Heliacal Phenomena is a parallel to the author’s Eclipses, being another astronomical introduction for Humanists. The aim is that of providing Humanists with a general overview on the importance of heliacal phenomena from the standpoints of history, literature, astronomy. The book is an invitation for students and scholars to consider this subject, as it has been incredibly useful to science, agriculture, people in several ways. The book covers documents dating back to the ancient texts from Babylon, China, Greece, Rome or the Academies and Scientists, up until the present time. That is, from the epochs in which stars were gods, to the modern applications of high speed astronomical photometry. Heliacal Phenomena is useful as a compendium of information, from which to develop further studies.
