Zisa was called "Isis Sueborum" or the "Isis of the Suebi". She is thought to be an etymological double of "Teu" or "Ziw", an old Germanic name for Tyr, and is theorized to be his unnamed wife.
Does anyone here have any experience with Zisa? Who is she?
Her name is probably cognate to Juno. Because Tyr is cognate to Jupiter (from archaic Latin Diovis [pater]), and Juno comes from Diovona, and etymological double to Jupiter, and Zisa seems to be an etymological double of Zeu, an old Germanic word for Tyr.
I am going to put in some research here even though I know it might not return much. Some we would only know from personal experiences as there were a great many Gods and Goddesses specific to locations and tribes. The name has a certain thing about it
