body of beliefs. According to our hypotheses the main point in the alignment of the rondels was the direction of the rising Sun at the moment of its appearance on the horizon on the day when the construction of the rondel started (Pásztor-P. Barna-Roslund 2008). The first step in the building process of a rondel was to point the eastern gate in the direction of which was determined by the actual sunrise (Fig. 7-8). The imaginary radius between the centre point of the rondel and the eastern gate can be considered as the foundation line of the rondel. As usual the western gate was pointed outwards prolonging the foundation line in a radius length in the case of the circular enclosures with four gateways (Fig. 9). The northern and the southern gateways were also stuck out by a similar geometrical method aligning the directions with the help of a perpendicular axis (Fig. 10). Every rite related to foundation or building activity is a rite of passage at the same time, during which a new, domesticated, structured place is born from a non-existent, foreign, wild, and unstructured quality. Foundation of a sacred place/sanctuary is equal to the domestication of the wild world, it is a sort of "Axis mundi", where horizontal and vertical magic lines meet (Eliade 2014, 529-555, Buhály 2006). Thus in the case of the rondels of the Lengyel culture the light of the rising sun can be considered a 'hierophany' orientating the sacred place or rather: the cosmological principle of the orientation. In cases of only a small geographical region, Western-Hungary (also known as Transdanubia) is taken into consideration in contrast with the whole range of the Lengyel culture, the regular pattern in the orientation of the rondels is even more conspicuous. The orientation values not only fall within the section of the horizon where the sun rises, but inside this is concentrated within a narrow range (+/- 5%) (P. Barna et al. 2015. Fig. 10). The near resemblance between the find assemblages of Sormás-Török-földek (P. Barna 2007; 2013) and Sé-Malomi dúló (Károlyi 1983-84, Kalicz 1998), e.g. the two anthropomorphic vessels, also shown in the exhibition (Fig. 18), give an expressive proof of the coevality of both sites. This chronological position is even more strengthened by the same orientation values of the eastern gateways (75° from north) of both Sormás-Török-földek Enclosure No I and the rondel excavated at Sé. This perhaps is a reflection of a strict insistence on a common guiding principle ruling the orientation and foundation ritual of the rondels in a territory which witnessed not only the emergence of the Lengyel culture, but also that of the "rondel idea" simultaneously formed with the culture (Barna-Pásztor 2011). The archaeological and arhcaeoastronomical investigations have revealed several common 47 ~r~~ I
