The return of the alchemists

Paging H.P. Lovecraft. Mr. Lovecraft to the courtesy phone please. From JayWeidner.com:

In addition to its profound restatement of the Western esoteric tradition,which is significant enough, perhaps the single most important aspect of LeMystere was the single chapter added to the 1957 edition of the book. This chapter, called 'The Cyclic Cross of Hendaye,' discusses a simple yet mysterious monument located in southwestern France that Fulcanelli dates to the middle of the seventeenth century. The monument's few inelegant symbols reveal not only that it was built by a 'master mason,' but also that its creator possessed a surprising amount of arcane knowledge. It also proved,and Fulcanelli echoes this, that there was, and possibly still is, a group of people, a secret society, if you will, that knows the very secret of time and light, which secret is the basis of all true alchemy. More surprisingly, Fulcanelli tells us that this secret society was still active as few as three hundred and fifty years ago. The message of the cross at Hendaye is that time is not a mystery, that the secret of time itself could be understood. Like a river, time has many bends and turns, many tributaries and creeks, but it is possible that time, like a river, can be mapped. And when the map of time is properly understood, the mystery of the future disappears. In addition to this remarkable revelation, the symbols and teachings encoded in the cross at Hendaye offer us a new understanding of the cosmos, especially with regard to the center of the Milky Way Galaxy and its effect on us.

If they are masters of time and space, how do we know they're not active now? I'm just asking. Hat tip to the Daily Grail.
