Halo.
The larger the halo about the moon the nearer the rain clouds and the sooner the rain may be expected.
A lunar halo indicates rain, and the number of stars inclosed, the number of days of rain.
The moon with a circle brings water in her beak.
Horns of Moon.
When Luna first her scattered fear recalls,
If with blunt horns she holds the dusky air,
Seamen and swain predict abundant showers.
(Virgil.)
Moon-shield.
