Everybody knows about the Egyptian, Maya, Aztec, Sumer civilizations. Documentaries and articles keep bringing news of the results of research about these megalythical ancient civilizations, of their unheard of technological achievements.

But very few know about a more mysterious ancient civilization – the Dacians.

Silent and mysterious, the Dacian temples and fortresses, built in precise cosmogonical patterns, defy the passage of time for over ten thousand years.

The Dacians used to build and wall their very mountains as well. Man-carved blocks of rocks weighing over 3 tons in circular walls around the Dacian fortresses or walling the mountains themselves puzzle the scientists. For if an explanation was found on how the Egyptians built their pyramids, there is none on how the Dacians could have transported these huge blocks of stone to the peaks of the mountains, and the mere quantity of materials used in these buildings by far surpasses the Egyptian pyramids.

The greatest achievement and mystery of the ancient Dacian civilization is Sarmisegetuza Regia - that many call "a Time Computer built in Wood and Stone".

Sarmisegetuza Regia is not a temple, is a colossal complex of hundreds of temples, sanctuaries and fortresses spread on an area of around 2,000 square miles. All the mountains around this complex are terraced and walled.

There is then the mystery of the "intelligent mortar" used by the Dacians – a mortar that not only kills bacterias, but in the presence of water it combines with it and forms a greenish "film" that makes it impermeable to water and the unbelievable "alpha pure iron", with a purity of 99.97%, not rusting because it’s finish is formed by 3 layers of magnetite, iron oxide and respectively alumo-sylicates that have their molecules positioned perpendicular in rapport to the other layers. The layers defy scientific explanation, as they couldn’t have solidified as such without a… change in the magnetic poles of the Earth. There are only two other objects in the world made of the same type of iron, and they date of more recent times: the iron pillar of Delhi, India and an iron disc that was discovered in Mongolia.

The Dacian buildings and complexes are positioned following precise geometrical patterns, occult symbols, maps of the skies, and not only, on immense areas. As an example, one of the patterns is the Constellation of the Dragon in a specific aspect referring to the North Star, with occult/religious meaning.

The Sarmisegetusa's main temple axis points to the sunrise of the precise winter solstice.

Archaeologists have identified five structures that were in reality rows of round stone "lobes" shaped to form short cylinders, neatly arranged within rectangles formed by sides made of small stones cut to a precise design. The two larger of these rectangular structures contained sixty lobes each, one (the "large old sanctuary") in four rows of fifteen, and the other (the "large new sanctuary") six rows of ten. Three components of this ancient "calendar city" were round. The smallest is a stone disk made of ten segments in which small stones were embedded to form a circumference - six stones per segment, making a total of sixty.

The second round structure, sometimes called the "small round sanctuary," consists of a perfect circle of stones, all precisely and identically shaped, arranged in eleven groups of eight, one of seven and one of six; wider and differently shaped stones, thirteen in number, were placed so as to separate the other grouped stones. There must have been other posts or pillars within the circle, for observation and computing; but none can be determined with certainty.

Studies, such as Il Templo-Calendario Dacico di Sarmizegetusa by Hadrian Daicoviciu, suggest that this structure served as a lunar-solar calendar enabling a variety of calculations and forecasts, including the proper intercalation between the solar and lunar years by the periodic addition of a thirteenth month.

The most impressive and intriguing component of this Calendar City is the third round "temple." It consists of two concentric circles surrounding a "horseshoe" in the middle (Fig. 168), bearing an uncanny similarity to Stonehenge in Britain. The outer circle, some 96 feet in diameter, is made up of a ring of 104 dressed andesite blocks that surrounds 180 perfectly shaped oblong andesite blocks, each with a square peg on top as though all were intended to support a movable marker.

These uprights are arranged in groups of six; the groups are separated by perfectly shaped horizontal stones, thirty in all. Altogether, then, the outer circle of 104 stones rings an inner circle of 210 (180 + 30) stones. The second circle, between the outer one and the horseshoe, consists of sixty-eight postholes - akin to the Aubrey holes at Stonehenge - divided into four groups separated by horizontal stone blocks: three each in the northeast and southeast positions and four each in the northwest and southeast positions, giving the "henge" its main northwest-southeast axis and its perpendicular northeast - southwest one.

The innermost "horseshoe"; it consists of an elliptical arrangement of twenty-one postholes, separated by two horizontal stones on each side from a locking line of thirteen postholes that face to the southeast, leaving no doubt that the principal observational target was the winter solstice Sun. H. Daicoviciu, eliminating some of the wooden posts for simpler visualization, offered a drawing of how the "temple" might have looked.

 Noting that the wooden posts were coated with a terra-cotta "plating," Serban Bobancu and other researchers at the National Academy of Romania (Calendrul de la Sarmizegetusa Regia) observed that each of those posts "had a massive limestone block as its foundation, a fact that undoubtedly reveals the numerical structure of the sanctuary and proves, as in fact all the others structures do, that the builders wished these structures to last throughout centuries and millennia."

The latest researchers concluded that the "old temple" originally consisted of only fifty-two lobes (4x13 rather than the 4 x 15 arrangement) and that there were in effect two calendrical systems geared into one another at Sarmizegetusa: one a solar-lunar calendar, and another "ritual calendar" geared to fifty-two weeks, akin to the sacred cycle of Mesoamerica and having stellar aspects rather than lunar-solar ones.

They concluded that the "stellar era" consisted of four periods of 520 years each (double the 260 of the Mesoamerican Sacred Calendar), and that the ultimate purpose of the calendrical complex was to measure an "era" of 2,080 years (4 x 520)- - the approximate length of the Age of Aries.

"Deceneus teaching them Logics...demonstrates to them the theory of the zodiac and showed them the path of the planets and all astronomic secrets, the way the orbit of the Moon increases and decreases, and talked to them about the behaviour of the 346 stars during the quick passage from east to west, going nearer of farther from the celestial pole"
