1. The Spiritual Tabernacle (called by Surius _In Tabernaculum Mosis_).—The longest, most fantastic, and, in spite of some fine passages, the least interesting of Ruysbroeck’s works. Probably founded upon the _De Arca Mystica_ of Hugh of St. Victor, this is an elaborate allegory, thoroughly mediæval in type, in which the Tabernacle of the Israelites becomes a figure of the spiritual life; the details of its construction, furniture and ritual being given a symbolic significance, in accordance with the methods of interpretation popular at the time. In this book, and perhaps in the astronomical treatise appended to _The Twelve Béguines_ (No. 11), I believe that we have the only surviving works of Ruysbroeck’s first period; when he had not yet ‘transcended images,’ but was at that point in his mystical development in which the young contemplative loves to discern symbolic meanings in all visible things. 2. The Twelve Points of True Faith (_De Fide et Judicio_).—This little tract is in form a gloss upon the Nicene Creed; in fact, a characteristically Ruysbroeckian confession of faith. Without ever over-passing the boundaries of Catholic doctrine, Ruysbroeck is here able to turn all its imagery to the purposes of his own vision of truth. 3. The Book of the Four Temptations (_De Quatuor Tentationibus_).—The Four Temptations are four manifestations of the higher egotism specially dangerous to souls entering on the contemplative life: first, the love of ease and comfort, as much in things spiritual as in things material; secondly, the tendency to pose as the possessor of special illumination, with other and like forms of spiritual pretence; thirdly, intellectual pride, which seeks to understand unfathomable mysteries and attain to the vision of God by the reason alone; fourthly,—most dangerous of all—that false ‘liberty of spirit’ which was the mark of the heretical mystic sects. This book too may well have been written before the retreat to Groenendael.
