I just got done reading about followers of Dionysus, and at the end there's this mention of Dionysiac Architects. I did a cursory search, but it's the first I've heard of this ancient society.
Dionysus is viewed as a late arriver to Greek Mythology, but an early contender since his mention in Hesiod's work. It is posited he may have roots in Crete. Put 2 and 2 together, if his origin is indeed Crete, and Dionysus predates Ancient Greece, its plausible the Dionysiac Architects are from Minoan Crete.
Dionysos was most certainly not a late arrival in the Greek pantheon: he was a mainland Greek god at least as early as 1250 BCE, which is earlier than most of the other Olympians.
However, prior to the decipherment of Linear B it was widely believed that he was a late arrival, since that is what the classical Greeks themselves believed. Though it has been known for certain since the 1960s that that belief was wrong, the notion continues to hold some traction among people who rely on extremely old secondary sources. Best check whether your source is based on obsolete material like this.
I have never heard of anything like "Dionysiac architects" and my best guess is that there has been a confusion of "Dionysos" with "Daidalos/Daedalus" (since Daidalos was, in a way, associated with Cretan architecture in the classical Greek mind). Even before Linear B was deciphered, Dionysos was believed to be of northern origin (Thrace; definitely not Cretan): that belief was also wrong, but the version you report suggests that your source has badly distorted even that false belief.
