3. In medieval Europe, navigation was considered to be part of seven mechanical arts, none of which was used for long voyages open to the sea; Polynesian navigation was probably the earliest form of ocean voyage. it is based on records and observation records in scientific instruments. Early Pacific Polynesians used the motion of stars, the weather, the location of some wildlife species, or the size of the waves to find a path from one island to another. Descriptions of how to make and use marine constellations were first published in 1551 by Spanish cosmologist Melvinmeier and Cespedes's Arte de Navegal, based on the principles of the Egyptian pyramids; in the 15th century, in the Age of Discovery, we began to use star wheels and compasses for ocean navigation. Under the auspices of Prince Henry, the Portuguese began a systematic exploration of the Atlantic coast of Africa in 1418. The first march around the earth was completed in 1522, and the Spanish expedition led by Portuguese explorer Ferdinand Magellan, together with the Magellan Elcano expedition, was completed by the Spanish navigator Juan Sebastian El Cano after his death in the Philippines in 1521.
