Definition: The word "aerodyne" appears in the Old Testament as a term for a kindling fire made by a man who had been instructed to burn a large pile of straw on the hearth to set it alight. This fire was not the standard fire that we know today, but rather an ancient pagan fire source. The concept behind "aerodyne" is rooted in the idea of having light or heat emitted from small particles suspended in air. In this context, a fire made by a man who had been instructed to burn a large pile of straw was seen as an indication that he had ignited some sort of incendiary fuel. This ancient pagan tradition continues to be used in religious and cultural contexts today, often associated with the practice of making fire with small particles suspended in air or burning grains.
