I just love these cryptic symbols, sigils or seals what H.P. Lovecraft has offered us via his stories.

According to Sumerian mythology, Marduk was the God who defeated the Ancient Ones long before the creation of matter as we know it. Against him in battle were the fierce TIAMAT, KINGU, and AZAG-THOTH. Once he had destroyed these demons, he created the universe from the flesh of TIAMAT, and humanity from the blood of KINGU mixed with his own breath. You will come across these names in the description of the Fifty Names, which were titles given to Marduk by the Elder Gods after he had helped them to defeat the Ancient Ones. This is nothing less than the Biblical story of the war in heaven and the fall of Lucifer; and, in fact, it was recorded by the Sumerians even before there was a Jewish religion, as the Sumerians were the first civilization in the Middle East and their holy books and legends became the basis for much that we read in the Old Testament. The Tower of Babel, for instance, is very probably the Ziggurat (or temple) of Babylon. which was originally a Sumerian city before it was captured by the Assyrian hordes.
