In other words, this vision, known to the Jews as the "Mercaba,"[336] belongs to the Cabala, where a particular interpretation is placed on each figure so as to provide an esoteric meaning not perceptible to the uninitiated.[337] The masonic coat-of-arms is thus entirely Cabalistic; as is also the seal on the diplomas of Craft Masonry, where another Cabalistic figure, that of a man and woman combined, is reproduced.[338] Of the Jewish influence in Masonry after 1717 I shall speak later. To sum up, then, the origins of the system we now know as Freemasonry are not to be found in one source alone. The twelve alternative sources enumerated in the _Masonic Cyclopædia_ and quoted at the beginning of this chapter may all have contributed to its formation. Thus Operative Masonry may have descended from the Roman Collegia and through the operative masons of the Middle Ages, whilst Speculative Masonry may have derived from the patriarchs and the mysteries of the pagans. But the source of inspiration which admits of no denial is the Jewish Cabala. Whether this penetrated to our country through the Roman Collegia, the _compagnonnages_, the Templars, the Rosicrucians, or through the Jews of the seventeenth and eighteenth centuries, whose activities behind the scenes of Freemasonry we shall see later, is a matter of speculation. The fact remains that when the ritual and constitutions of Masonry were drawn up in 1717, although certain fragments of the ancient Egyptian and Pythagorean doctrines were retained, the Judaic version of the secret tradition was the one selected by the founders of Grand Lodge on which to build up their system. 6 THE GRAND LODGE ERA Whatever were the origins of the Order we now know as Freemasonry, it is clear that during the century preceding its reorganization under Grand Lodge of London the secret system of binding men together for a common purpose, based on Eastern esoteric doctrines, had been anticipated by the Rosicrucians. Was this secret system employed, however by any other body of men? It is certainly easy to imagine how in this momentous seventeenth century, when men of all opinions were coalescing against opposing forces--Lutherans combining against the Papacy, Catholics rallying their forces against invading Protestantism, Republicans plotting in favour of Cromwell, Royalists in their turn plotting to restore the Stuarts, finally Royalists plotting against each other on behalf of rival dynasties--an organization of this kind, enabling one to work secretly for a cause and to set invisibly vast numbers of human beings in motion, might prove invaluable to any party.
