Sumerian is an oddball of ancient languages. It might never have been deciphered if not for a happy circumstance I’ll mention below. Other languages important to the history of mythology and religion largely fall into two categories: Into-European (Sanskrit, Old Persian, Greek, Latin) and Semitic (Akkadian, Amorite, Eblaite, Phoenician, Ugaritic, Arabic, Hebrew). But Samuel Noah Kramer says of Sumerian that it “stands alone and unrelated to any known language living or dead” (Sumerian Mythology, 1961, Harper and Row). How did we decipher it, then, and why was it worth the trouble? As to how, we are very fortunate that the Akkadian speaking peoples who followed the Sumerians revered the language and wrote interlinear texts with Akkadian translations of Sumerian compositions. As to why, the answer is simple and profound: the great myths and religious concepts of Mesopotamia, so foundational to numerous later cultures, were born in ancient Sumer.
"A true master does not force the power of the cosmos to their will, but aligns their will with the streams of power that already exist."
— Paternus: War of the Gods, Dyrk Ashton
In a previous phase of my life I was a theologian and led a small congregation. That's why I appreciate the genius of Dyrk Ashton in this sentence. Pratha is explaining the finer concepts of magic and mysticism to Fi and Zeke. They possess astounding abilities to alter the cosmos around them. Elements of many different faiths come into play in Ashton's world, not least Christianity, Buddhism, Hinduism, various polytheisms, and more — including an occasional hat tip to Judaism. But here, we find what many people of faith have discovered, that there is a logos, a pattern of wisdom, a natural law, or whatever you may call it (even perhaps "the will of God" or "the gods"). Best to align with it and, when possible, slightly alter or channel it, than to try remaking it or rendering the pattern null and void. In simple terms, this applies not only to magic but also faith and prayer.
I'm a fantasy fan and I'll bet you are too. I also am in the early stages of building a fantasy world and writing stories and novels. It will be a world like Mesopotamia and my goal is to create something immersive like the best fantasy worlds out there.
