a red hue, the approach of a most violent storm is announced: and if the clouds hang over the face of the sun without surrounding it, they presage wind from the quarter from which they are drifting, and rain as well, if they come from the south. If, at its rising, the sun is surrounded with a circle, wind may be looked for in the quarter in which the circle breaks; but if it disappears equally throughout, it is indicative of fine weather. If the sun at its rising throws out its rays afar through the clouds, and the middle of its disk is clear, there will be rain; and if its rays are seen before it rises, both rain and wind as well. If a white circle is seen round the sun at its setting, there will be a slight storm in the night; but if there is a mist around it, the storm will be more violent. If the sun is pale at sunset, there will be wind, and if there is a dark circle round it, high winds will arise in the quarter in which the circle breaks. CHAP. 79.—PROGNOSTICS DERIVED FROM THE MOON. The prognostics derived from the moon, assert their right to occupy our notice in the second place. In Egypt, attention is paid, more particularly, to the fourth day of the moon. If, when the moon rises, she shines with a pure bright light, it is generally supposed that we shall have fine weather; but if she is red, there will be wind, and if of a swarthy[684] hue, rain. If upon the fifth day of the moon her horns are obtuse, they are always indicative of rain, but if sharp and erect, of wind, and this on the fourth day of the moon more particularly. If her northern horn is pointed and erect, it portends wind; and if it is the lower horn that presents this appearance, the wind will be from the south; if both of them are erect, there will be high winds in the night. If upon the fourth day of the moon she is surrounded by a red circle, it is portentous of wind and rain.
