Tengeriin Odor

The longest night of the year is celebrated with the lighting of candles and fires, and the tradition of staying up all night to watch the stars. The Mongolian winter solstice is one of the coldest nights on earth (temperatures can drop to minus 40 degrees Celsius on the steppe), and the herders bring their animals into the shelter of the winter camp (the uvs, or winter pasture). The night is also a time for storytelling, and the elders tell the epic tales of the Jangar (the Kalmyk-Mongol epic), the Geser (the Tibetan-Mongol epic), and the Secret History of the Mongols. The solstice is a reminder that the light will return, and that the Mongolians have survived the harshest winters on earth for thousands of years.
