At one time the Dionysians referred to themselves as Sons of Solomon, and one of the most important of their symbols was the Seal of Solomon--two interlaced triangles. This motif is frequently seen in conspicuous parts of Mohammedan mosques. The Knights Templars--who were suspected of anything and everything--are believed to have contacted these Dionysiac artificers and to have introduced many of their symbols and doctrines into mediæval Europe. But Freemasonry most of all owes to the Dionysiac cult the great mass of its symbols and rituals which are related to the science of architecture.
