Eternal flame


An eternal flame is a flame, lamp or torch that burns continuously for an indefinite period. Most eternal flames are ignited and tended intentionally, but some are natural phenomena caused by natural gas leaks, peat fires and coal seam fires, all of which can be initially ignited by lightning, piezoelectricity or human activity, some of which have burned for thousands of years.

In ancient times, human-tended eternal flames were fueled by wood or olive oil; modern examples usually use a piped supply of propane or natural gas. Human-created eternal flames most often commemorate a person or event of national significance, serve as a symbol of an enduring nature such as a religious belief, or a reminder of commitment to a common goal, such as diplomacy.

The eternal fire is a long-standing tradition in many cultures and religions. In ancient Iran the atar was tended by a dedicated priest and represented the concept of "divine sparks" or Amesha Spenta, as understood in Zoroastrianism. Period sources indicate that three "great fires" existed in the Achaemenid era of Persian history, which are collectively considered the earliest reference to the practice of creating ever-burning community fires.

The eternal flame was a component of the Jewish religious rituals performed in the Tabernacle and later in the Temple in Jerusalem, where a commandment required a fire to burn continuously upon the Outer Altar. Modern Judaism continues a similar tradition by having a sanctuary lamp, the ner tamid, always lit above the ark in the synagogue. After World War II, such flames gained further meaning, as a reminder of the six million Jews killed in the Holocaust.
