Heliacal phenomena. An astronomical introduction for humanistists - De Mei...

Heliacal Phenomena is a parallel to Salvo De Meis’ Eclipses, being another astronomical introduction for Humanists. In such an extremely wide field, both for theoretical aspects and for the number of documents that have accumulated within centuries, the essentials of theory and documentation have been carefully chosen and the events have been recomputed and compared to previous research. The aim is at giving to Humanists a general view on the importance of these phenomena from the points of view of history, literature, astronomy, that in the past were diffused in histories, poems, and treatises now often unavailable. It is an invitation to students and scholars to consider this subject, that was so useful to science, agriculture, peoples, for its many uses, from knowing the seasons of seeding to navigation, the aspect of the sky related to them, and the legacy left to humanity by the ancient texts from Babylon, China, Greece, Rome or the Academies and Scientists until the present time.
