Chap. 40 (40.) — Of the Rising of the Dog-Star
Who is there that does not know that the vapour of the sun is kindled by the rising of the Dog-star? The most powerful effects are felt on the earth from this star. When it rises, the seas are troubled, the wines in our cellars ferment, and stagnant waters are set in motion. There is a wild beast, named by the Egyptians Oryx, which, when the star rises, is said to stand opposite to it, to look steadfastly at it, and then to sneeze, as if it were worshiping it326. There is no doubt that dogs, during the whole of this period, are peculiarly disposed to become rabid327.
