after the manner of both wolf and crab. Or else they may show forth their strength unceasingly as a lion, or as a serpent they may go now softly, now violently, and at times they may be gentle as a lamb and at times again they may growl as an angered bear, and at times they may partake of the nature of the lamb and of the serpent.’[92] Having completed her general survey of the macrocosm (Vision II), and having investigated in detail the structure of man’s body, the microcosm, in terms of the greater universe (Vision III), and discussed the influence of the heavenly bodies on terrestrial events (Vision IV), Hildegard turns to the internal structure of the terrestrial sphere (Vision V). This vision is illustrated by the figure in the Lucca MS. reproduced in Plate XI. [Illustration: Fig. 5. From Herrade de Landsberg’s _Hortus deliciarum_, after Straub and Keller.] Upon the surface of the earth towards the east stands the building which symbolizes the _aedificium_ of the church, a favourite conception of our authoress. This church is surmounted by a halo, whence proceed a pair of pinions which extend their shelter over a full half of the earth’s circumference. As for the rest of the earth’s surface, part is within the wide-opened jaws of a monster, the Destroyer, and the remainder is beneath the surface of the ocean. Within the earth are five parts analogous, as she would have us believe, to the five senses. An eastern clear arc and a western clouded one signify respectively the excellence of the orient where Zion is situated, and the Cimmerian darkness of the occidental regions over which the shadow of the dragon is cast. Centrally is a quadrate area divided into three zones where the qualities of heat and cold and of a third intermediate ‘temperateness’ (_temperies_) are stored. North and south of this are two areas where purgatory is situate. Each is shaped like a truncated cone and composed also of three sectors. Souls are seen suffering in one sector the torment of flame, in another the torment of water, while in the third or intermediate sector lurk monsters and creeping things which add to the miseries of purgatory or at times come forth to earth’s surface to plague mankind. These northern and southern sections exhibit dimly by their identically reversed arrangement the belief in the antipodean inversion of climate, an idea hinted several times in Hildegard’s writings, but more definitely illustrated by a figure of Herrade de Landsberg (Fig. 5).
