that's where we get into speculation. without wanting to be accused of being too robert gravesy, i will however say that many of the studies on comparative mythography are quite evident in terms of, say, the Mabinogion or the Irish myths being equivalent to some of the Galician ones, as well as traditions and rituals which were alive up to fairly recently (we are talking about our grandmothers' time in an ancestral rural country like Galicia). The subject is certainly fascinating.
