He conducted his forces through a part of Thrace without meeting with any serious resistance, and approached the mountains. The soldiers looked upon the rugged precipices and lofty summits before them with awe. These northern mountains were the seat and throne, in the imaginations of the Greeks and Romans, of old Boreas, the hoary god of the north wind. They conceived of him as dwelling among those cold and stormy summits, and making excursions in winter, carrying with him his vast stores of frost and snow, over the southern valleys and plains. He had wings, a long beard, and white locks, all powdered with flakes of snow. Instead of feet, his body terminated in tails of serpents, which, as he flew along, lashed the air, writhing from under his robes. He was violent and impetuous in temper, rejoicing in the devastation of winter, and in all the sublime phenomena of tempests, cold, and snow. The Greek conception of Boreas made an impression upon the human mind that twenty centuries have not been able to efface. The north wind of winter is personified as Boreas to the present day in the literature of every nation of the Western world.
