The Winter Solstice is an astronomical event that marks the shortest day of the year, thus the longest night and the following advent of longer days. Since ancient times, cultures around the world have celebrated this day as a time of rebirth and celebration. The Friends of Serpent Mound have been observing the Winter Solstice with a luminary lighting since 2004. Attendees gather around the prehistoric Serpent Mound snake effigy, which is believed to be aligned with the Winter Solstice sunrise, and light luminaries with tapered candles. The candles are lit from a sacred central fire in homage to Native American ancestors. Starting at 5 p.m., there will be a discussion of Winter Solstice traditions from around the world, followed by the serpent lighting. Bring a flashlight, taper candles and a platter of holiday goodies to share.
