How ancient sailors navigated without maps

Описание: How did ancient sailors cross thousands of miles of open ocean without a single map, compass, or instrument? This is the full story of humanity's greatest navigational achievement — from the Polynesian wayfinders who settled the Pacific using only stars, ocean swells, and birds, to the Arab pilots who turned monsoon winds into trade highways, the Vikings who crossed the North Atlantic with a crystal sunstone, and the Chinese inventors of the compass. A richly narrated history of how every great seafaring civilization on Earth learned to read the sky, the sea, and the wind — and how that knowledge was nearly lost forever. Ideal for sleep, study, or deep relaxation. Over 2 hours of immersive historical storytelling.
