Case studies of archaeoastronomy in Romania

Archaeoastronomy is the discipline which studies celestial phenomena looking from the viewpoint of our ancestors (how they understood and used celestial phenomena and what role the sky played in their cultures). Archaeoastronomy uses different methods, derived from archaeology, anthropology, astronomy, statistics, and probability, in order to determine the thoughts of the ancient civilizations. Because these methods are heterogeneous and use data coming from different sources, the collecting and processing require considerable time. In this article two archaeoastronomical case studies in Romania are presented. First, we show a mathematical method used in order to study the astronomical orientation of the skeletons from the Neolithic necropolis of Cernica. We created a detailed data bank for the Cernica necropolis and, using our program written in MATLAB, we obtained interesting results, mostly from an astronomical point of view. Secondly, we provide an astronomical explanation about the ten radiuses on the top of the Andesite Stone from Sarmizegetusa Regia
