and took his body with them. From Ymir’s body Odin and his brothers created what we know as earth. As Ymir’s blood drained from his body, Odin created oceans and lakes, from his teeth they formed broken bits of rocks and placed them on mountains, from his bones they made boulders, his skull fashioned the sky and respectively his brain formed clouds. After Odin’s creation of earth he sent four dwarves down to each corner of the earth one being Austri meaning east, another called Vestri meaning west, another named Nordri meaning north, and the final one named Sudri meaning south. This is where we get our directions from. Odin and his brothers then set out to make the first people. Odin and his brothers gathered wood from the seashore and created the first people, Ask being the man and Embla being the woman. Light and dark was the final step that Odin had to create. He took Night who is the daughter of a giant that is dark in color. Odin gave Night a chariot pulled by a horse called Hrimfaxi. He instructed Night to ride around the earth and with her she brought darkness, from her horse’s saliva dew was created. He then took Day, the son of Night and Delling of the A''E''sir, who was bright and attractive and gave him a chariot pulled by a horse named Skinfaxi. He instructed Day to ride around the earth and with him he brought light and from his horse’s mane streamed light.

The other gods were angered to hear of Tlaltecuhtli's treatment and decreed that the various parts of her dismembered body would become the features of the new world. Her skin became grasses and small flowers, her hair the trees and herbs, her eyes the springs and wells, her nose the hills and valleys, her shoulders the mountains, and her mouth the caves and rivers.

, there are many gods, but the First Father is called Olorun and he is said to be perfect. Before earth was created there was only sky above and water, swamps, and mist below. One day one of the gods named Olbatala asked Olorun if he could make a world out of what was below. Olorun granted him permission to make a world from the things down below. Before taking action, Obatala consulted with another god named Orunmila (the god of

) who told Obatala to get a golden chain and lower it from the sky to the waters below so that he could eventually return to the other gods. Orunmila also told him to take a snail shell with soil in it, a hen, a black cat, and a palm nut. Obatala heeded the god of divination’s words and descended the golden chain with all of the things he was told to take. Once Obatala reached the waters below he poured all of the soil onto the water. He then set the hen down which spread the soil out by pecking and scratching at it. After the soil was spread, he planted the palm nut which grew and produced more nuts which respectively grew more trees. Obatala thought that this new world needed more light, so he consulted with Olorun who then created the sun and moon and sent fire on a vulture’s head for light when the sun was gone. Obatala got lonely on this new world of his, so he fashioned human beings out of clay and asked the First Father for help. Olorun breathed life into the clay figures and humans became living. Olorun also gave life to animals, plants, rivers, and language for the people to utilize. When Obatala was pleased with his work he climbed back up the golden chain and lived with the other gods in the sky above.
