That being said, I've come to a place during my research for my book where I've begun to accept that the Gods may manifest themselves under different names to different cultures. The example that is foremost in my mind is that of Athena, Neith, and Anat. Another well-documented parallel is that of Aphrodite and Inanna.
The Greeks believed in syncretism, but I am having trouble seeing how this fits with a hard polytheist world view. Part of me (the researcher) sees Athena as a facet of a very ancient Indo-European owl-and-serpent Goddess, one that shows up in other cultures as very different Goddesses. Lilith is one example. The other (hard polytheist) part of me looks at Lilith and Athena and recognizes that they are extremely different entities.
Should syncretism have a place in my spirituality? How much room does Hellenismos allow for this kind of middling academic polytheism?
