Archaeoastronomy is the “science of stars and stones”. It is an interdisciplinary science in between architecture, archaeology, and astronomy. It studies the relationships between the ancient monuments and the sky, in order to gain a better understanding of the ideas of the architects of the past and of their religious and symbolic world. The course provides the first complete, easy introduction to this fascinating discipline. During the course, many spectacular ancient sites of archaeology – such as Stonehenge in England, Giza and Karnak in Egypt, Chichen Itzá in the Yucatan, Macchu Picchu in Peru and the Pantheon in Rome – will be visited and the fascinating events occurring there in special days of the year (such as solstices, equinoxes, or the day of the foundation of Rome) will be shown and explained. The course also provides the necessary background on Astronomy with the naked eye and a general introduction to the role of Astronomy in religion and in the management of power among ancient cultures.
