Munsters map of Asia following the model established by Ortelisu's 1567 Asiae Nova Descriptio, this map covers from the Mediterranean to Japan and from the Arctic to Java. Relife is renedered in profile and numerous towns and cities are noted. Sumatra is identified as Taprobana. Japan appears in its kite-form and is based upon Jesuit sources. The great rivers of Southeast Asia, the Mekong, Chao Phraya, Irrawaddy, and Brahmaputra, are drawn as originating from a large lake in the mountains of what is today northern Thailand - no doubt a precursor of the apocryphal lake of Chiamay. The islands of east Indies, collectively identified here as the 'Moluccos,' are vaguely rendered but recognizable.
Asia is Earth's largest and most populous continent, located primarily in the Eastern and Northern Hemispheres. The history of Asia can be seen as the distinct histories of several peripheral coastal regions: East Asia, South Asia, Southeast Asia and the Middle East, linked by the interior mass of the Central Asian steppes. The coastal periphery was home to some of the world's earliest known civilizations, each of them developing around fertile river valleys. The civilizations in Mesopotamia, the Indus Valley and the Yellow River shared many similarities. These civilizations may well have exchanged technologies and ideas such as mathematics and the wheel. Other innovations, such as writing, seem to have been developed individually in each area. Cities, states and empires developed in these lowlands. The central steppe region had long been inhabited by horse-mounted nomads who could reach all areas of Asia from the steppes. The earliest postulated expansion out of the steppe is that of the Indo-Europeans, who spread their languages into the Middle East, South Asia, and the borders of China, where the Tocharians resided. The northernmost part of Asia, including much of Siberia, was largely inaccessible to the steppe nomads, owing to the dense forests, climate and tundra. These areas remained very sparsely populated.The center and the peripheries were mostly kept separated by mountains and deserts. The Caucasus and Himalaya mountains and the Karakum and Gobi deserts formed barriers that the steppe horsemen could cross only with difficulty. While the urban city dwellers were more advanced technologically and socially, in many cases they could do little in a military aspect to defend against the mounted hordes of the steppe. However, the lowlands did not have enough open grasslands to support a large horsebound force; for this and other reasons, the nomads who conquered states in China, India, and the Middle East often found themselves adapting to the local, more affluent societies.
