Walter Burkert:
Greek Religion: Is perhaps the most often quoted source of information for newcomers to Hellenismos. There is very good reason for this, it is a great overview of ancient religion, practice, and culture of the Greeks. From the superstitions to the theologies of the Greeks and the rituals and holy times of the religion, you will get much out of this book, using it over and over again as you find yourself more immersed in the faith.

Karl Kerenyi:
Karl Kerenyi is, in my experience, beloved among neo-Hellenists because of his enthusiasm for the subject of the mythos, practice and religion of the ancient Greeks. He often refers to these gods as "Our gods" or "our goddess of..." and in these little touches we look into the mind of a man who was apparently touched by the Gods in way that was likely quite rare in his day. His works are sometimes seen as outdated, predating much archaeology and scientific evidence, but the basics of his works are clear and well thought out and, for those of us who believe, not just study for the sake of intellectual curiosity, it is refreshing.

Roberto Calasso
The Marriage of Cadmus and Harmony: Is probably one of the most astounding pieces of work on the mythos of the Greeks I have ever read. I will not say the Mr Calasso attempts to put the stories into continuity, but rather that he uses them to show time, distance, and emotion in a way that makes one feel almost as if one were reading a novel. He seamlessly traverses the epics, the small myths, the little stories, and manages to inform us as to belief and practice as he does so. Throughout this piece you understand how, in the Greek mind, the Gods were once almost as brothers to us, and how that rift between the mortal and the immortal became ever greater through time, and in doing so reminds us of what a mythos does, it explains, and here it does so with beauty and energy.
