    Getting Hitched
    The Intihuatana Stone is an ancient sundial located in Machu Picchu, Peru, part of the Incan Empire. Incans lived in Machu Picchu until the 1500s and 1600s.

    Incan worshippers might have believed the sun was tethered to the Intihuatana Stone as if on a leash, resulting in the tall stone's nickname: the Hitching Post of the Sun. The stone was arranged to point directly at the sun during the winter solstice. At noon during the equinoxes (where day and night are of equal length), the Intihuatana Stone casts no shadow.

    Solstices now mark the beginning of summer and winter. Because someancient Europeancultures only recognized these twoseasons (there was no autumn or spring), the solstices occurred in the middle of the season. Solstices are known asmidsummer andmidwinter for this reason.

    The summer solstice is the longest day of the year, meaning it has the most hours of sunlight. The winter solstice is the shortest day of the year and has the fewest hours of daylight.

    Solstices happen due to the way the Earth circles, or orbits, the sun. The Earth is tilted on its axis, not straight up-and-down. When the Earth orbits the sun, one half of the Earth is tilted toward the sun, while the other half is tilted away from the sun.. The Earths tilt changes throughout the year, causing the latitude, or location, where the sun appears directly overhead at noon to change also.

    Around June 22, the Earths Northern Hemisphere is tilted toward the sun. The suns vertical rays strike the Tropic of Cancer, 23.5 degrees north of the Equator. The June solstice is the longest day of the year in the Northern Hemisphere (the summer solstice) and the shortest day of the year in the Southern Hemisphere (the winter solstice.)

    The opposite occurs on December 22, when the Earths Southern Hemisphere is tilted toward the sun. The suns vertical rays strike the Tropic of Capricorn, 23.5 degrees south of the Equator. The December solstice is the shortest day of the year (winter solstice) in the Northern Hemisphere and the longest day of the year (summer solstice) in the Southern Hemisphere.

    Since ancient times, many cultures have marked the solstices as the longest and shortest days of the year.

    Ancient European tribes celebrated midsummer with feasts and bonfires. Many of these traditions still survive in Europe and countries that have large populations of European (especially Scandinavian) heritage, such as Canada and the United States. In 1595, the English writer William Shakespeare wrote a comic play called A Midsummer Nights Dream. The play tells the story of two sets of couples enchanted by a magical forest during the summer solstice. Brazil celebrates midsummer with St. John festivals. (Many Christian countries associate midsummer with the birthday of St. John the Baptist. John is a saint, or holy man, to Christians.) Brazils St. John celebrations are among the largest outdoor parties in the world.

    Followers of ancient traditions also honor the winter solstice. Monuments to this event can be seen at Stonehenge, in the United Kingdom, and the so-called Intihuatana Stone, or Hitching Post of the Sun at the Incan ruin of Machu Picchu in Peru. At these sites, people gathered to celebrate and pray for their survival through the winter. Religious holidays surrounded midwinter as well. In the Roman Empire, the midwinter festival (Saturnalia) was celebrated the week of December 25. Early Christians adopted the timing of the holiday for one of their most important holidays, Christmas. Pagans and neopagans, followers of early European religious traditions, still celebrate the winter solstice as a holiday called Yule.
