Cartography is the study and practice of making and using maps. Combining science, aesthetics and technique, cartography builds on the premise that reality can be modeled in ways that communicate spatial information effectively.
Geographical exploration, sometimes considered the default meaning for the more general term exploration, refers to the practice of discovering remote lands and regions of the planet Earth. It is studied by geographers and historians.
The Cantino planisphere or Cantino world map is a manuscript Portuguese world map preserved at the Biblioteca Estense in Modena, Italy. It is named after Alberto Cantino, an agent for the Duke of Ferrara, who successfully smuggled it from Portugal to Italy in 1502. It measures 220 x 105 cm.
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.
The history of geography includes many histories of geography which have differed over time and between different cultural and political groups. In more recent developments, geography has become a distinct academic discipline. 'Geography' derives from the Greek γεωγραφία – geographia, literally "Earth-writing", that is, description or writing about the Earth. The first person to use the word geography was Eratosthenes. However, there is evidence for recognizable practices of geography, such as cartography (map-making), prior to the use of the term.
Indian maritime history begins during the 3rd millennium BCE when inhabitants of the Indus Valley initiated maritime trading contact with Mesopotamia. As per Vedic records, Indian traders and merchants traded with the far east and Arabia. During the Maurya Empire, there was a definite "naval department" to supervise the ships and trade. At the end of 1st century BCE Indian products reached the Romans during the rule of Augustus, and the Roman historian Strabo mentions an increase in Roman trade with India following the Roman annexation of Egypt. As trade between India and the Greco-Roman world increased, spices became the main import from India to the Western world, bypassing silk and other commodities. Indians were present in Alexandria while Christian and Jewish settlers from Rome continued to live in India long after the fall of the Roman Empire, which resulted in Rome's loss of the Red Sea ports, previously used to secure trade with India by the Greco-Roman world since the Ptolemaic dynasty. The Indian commercial connection with Southeast Asia proved vital to the merchants of Arabia and Persia during the 7th–8th century. A study published in 2013 found that some 11 percent of Australian Aboriginal DNA is of Indian origin and suggests these immigrants arrived about 4,000 years ago, possibly at the same time dingoes first arrived in Australia.
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 AD 150, 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 into Arabic 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.
Hellenistic astrology is a tradition of horoscopic astrology that was developed and practiced in the late Hellenistic period in and around the Mediterranean Basin region, especially in Egypt. The texts and technical terminology of this tradition of astrology were largely written in Greek. The tradition originated sometime around the late 2nd or early 1st century BC, and then was practiced until the 6th or 7th century AD. This type of astrology is commonly referred to as "Hellenistic astrology" because it was developed in the late Hellenistic period, although it continued to be practiced for several centuries after the end of what historians usually classify as the Hellenistic era.
The history of cartography refers to the development and consequences of cartography, or mapmaking technology, throughout human history. Maps have been one of the most important human inventions for millennia, allowing humans to explain and navigate their way through the world.
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, particularly the Hellenistic geographers Ptolemy and Marinus of Tyre, combined with what 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.
The cartography of India begins with early charts for navigation and constructional plans for buildings. Indian traditions influenced Tibetan and Islamic traditions, and in turn, were influenced by the British cartographers who solidified modern concepts into India's map making.
The Catalan Atlas is a medieval world map, or mappa mundi, probably created in the late 1370s or the early 1380s, that has been described as the most important map of the Middle Ages in the Catalan language, and as "the zenith of medieval map-work".
A continent is any of several large geographical regions. Continents are generally identified by convention rather than any strict criteria. A continent could be a single landmass or a part of a very large landmass, as in the case of Asia or Europe. Due to this, the number of continents varies; up to seven or as few as four geographical regions are commonly regarded as continents. Most English-speaking countries recognize seven regions as continents. In order from largest to smallest in area, these seven regions are Asia, Africa, North America, South America, Antarctica, Europe, and Australia. Different variations with fewer continents merge some of these regions; examples of this are merging North America and South America into America, Asia and Europe into Eurasia, and Africa, Asia, and Europe into Afro-Eurasia.
Chinese cartography began in the 5th century BC during the Warring States period when cartographers started to make maps of the Earth's surface. Its scope extended beyond China's borders with the expansion of the Chinese Empire under the Han dynasty. By the 11th century during the Song dynasty highly-accurate maps drawn on grids were produced. During the 15th century, the Ming dynasty admiral Zheng He went on a series of voyages to the South China Sea, Indian Ocean, and beyond and maps for areas outside of China were produced, although world maps covering territories known to the Chinese outside of China existed as early as the Tang dynasty.
The Babylonian Map of the World is a Babylonian clay tablet with a schematic map and two inscriptions written in the Akkadian language. Dated to no earlier than the 9th century BC, it includes a brief and partially lost textual description. The tablet describes the oldest known depiction of the known world. Ever since its discovery there have been a variety of divergent views on what it represents in general and about specific features in particular.
The map of Juan de la Cosa is a world map that includes the earliest known representation of the New World and the first depiction of the equator and the Tropic of Cancer on a nautical chart. The map is attributed to the Castilian navigator and cartographer, Juan de la Cosa, and was likely created in 1500.
Cartography throughout the 14th-16th centuries played a significant role in the expansion of the kingdoms of the Iberian Peninsula for a multitude of reasons. Primarily, the maps developed during this period served as navigational tools for maritime folk such as explorers, sailors and navigators. Mostly the expansion of the Crown of Aragon (which included the Kingdom of Aragon, Kingdom of Valencia and Kingdom of Majorca, together with the Principality of Catalonia, all its territories with seashore on the Mediterranean Sea. The Crown of Aragon controlled the routes across the Mediterranean Sea from the Kingdom of Jerusalem to Europe, as part of the commercial-trade route known as the Silk Road.
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 island does not appear in any surviving manuscript of Ptolemy's Geography nor 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. Ptolemy's map ended at 180° E. of the Fortunate Isles without being able to explain what might lay on the imagined eastern shore of the Indian Ocean or beyond the lands of Sinae and Serica in Asia. Roman missions subsequently reached the Han court via Longbian (Hanoi) and Chinese Muslims traditionally credit the founding of their community to the Companion Saʿd ibn Abi Waqqas as early as the 7th century. Muslim merchants such as Soleiman established sizable expatriate communities; a large-scale massacre of Arabs and Persians is recorded at Yangzhou in 760. These connections showed al-Khwārizmī and other Islamic geographers that the Indian Ocean was not closed as Hipparchus and Ptolemy had held but opened either narrowly or broadly.
