How strange that the first time I learned of the word "Mundi" was not through any religious teaching, but through reading Bethesda Softworks' The Elder Scrolls lore. Up until now, I thought "Mundus" was something that they had completely made up. That's the 21st century for you.
so .. first off, these are not William Blake .. (though it looks very similar) .. these are mystic christian theological moments, "defeating" the false and dangerous (sic) Eastern and Middle-Eastern mystic moments... as a Jungian, it is hard to look at.. there is a well-meaning side to it, but in the modern world, where disparate cultures bump up against each other quite a bit, and in the modern mindset, where the events of death and tragedy are antiseptically hidden, to focus on economy and science.. it is easy to dismiss .. all-in-all, worthwhile if you care to go deeper.. or enjoy the draftsmanship.
