ABSTRACT
OTHER circles too are brought into being, white, spacious, and dense, which enclose the rainbow and its colours, with a dusky circle on the under side, all of which, since they are caused by the reflection of the black clouds and the whiteness of the very thick snow which wholly covers the face of the earth, are chiefly seen in February and March, because of the distant, slanting position of the sun. They maintain effects which differ only slightly from those described above, 1 except that blacker clouds in the lower circle foretell that savager tempests are on the way; and it is of this that the ravenous sea-birds, fleeing from the sea to the fields, seem to have a presentiment and to predict with their unceasing jabber. 2 But these tempests and their like, as was said earlier of the whirlwind, 3 do not last long, for the greater their fury, the shorter their duration.
