Anemoscopy
AnemoscopyDivination by means of the study of winds. This type of divination involves the observation of wind direction and strength, including the shape of dust clouds lifted by it.A different method is posing a question and then tossing a handful of dirt, sand or light seeds into the air; the answer comes in the form of the small dust cloud made by the flying particles. Another process uses a pendulum, allowed to move only by the wind, positioned over a circle graph or a set of letters, glyphs or runes. Yet another technique consists of listening to the sound of the wind and interpreting its message. Many people hear 'whispers in the wind' as the movement of sound carries voices that we sometimes can here.
Many indigenous people practiced wind scrying as a means of talking to their gods and receiving messages. They believed in wind spirits.
Ancient Greeks practiced wind scrying in the sacred grove of Dodona, which was dedicated to their main god Zeus. Psellus referred to this technique writing "there is a mode of predicting by means of the air and the leaves of the trees. The method involved the hanging of striking wands from branches of sacred oak trees in a way that they struck resounding brass basins when the wind blew. Interpretations were made of these sounds and that of the wind. On a windy day, if one stood still, they could hear tones or perhaps 'whispers in the wind' of the trees as the moving air carries sound vibration.
Native Americans, to this very day, use wind scrying to communicate with spirits.
