I'll take that as a yes.SandChigger wrote:Leto reigned for 3,500 years. Heretics begins 1,500 years after his death. That's a total of 5,000 years from the beginning of his reign until the beginning of Heretics.
Leto began keeping his journals in the first year of his reign. At some point he learned of the Ixian development of no-tech or they approached him with it as a gift or product for purchase. It could be that the Harkonnens were commissioned the development and he learned of it, or the Harkonnens got wind of the new development and approached the Ixians and Leto allowed the Ixians to sell it to the Harkonnens as well, in order to drain their resources and keep them occupied.
However it played out, Leto had a no-globe/complex built on Arrakis at Dar-es-Balat, "The House of Tiles", and concealed his "Hidden Journals" there, with the Ixian machinery that recorded his thoughts. Above the door to the complex was an inscription saluting the future discoverer thereof as the first person to see his chronicles for four thousand years.
Now, I read this as meaning that the four thousand years refers to the age of the Dar-es-Balat complex. This means the four thousand years fits inside the five-thousand–year period I mentioned at the beginning, with one thousand years leeway which has to be divided between the periods before and after.
We know that Dar-es-Balat is discovered before the beginning of Heretics because the Bene Gesserit know of it and have incorporated some of the contents of the Hidden Journals into their traditions. This would no doubt require a couple hundred years or more. I've never been able to find anything in the texts that would help to pinpoint the exact dates, so I generally just think of Dar-es-Balat as having been built around 500 years into Leto's reign (it would have taken time for the Ixians to develop the no-tech and telepathic recording equipment) and as having been rediscovered about 500 years before the beginning of Heretics (giving the BG time to absorb and integrate the contents).
Just my interpretations and speculations offered as one possibility.
(In Winds the Ixians are already selling methods simulating telepathy [because KJA has to preempt FH with every kewl techy thang he can ... the House books no-tech being the prime example], so no doubt they're going to have Leto building the complex very early in his reign, if not immediately after he ascends to the throne.)
Man, you're thorough.
