Siéhnam the deer was once the terror of the Chorote of Argentina. He would attack at night, seeking out villages after midnight, and kill people by stabbing them with his large antlers. If he found someone sleeping on their back, he would bite their throat. He killed four people every night.
The day came when the Chorote, tired of the losses incurred, asked the shaman for help. “What is it that comes at night?” they asked him.
The shaman woke up just before midnight and heard Siéhnam approaching. “Now I have caught you!” the shaman said. “I thought it was someone else, but it was you. You and I will fight!”
And fight they did, until the shaman threw Siéhnam down and the deer did not come back. The next day the shaman brought the good news to the village. “Now we can sleep peacefully! I believe the one bothering us will not return again”.
