to the mysteries of Druids and their miracles, to the legends of bards, and it is shewn after what manner these things concurred in the formation of modern societies, thus preparing a brilliant and permanent victory for Christianity. The number four expresses Nature and force, while the letter _Daleth_, which stands for it in the Hebrew alphabet, is represented in that of the Kabalists by an emperor on his throne. The fifth book is consecrated to the sacerdotal era of the middle ages, and we are present at the dissensions and struggles of science, the formation of secret societies, their unknown achievements, the secret rites of grimoires, the mysteries of the _Divine Comedy_, the divisions within the sanctuary which must lead later on to a glorious unity. The number five is that of the quintessence, religion and the priesthood; its character is the letter _He_, represented in the magical alphabet by the symbol of a high priest. The sixth book exhibits the intervention of Magic in the work of the Revolution. The number six is that of antagonism and strife in preparation for universal synthesis, and the corresponding letter is _Vau_, symbol of the creative _lingam_ and the reaper’s sickle. The seventh book is synthetic, containing an exposition of modern workings and discoveries, new theories on light and magnetism, the revelation of the great Rosicrucian secret, the explanation of mysterious alphabets, the science of the word and its magical works, in fine, the summary of the science itself, including an appreciation of what has been accomplished by contemporaneous mystics. This book is the complement and the crown of the work, as the septenary is the crown of numbers, uniting the triangle of idea to the square of form. Its corresponding letter is _Zain_, and the Kabalistic hieroglyphic is a victor mounted on a chariot, drawn by two sphinxes.[22]
