A possible role of Alpha Crucis in the astronomical landscape of Silbury Hill

Abstract

The paper is discussing a possible link between the construction of Silbury Hill, the prehistoric artificial mound near Avebury, and the observation of Alpha Crucis, the main star of the Crux constellation, which was slowly disappearing from the local sky due to the precession of the Earth's axis. For the discussion, we use simulations of the local astronomical landscape made by means of Stellarium software.
