Besides ordinary religious manipulation-tools the Egyptians were masters of using architecture for propaganda. In Egypt, most of all, architecture was used as a media to demonstrated power, whereas the Greek and Romans used other types of art, like statues, for political propaganda.
The pyramids, palaces, tombs became tools for power demonstrations. Paintings and carvings (like on obelisks) proved the might of the rulers.
All those signs of power were done to make people compare their ruling dynasty to gods and keep them politically silent, because religion was used for justifying mortal power. Marble, gold, jewelry and artists were the tools for those maneuvers. Whereas questions for the truth were not even asked or listened to.
Finally it was the masses who were used for propaganda, when they were not only forced to work as slaves on those signs of power but also were abused for those power demonstrations, when they had to accompany the dead king into his tomb - dying of hunger, thirst, lack of oxygen and in darkness. The more religious disinformation the more luxury. The more luxury the better. The more luxury the more power.

GCHQ is the British Government Communication Headquarters, which is in fact an electronic monitoring centre which intercepts communications using spy satellites, listening devices and code-cracking equipment. The 1994 Intelligence Services Act defines GCHQ's role in the post Cold War world. National security, economic well-being and the prevention and detection of serious crime are its headline interests. It routinely gathers information on drug-dealing, terrorism, and the movement of arms and key resources such as oil, but is also said to be heavily involved in ECHELON. GCHG praises itself to use and design high end technology such as Cray systems, Tandem based storage and high-end workstations, as well as software for Signals Analysis, Complex Data Manipulation, Translation and Transcription.
