The Dragon's Tail is a modern name for the phantom peninsula in southeast Asia which appeared in medieval Arabian and Renaissance European world maps. It formed the eastern shore of the Great Gulf (Gulf of Thailand) east of the Golden Chersonese (Malay Peninsula), replacing the "unknown lands" which Ptolemy and others had thought surrounded the "Indian Sea".
The peninsula known to modern cartographers as the "Dragon's Tail" or "Tiger's Tail" [1] appeared under various names on different maps.
The peninsula does not appear in any surviving manuscript of Ptolemy's Geography or other Greek geographers. Instead, it is first attested in the Ptolemaic-influenced Book of the Description of the Earth compiled by al-Khwārizmī around 833 AD. Ptolemy's map ended at 180°E of the Fortunate Isles without being able to explain what might lie on the imagined eastern shore of the Indian Ocean or beyond the lands of the Sinae and of Serica in Asia. Chinese Muslims traditionally credit the Companion Saʿd ibn Abi Waqqas with having missionized the country as early as the 7th century; the trading community was large enough that a large-scale massacre is recorded at Yangzhou in 760. [2] [3] Merchants such as Soleiman showed Al-Khwārizmī that the Indian Ocean was not closed as Hipparchus and Ptolemy had held but opened either narrowly or broadly. Al-Khwārizmī left most of Ptolemy's eastern coast but the creation of the strait created a new peninsula, beyond which he placed the Sea of Darkness and the Island of the Jewel. [4] [5]
Bartholomew Dias passed the Cape of Good Hope during a major storm in 1488; within a year or two, Martellus had published a world map showing the communication of the Atlantic and Indian Oceans, creating an unconnected south point of Africa and transforming the eastern end of Ptolemy's shoreline into a great peninsula, similar to that described by Al-Khwārizmī. [6] The area was detailed with locations from Marco Polo and other travelers, including positions formerly related to Ptolemy's Golden Chersonese. [6] A similar peninsula then appeared on the Erdapfel globe drafted by Martin of Bohemia in 1492, just prior to Columbus's return. In the mid-16th century, António Galvão mentioned a map that had been purchased in 1428 by Dom Pedro, eldest son of John I, which described the Cape of Good Hope and included "the Strait of Magellan" under the name "Dragon's Tail" (Portuguese : Cola do dragam). [7] [8] Some South American scholars have taken this at face value as evidence of early and thorough exploration of the Americas, but their claims have not been substantiated. [9] [10]
Christopher Columbus—at least initially—believed in the existence of the peninsula, whose position and attendant islands considerably shortened the expected distance from the African coast to East Asia. [12] He may have been guided directly by Martellus's maps. [13] Columbus considered himself to have arrived at Champa, which figured prominently in three inscriptions on Martellus's 1491 map, and cartographers began to draw discoveries in Central America on the eastern shore of the phantom peninsula. [12] Amerigo Vespucci also considered himself to have arrived at this peninsula rather than a new world. [14]
Another form of this peninsula appeared in the 1502 Cantino planisphere smuggled out of Portugal for the Duke of Ferrara. [15] The map has lost the Great Gulf and the peninsula continues to be too large, but it has merged with the Golden Chersonese as a single landform and bent more towards the east, apparently influenced by Arabic sources. [16]
The Portuguese were aware of the peninsula's likely nonexistence by shortly after the fall of Malacca, when Albuquerque acquired a large Javanese map of Southeast Asia. [17] The original was lost aboard the Froll de la Mar shortly afterwards [18] but a tracing by Francisco Rodrigues was sent in its place as part of a letter to the king. [note 1] Nonetheless, published maps continued to include it in different forms for another century.
The southern end of the peninsula was generally known as the Cape of Cattigara.
Martellus's world maps include labels marking the areas of Upper India (India Superior), Champa (Ciamba Provincia), and Greater Champa (Ciamba Magna Provincia).
The Malay Peninsula is located in Mainland Southeast Asia. The landmass runs approximately north–south, and at its terminus, it is the southernmost point of the Asian continental mainland. The area contains Peninsular Malaysia, Southern Thailand, and the southernmost tip of Myanmar (Kawthaung). The island country of Singapore also has historical and cultural ties with the region.
Muhammad ibn Musa al-Khwarizmi, or simply al-Khwarizmi, was a polymath who produced vastly influential Arabic-language works in mathematics, astronomy, and geography. Around 820 CE, he was appointed as the astronomer and head of the House of Wisdom in Baghdad, the contemporary capital city of the Abbasid Caliphate.
Antillia is a phantom island that was reputed, during the 15th-century age of exploration, to lie in the Atlantic Ocean, far to the west of Portugal and Spain. The island also went by the name of Isle of Seven Cities.
The Ptolemy world map is a map of the world known to Greco-Roman societies in the 2nd century. It is based on the description contained in Ptolemy's book Geography, written c. 150. Based on an inscription in several of the earliest surviving manuscripts, it is traditionally credited to Agathodaemon of Alexandria.
The Fra Mauro map is a map of the world made around 1450 by the Italian (Venetian) cartographer Fra Mauro, which is “considered the greatest memorial of medieval cartography." It is a circular planisphere drawn on parchment and set in a wooden frame that measures over two by two meters. Including Asia, the Indian Ocean, Africa, Europe, and the Atlantic, it is orientated with south at the top. The map is usually on display in the Biblioteca Nazionale Marciana in Venice in Italy.
Niccolò de' Conti was a Venetian merchant, explorer, and writer. Born in Chioggia, he traveled to India and Southeast Asia, and possibly to Southern China, during the early 15th century. He was one of the sources used to create the 1450 Fra Mauro map, which indicated that there was a sea route from Europe around Africa to India.
Dom Peter, Duke of Coimbra, KG was a Portuguese infante (prince) of the House of Aviz, son of King Dom John I of Portugal and his wife, Philippa of Lancaster, daughter of John of Gaunt. In Portugal, he is known as Infante Dom Pedro das Sete Partidas [do Mundo], "of the Seven Parts [of the World]" because of his travels. Possibly the best-travelled prince of his time, he was regent between 1439 and 1448. He was also 1st Lord of Montemor-o-Velho, Aveiro, Tentúgal, Cernache, Pereira, Condeixa and Lousã.
The earliest known world maps date to classical antiquity, the oldest examples of the 6th to 5th centuries BCE still based on the flat Earth paradigm. World maps assuming a spherical Earth first appear in the Hellenistic period. The developments of Greek geography during this time, notably by Eratosthenes and Posidonius culminated in the Roman era, with Ptolemy's world map, which would remain authoritative throughout the Middle Ages. Since Ptolemy, knowledge of the approximate size of the Earth allowed cartographers to estimate the extent of their geographical knowledge, and to indicate parts of the planet known to exist but not yet explored as terra incognita.
The Geography, also known by its Latin names as the Geographia and the Cosmographia, is a gazetteer, an atlas, and a treatise on cartography, compiling the geographical knowledge of the 2nd-century Roman Empire. Originally written by Claudius Ptolemy in Greek at Alexandria around 150 AD, the work was a revision of a now-lost atlas by Marinus of Tyre using additional Roman and Persian gazetteers and new principles. Its translation – Kitab Surat al-Ard – into Arabic by Al-Khwarismi in the 9th century was highly influential on the geographical knowledge and cartographic traditions of the Islamic world. Alongside the works of Islamic scholars – and the commentary containing revised and more accurate data by Alfraganus – Ptolemy's work was subsequently highly influential on Medieval and Renaissance Europe.
The Waldseemüller map or Universalis Cosmographia is a printed wall map of the world by German cartographer Martin Waldseemüller, originally published in April 1507. It is known as the first map to use the name "America". The name America is placed on South America on the main map. As explained in Cosmographiae Introductio, the name was bestowed in honor of the Italian Amerigo Vespucci.
Henricus Martellus Germanus was a German cartographer active in Florence between 1480 and 1496. His surviving cartographic work includes manuscripts of Ptolemy's Geographia, manuscripts of Insularium illustratum, and two world maps which were the first to show a passage around the southern tip of Africa into the Indian Ocean. His world maps summarize geographical knowledge at the outset of the Age of Discovery and "epitomize the best of European cartography at the end of the fifteenth century."
The Erdapfel is a terrestrial globe 51 cm (20 in) in diameter, produced by Martin Behaim from 1490 to 1492. The Erdapfel is the oldest surviving terrestrial globe. It is constructed of a laminated linen ball in two halves, reinforced with wood and overlaid with a map painted on gores by Georg Glockendon. These intricate details were based on navigational charts by Jorge de Aguiar, incorporating paper maps meticulously pasted onto a parchment layer encircling the globe.
The Golden Chersonese or Golden Khersonese, meaning the Golden Peninsula, was the name used for the Malay Peninsula by Greek and Roman geographers in classical antiquity, most famously in Claudius Ptolemy's 2nd-century Geography.
This is a chronology of the early European exploration of Asia.
Medieval Islamic geography and cartography refer to the study of geography and cartography in the Muslim world during the Islamic Golden Age. Muslim scholars made advances to the map-making traditions of earlier cultures, explorers and merchants learned in their travels across the Old World (Afro-Eurasia). Islamic geography had three major fields: exploration and navigation, physical geography, and cartography and mathematical geography. Islamic geography reached its apex with Muhammad al-Idrisi in the 12th century.
Cartographic censorship is the deliberate modification of publicly available maps in order to disguise, remove, or obfuscate potentially strategic locations or buildings, such as military bases, power plants or transmitters. Sensitive objects and places have been removed from maps since historic times, sometimes as a disinformation tactic in times of war, and also to serve competitive political and economic interests, such as during the Age of Discovery when strategic geographic information was highly sought after. In modern times requests for censorship are sent to Google Earth for certain sites that are deemed to pose security risks for national governments.
Lochac, Locach or Locat is a country far south of China mentioned by Marco Polo. The name is widely believed to be a variant of Lo-huk 罗斛: the Cantonese name for the southern Thai kingdom of Lopburi, which was a province of the Khmer Empire at the time.
The Island of the Jewel or Island of Sapphires was a semi-legendary island in medieval Arabic cartography, said to lie in the Sea of Darkness near the equator, forming the eastern limit of the inhabited world.
The Magnus Sinus or Sinus Magnus, also anglicized as the Great Gulf, was the form of the Gulf of Thailand and South China Sea known to Greek, Roman, Arab, Persian, and Renaissance cartographers before the Age of Discovery. It was then briefly conflated with the Pacific Ocean before disappearing from maps.
Cattigara is the name of a major port city located on the Magnus Sinus described by various antiquity sources. Modern scholars have linked Cattigara to the archaeological site of Óc Eo in present-day Vietnam.
