This brings us to an alternative theory concerning the channel through which Eastern doctrines, and particularly Cabalism, found their way into Freemasonry. For it must be admitted that one obstacle to the complete acceptance of the theory of the Templar succession exists, namely, that although the Judaic element cannot be traced further back than the Crusades, neither can it with certainty be pronounced to have come into existence during the three centuries that followed after. Indeed, before the publication of Anderson's "Constitutions" in 1723 there is no definite evidence that the Solomonic legend had been incorporated into the ritual of British Masonry. So although the possession of the legend by the _compagnonnages_ of the Middle Ages would tend to prove its antiquity, there is always the possibility that it was introduced by some later body of adepts than the Templars. According to the partisans of a further theory, these adepts were the Rosicrucians. Rosicrucian Origin One of the earliest and most eminent precursors of Freemasonry is said to have been Francis Bacon. As we have already seen, Bacon is recognized to have been a Rosicrucian, and that the secret philosophical doctrine he professed was closely akin to Freemasonry is clearly apparent in his _New Atlantis_. The reference to the "Wise Men of the Society of Solomon's House" cannot be a mere coincidence. The choice of Atlantis--the legendary island supposed to have been submerged by the Atlantic Ocean in the remote past--would suggest that Bacon had some knowledge of a secret tradition descending from the earliest patriarchs of the human race, whom, like the modern writer Le Plongeon, he imagined to have inhabited the Western hemisphere and to have been the predecessors of the Egyptian initiates. Le Plongeon, however, places this early seat of the mysteries still further West than the Atlantic Ocean, in the region of Mayax and Yucatan.[324]
