In a world made of stories, past, present, and future are threads woven into the same plot. In a world made of stories, like this one....
One time, long ago, the gods were hungry. None of them had enough and all sixteen felt the constant grumble in their bellies. Their wandering children on the earth, the humans, neglected them. They made little sacrifice and did not feed the gods enough. Some of the gods tried hunting and fishing. They caught one antelope and one fish and these did not last long. Tempers got short. The gods wondered how they might get sustenance from the humans again.
Shango the god of thunder sent down lightening bolts and pelted the earth with meteorites and the humans were afraid but they did not turn to the gods. They rebuilt their houses, some moved to caves. They did not make sacrifices of meat or fish, they did not pour out oil or palm wine, they did not leave feathers or beads or cowrie shells.
Next Olokun, god of the sea, caused great tidal waves and storms. Iku, god of death, came down and took many people. The human children suffered but they still did not remember the gods. They did not make sacrifices of roasted goat and fowl and yams, they did not leave sweets, they did not pour out palm wine.
The situation in heaven was getting desperate. Yemoja, the great mother, went to Eshu and asked him to get involved. "This is a problem that only you can solve," she said, and Eshu agreed. He traveled all around, up and down between heaven and earth every day, and he knew many things because he could talk to everyone. Yemoja told him, "Threatening them doesn't seem to work. We've pounded and pelted them and killed quite a few but they still don't sacrifice. You have to give human beings something good, something really good."
Eshu had an idea but he needed help. He went to his friend Ifa, god of wisdom. Ifa said, "I know why you're here. We need to give something good to the humans and I know just the thing. We can make it from sixteen palm nuts. You have to go to Orungan's garden and get them. Get the nuts and their meaning."
Orungan was a powerful god and his palm trees were full of monkeys, who jealously guarded the nuts. Eshu thought about climbing up into the trees but the trunks were too smooth. So he sat down on the ground and yelled up at them, "Hey you nit-picking airheads, you mindless chatterers," and other insulting things and the angry monkeys threw a few nuts down at him. But monkeys are clever too and they soon stopped. Eshu switched to cajoling and flattery and we don't know what all he said, but the monkeys eventually gave him all sixteen of the desired nuts, though not without a grudge. "You got these nuts through guile Eshu, "the monkeys told him, "so we won't tell you what they mean. We will give you a piece of advice though. Consult with each of the sixteen gods."
Eshu had half of the big, great gift for humankind. Now he had to get the rest.
Eshu took the sixteen palm nuts and he went to each of the sixteen gods. He asked each one to tell him the meaning of each of the sixteen nuts. Some of the gods were reluctant to share all they knew but Eshu was persistent and they were hungry. When Eshu was done he had 256 sayings (that's 16 times 16), a lot of divine wisdom. He took the nuts and their meanings to Ifa, and Ifa came up with the system of divination that bears his name.
Eshu went down to earth and explained Ifa's system, the nuts and their meanings, to the humans. "Now you can know the will of the gods," he told them, "and act on your own behalf. You can see evil coming and avoid it. You can call on the gods for help. But in exchange for these powers, you must sacrifice to the gods, you must feed them." The humans thought this was a great deal. The commerce between heaven and earth now moved along a two-way street and the humans were happy to sacrifice once again. They roasted goat and fowl and fish and yams, they left sweets, they gladly poured oil and shared feathers and beads and cowrie shells. They poured big glasses of palm wine.
The sixteen gods were fed. Everyone was satisfied. As for Eshu, he receives the first portion of every sacrifice because he solved the problems of heaven and earth.
