Why does Santa Claus wear a red coat and pants trimmed with white fur and black boots? Why does Santa come down the chimney and into the house to deliver his gifts? Why do reindeer pull Santa’s sleigh? Why does Santa carry his gifts in a sack? Why does Santa have such rosy cheeks?

There is a saying that behind every myth lies a wee bit of truth. The answer to these questions may be found in pre-Christian rituals practiced in northern Europe at the time of the winter solstice. The collection, preparation, and use of fly agaric mushrooms (Amanita muscaria) were central to many northern European and Asian peoples’ winter solstice celebrations and ceremonies.

In the days leading up to the winter solstice, the fly agaric mushroom appears under trees, mostly firs and spruces. The fly agaric mushroom’s cap is dark red to reddish-orange with creamy-white small patches dotting the cap in an irregular pattern.

In central Asia, shamans wore special garments to collect the fly agaric mushrooms. Their coats and pants were red with the collar and cuffs trimmed with white fur and topped off with black boots. The shaman collected the fly agaric mushrooms in a special sack. After collecting the mushrooms, the shaman would return to his village and enter the yurt (a portable tent dwelling) through the smoke hole on the roof; does this sound familiar?

During the ceremonial ritual, the shaman would consume and share the sacred mushrooms with the participants. The smoke hole was a gateway or portal into the spiritual world where the people would experience many visions. Among the Sami (Laplander) peoples, the hallucinations associated with ingestion of fly agaric gave the sensation of flying in a “spiritual sleigh” pulled by reindeer or horses (i.e., Santa in his sleigh journeying out into the night to give gifts).
