I do not know if you are familiar with the following document which exists in the Digital Collection of the University of Chicago, and more precisely the Fathom Archive. It is short but very ornate interview by the eminent Professor on Classics and specialized on ancient magic, Christopher Faraone.
The interview is short but still answers some important questions which provide a fast and easy reading and a résumé of his long lasting research and study. Faraone started on his early graduate years to be interest on ancient magic and especially on Latin poems with references to curses and spells. That was in Stanford University in the early 80s. A course for this subject leaded him to write his doctoral theses on ancient magic with supervision by Professor Winkler.
He is stating that magic was common and under continues use by the Greeks regardless of the era. For the Greeks the notion and practice of magic was everywhere and commonly accepted by personal and civic morals. Scholars however, he argues, they continually dating evidence of magic in later or earlier eras from that of the Classical. “They were looking for rationalist Greeks in the evidence from the classical period, and when they found evidence of "irrational" magical ritual they conveniently dated it in such a way that it no longer was evidence for the period that they were looking at.”
The ancient Greek religion was never apart from the chthonic and / or the underworld gods. He stated that scholars believed on an evolution of the ancient Greek religion. An evolution that Athenians as leaders presented the worship of the Olympian Gods – the Sky Gods. However, nowadays “modern scholars have a much more inclusive view of what constitutes Greek religion.”
Modern observers confuse ancient Greek magic with the modern – or the magic which does not relates with the Greek Gods / Goddesses. He stated that, “[a] lot of what we call magic was for the Athenians simply chthonic religion, religious rituals that were connected with Hermes, Hecate, Hades, Persephone, and gods that lived in the ground--gods that were very closely connected with ghosts and the dead.” Magic was interrelated in the everyday life of an Athenian and a Greek. People used magic to communicate, request, win, love and kill. There are evidences of trials were the eradicator was accused for using magic as weapon. Magic, therefore, was “a morally neutral technology”.
From the earliest curse tablets we do not have any evidences that suggest of any professional magicians working from handbooks – as we are familiar from later cases. As it was a custom and well know an individual could practice magic. Faraone gives the example of Plato’s Republic and the Adeimantus, who mentions “that most people believe that if you've done something evil, you can assuage the gods' anger simply by performing the correct sacrifices. In other words, you can bribe the gods and buy them off. The result is, in this case, that someone who has done wrong goes unpunished. Then he says that people also believe that the gods can be persuaded to punish innocent people, and he cites as evidence the fact the people who hang around the doors of the rich and for a fee will cast curses against their enemies.”
Faraone concludes with an idea that says in brief: the Athenians – that can include the rest of the Greeks (?) – were familiar with magic and magical practices which were in use in an everyday basis. Consequently, as an immediate insight by reading the interview, I get the following questions and conclusion: Athenians used magic in everyday basis and mostly for providing the worst of their fellow-citizen. Can we therefore claim that Athens was an evil place in which each citizen cursed his fellow-citizen? Or maybe what we have as evidences which are very limited in numbers are unique cases of men and women who had a different way to conceive polis and fellowship? Professor Faraone did not make clear the fact that magic had no relationship with the Hellenic religious praxis and therefore Greek magic did not exist. Chthonic deities and Gods were in fact worshiped but in a communal way and under the family’s, genos and polis’ regulations and customs. Magic was a practice hidden in the dark concealed in the crave stones a pockets. It was not a ritual or rite, therefore was not a religious praxis.
