Archaeologia Baltica

In this work we conduct a study of the orientations of 12 megalithic enclosures in the Alentejo (southern Portugal). Some of these sites date back to the sixth or fifth millennia B.C., and so are among the oldest stone enclosures in Europe. The results of the survey show a pattern of easterly (rising) orientations. In particular, we relate our results to previous studies by Michael Hoskin and colleagues, on the orientations of the seven-stone dolmens in this area, which have shown the existence of a possible sun rising orientation custom.

This paper presents a preliminary approach to the problem of royal tomb orientation in ancient Egypt from the early dynastic mausoleums at the necropolis of Umm al Qab to the impressive subterranean chambers of the tombs at the Valley of the Kings (Biban al Muluk). This clearly shows that the correct orientation of the monuments, from the earlier mastabas to the later hypogea, was mandatory and that the sky plays a key role in understanding ancient Egyptian funerary monuments.

As part of the Uppsala University archaeoastronomical project to study the Minoan calendar, we have investigated representative examples of their buildings and found on Philioremos the third example of a peak sanctuary related to sunrise at the summer solstice. This is the nineteenth example of an important Minoan building exactly related to a major yearly event of the lunisolar calendar that was remembered in archaic Greek literature. An important achievement of our project is the discovery of cooperation among Minoans at different sites to mark major celestial events and of well-developed methods for maintaining a seasonally correct lunisolar calendar that began in connection with the autumn equinox.

The relationship between petroglyphs and archaeoastronomy has been treated in several ways in the past. In the present study, we examine a particular motif found among the rock carvings in the north-west of the Iberian Peninsula: a large deer with over-sized horns and an unnatural number of tips on each horn. A multidisciplinary approach combining landscape archaeology, comparative history of religions, and archaeoastronomy suggests a coherent interpretation of the motif. It reveals a unique amalgamation of calendrical motives, landscape relationships and lunisolar events. It may also be significant in relation to the Celtic world-view and its artistic manifestation, and to the relationship between time and landscape.

In this article, some new approaches to Taurapilis prehistoric site, situated in the Utena district in Lithuania, are proposed. As a projection of a taurus horn on the ground in a water form, Lake Tauragnas was the principal factor shaping the particular prehistoric space and determining its status. In this way also, the origins of the Taurapilis Central Place, dated to the fifth or sixth centuries, are explained.
