A form of divination in ancient times involving the observation of smoke and consisting of two principal methods. The more important was the smoke of sacrifices, which augured well if it rose lightly from the altar and ascended straight to the clouds, but the contrary if it hung about. Another method was to throw a few jasmine or poppy seeds upon burning coals. There was also a third method involving breathing the smoke of the sacrificial fire.
