Boreas, the powerful and cold north wind (shown here, compare with photo of marble clock tower), is dressed in warm clothes and holds a triton shell. Without modern navigational equipment, ancient seafarers found their way by observing nature. They tracked the sun and stars, and they learned to know the winds, such as the cold, wet north wind (Boreas) and the hot, dry south wind (Notos).
