Apart from the obvious mythological motives used by the artist (Vsevolod Ivanov), the reconstruction is fairly accurate and resembles the more „professional reconstructions” made by archeologists:

• Trypillia reconstruction

• Trypillia and the shape of its houses

The Cucuteni-Trypillian culture is a Neolithic–Eneolithic archaeological culture (c. 5200 to 3500 BC) in Eastern Europe. It extends from the Carpathian Mountains to the Dniester and Dnieper regions, centered on modern-day Moldova and covering substantial parts of western Ukraine and northeastern Romania, encompassing an area of 350,000 km2 (140,000 sq mi), with a diameter of 500 km (300 mi; roughly from Kyiv in the northeast to Brașov in the southwest).

The majority of Cucuteni-Trypillian settlements consisted of high-density, small settlements (spaced 3 to 4 kilometers apart), concentrated mainly in the Siret, Prut, and Dniester river valleys. During the Middle Trypillia phase (c. 4000 to 3500 BC), populations belonging to the Cucuteni-Trypillian culture built the largest settlements in Neolithic Europe, some of which contained as many as 3,000 structures and were possibly inhabited by 20,000 to 46,000 people.

One of the most notable aspects of this culture was the periodic destruction of settlements, with each single-habitation site having a lifetime of roughly 60 to 80 years. The purpose of burning these settlements is a subject of debate among scholars; some of the settlements were reconstructed several times on top of earlier habitational levels, preserving the shape and the orientation of the older buildings. One particular location, the Poduri site in Romania, revealed thirteen habitation levels that were constructed on top of each other over many years. Some scholars have theorized that the inhabitants of these settlements believed that every house symbolized an organic, almost living, entity. Each house, including its ceramic vases, ovens, figurines and innumerable objects made of perishable materials, shared the same circle of life, and all of the buildings in the settlement were physically linked together as a larger symbolic entity. As with living beings, the settlements may have been seen as also having a life cycle of death and rebirth.

Throughout the 2,750 years of its existence, the Cucuteni-Trypillian culture was fairly stable and static; however, there were changes that took place. Members of the Cucuteni-Trypillian culture shared common features with other Neolithic societies, including: an almost nonexistent social stratification, lack of a political elite, rudimentary economy, most likely a subsistence or gift economy, pastoralists and subsistence farmers.

Like other Neolithic societies, the Cucuteni-Trypillian culture had almost no division of labor. Although this culture’s settlements sometimes grew to become the largest on Earth at the time (up to 15,000 people in the largest), there is no evidence that has been discovered of labor specialization. Every household probably had members of the extended family who would work in the fields to raise crops, go to the woods to hunt game and bring back firewood, work by the river to bring back clay or fish, and all of the other duties that would be needed to survive. Contrary to popular belief, the Neolithic people experienced considerable abundance of food and other resources. Since every household was almost entirely self-sufficient, there was very little need for trade. However, there were certain mineral resources that, because of limitations due to distance and prevalence, did form the rudimentary foundation for a trade network that towards the end of the culture began to develop into a more complex system, as is attested to by an increasing number of artifacts from other cultures that have been dated to the latter period.

The Cucuteni-Trypillian culture is known by its distinctive settlements, architecture, intricately decorated pottery and anthropomorphic and zoomorphic figurines, which are preserved in archaeological remains. At its peak it was one of the most technologically advanced societies in the world at the time, developing new techniques for ceramic production, housing building and agriculture, and producing woven textiles (although these have not survived and are known indirectly).
