Portolan chartPortolan charts are nautical charts, first made in the 13th century in the Mediterranean basin and later expanded to include other regions. The word portolan comes from the Italian portulano, meaning "related to ports or harbors", and which since at least the 17th century designates "a collection of sailing directions". The term “portolan chart” was coined in the 1890s because at the time it was assumed that these maps were related to portolani, medieval or early modern books of sailing directions.
Chinese treasure shipA Chinese treasure ship (, literally "gem ship") is a type of large wooden ship in the fleet of admiral Zheng He, who led seven voyages during the early 15th-century Ming dynasty. The size of the Chinese treasure ship has been a subject of debate with the Chinese records mentioning the size of 44 zhang or 44.4 zhang, which has been interpreted by some as over in length, while others have stated that Zheng He's largest ship was about or less in length. According to the zh (1658), the first voyage consisted of 63 treasure ships crewed by 27,870 men.
Junk (ship)A junk (Chinese: 船, chuán) is a type of Chinese sailing ship with fully battened sails. There are two types of junk in China: northern junk, which developed from Chinese river boats, and southern junk, which developed from Austronesian ships visiting southern Chinese coasts since the 3rd century CE. They continued to evolve in later dynasties and were predominantly used by Chinese traders throughout Southeast Asia. Similar junk sails were also adopted by other East Asian countries, most notably Japan where junks were used as merchant ships to trade goods with China and Southeast Asia.
Age of DiscoveryThe Age of Discovery or the Age of Exploration, part of the early modern period and largely overlapping with the Age of Sail, was a period from approximately the 15th century to the 17th century, during which seafarers from a number of European countries explored, colonized, and conquered regions across the globe. The extensive overseas exploration, particularly the European colonisation of the Americas, with the Spanish and Portuguese at the forefront, later joined by the Dutch, English, and French, marked an increased adoption of colonialism as a government policy in several European states.
Zheng HeZheng He (; 1371–1433 or 1435) was a Chinese mariner, explorer, diplomat, fleet admiral, and court eunuch during China's early Ming dynasty, and often regarded as the greatest admiral in Chinese history. He was originally born as Ma He in a Muslim family and later adopted the surname Zheng conferred by the Yongle Emperor. Commissioned by the Yongle Emperor and later the Xuande Emperor, Zheng commanded seven expeditionary treasure voyages to Southeast Asia, South Asia, West Asia, and East Africa from 1405 to 1433.
Marco PoloMarco Polo (ˈmɑrkoʊ_ˈpoʊloʊ, ˈmaɾko ˈpolo, ˈmarko ˈpɔːlo; 1254 8 January 1324) was an Italian merchant, explorer and writer from the Republic of Venice who travelled through Asia along the Silk Road between 1271 and 1295. His travels are recorded in The Travels of Marco Polo (also known as Book of the Marvels of the World and Il Milione, 1300), a book that described to Europeans the then-mysterious culture and inner workings of the Eastern world, including the wealth and great size of the Mongol Empire and China in the Yuan Dynasty, giving their first comprehensive look into China, Persia, India, Japan and other Asian cities and countries.
High Middle AgesThe High Middle Ages, or high medieval period, was the period of European history that lasted from AD 1000 to 1350. The High Middle Ages were preceded by the Early Middle Ages and were followed by the Late Middle Ages, which ended around AD 1500 (by historiographical convention). Key historical trends of the High Middle Ages include the rapidly increasing population of Europe, which brought about great social and political change from the preceding era, and the Renaissance of the 12th century, including the first developments of rural exodus and urbanization.
