Celtic Mythology is complex because there are different versions of it based on which Celt you are referring to. There are Gauls, Irish Gaelic, Welsh, Scottish Gaelic, and Celtic-Iberian gods and goddesses. Each group has their own names and differences, but most are really the same in each Celtic culture to another Celtic culture. For purposes of Celtic Mythology analysis, I will probably stick mostly with the Irish Gaelic mythology.
The Irish goddesses were often shown with spirals and triple moon symbolism (a symbol of the Greek Goddess Hecate). There are a few books regarding Irish mythology but they have been corrupted with Christian theosophy and so careful analysis must be made when using sources such as The Irish Mythological Cycle and Celtic Mythology and The Book of Kells.
The Dagda is the "all father" god of the Celts and his description appears to match that of Zeus; however, there are many variations in his story that must be examined. In the next several blog articles, I will attempt to show that many of the Celtic gods are the same as the Greek Gods which are the Cronides. I am not the only one who has noted this similarity between Celtic and Greek-Roman mythology. Julius Caesar also noted it and wrote about it.
