A more thorough explanation:

Definition: Luminare (loo-muh-nair-ee) is a Latin word that means "lamp." In history, it refers to a small lamp or candle that is set burning on a church altar. The maintenance of the lamp was provided by lands and rents. The plural form of luminare is luminaria.

During the Middle Ages, luminaria were commonly used in churches. They were lit to symbolize the light of Christ and were often placed in front of religious icons or statues.

Today, luminaria are still used in some churches during special religious ceremonies or events. For example, during the Christmas season, luminaria may be placed on the altar to represent the light of the world.

Another example of luminaria is the use of small candles in paper bags, which are placed along walkways or driveways during outdoor events. These luminaria create a beautiful and peaceful atmosphere, especially at night.

These examples illustrate how luminaria are used to symbolize light and create a peaceful atmosphere. They are often associated with religious or spiritual events and are used to enhance the overall experience.
