Eromanty is one of the six kinds of divination practiced by the Persians by the means of air. They enveloped their heads in a napkin and exposed to the air a vase filled with water, over which they recited in a low voice the objects of their desires. If bubbles appeared on the surface of the water it was regarded as a happy prognostication. (see Eromancy) A.G.H.
