   • 1903, Edgar MacCulloch, “Proverbs, Weather Sayings, etc.”, in Guernsey Folk Lore‎^[1], page 534:

     Si le soleil est rouage au sèr, / Ch'est pour biau temps aver, / S'il est rouage au matin, / Ch'est la mare au chemin.

     If the sun sets red, it is a sign of fine weather, but when he rises red, you may expect pools of water on the road.
