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.
Theatrum Orbis Terrarum is considered to be the first true modern atlas. Written by Abraham Ortelius, strongly encouraged by Gillis Hooftman and originally printed on 20 May 1570 in Antwerp, it consisted of a collection of uniform map sheets and supporting text bound to form a book for which copper printing plates were specifically engraved. The Ortelius atlas is sometimes referred to as the summary of sixteenth-century cartography. The publication of the Theatrum Orbis Terrarum (1570) is often considered as the official beginning of the Golden Age of Netherlandish cartography.
A mappa mundi is any medieval European map of the world. Such maps range in size and complexity from simple schematic maps 25 millimetres or less across to elaborate wall maps, the largest of which to survive to modern times, the Ebstorf map, was around 3.5 m in diameter. The term derives from the Medieval Latin words mappa and mundus (world).
A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth. While this is true of any map, these distortions reach extremes in a world map. Many techniques have been developed to present world maps that address diverse technical and aesthetic goals.
A T and O map or O–T or T–O map, also known as an Isidoran map, is a type of early world map that represents world geography as first described by the 7th-century scholar Isidore of Seville (c. 560–636) in his De Natura Rerum and later his Etymologiae (c. 625)
Terra incognita or terra ignota is a term used in cartography for regions that have not been mapped or documented. The expression is believed to be first seen in Ptolemy's Geography c. 150. The term was reintroduced in the 15th century from the rediscovery of Ptolemy's work during the Age of Discovery. The equivalent on French maps would be terres inconnues, and some English maps may show Parts Unknown.
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.
"Here be dragons" means dangerous or unexplored territories, in imitation of a medieval practice of putting illustrations of dragons, sea monsters and other mythological creatures on uncharted areas of maps where potential dangers were thought to exist.
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 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.
Portolan 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 portolano, meaning "related to ports or harbors", and which since at least the 17th century designates "a collection of sailing directions".
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.
The Beatus map or Beatine map is one of the most significant cartographic works of the European Early Middle Ages. It was originally drawn by the Spanish monk Beatus of Liébana, based on the accounts given by Isidore of Seville, Ptolemy and the Hebrew Bible. Although the original manuscript is lost, there remain several copies extant, which retain a high fidelity with respect to the original.
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 cartography of Asia can refer to the representation of Asia on a map, or to depictions of the world by cartographers from Asia. Depictions of portions of Asia have existed on maps as early as the 6th century BCE, with maps being drafted to depict the Babylonian, Hellenistic Greek, and Han dynasty empires.
"Majorcan cartographic school" is the term coined by historians to refer to the collection of predominantly Jewish cartographers, cosmographers and navigational instrument-makers and some Christian associates that flourished in Majorca in the 13th, 14th and 15th centuries until the expulsion of the Jews. The label is usually inclusive of those who worked in Catalonia. The Majorcan school is frequently contrasted with the contemporary Italian cartography school.
Leonid S. Chekin is a Russian born writer and translator living and working in the United States. He is the author of "Northern Eurasia in Medieval Cartography", from Brepols (2006) a guide to 198 Western European and Byzantine maps from between the eighth and ninth centuries. The volume was first issued in Russia in 1998 as "Kartografia Khrisitianskogo Srednevekovia" In her review of the volume in Cambridge University Press Journal, Speculum:A Journal of Medieval Studies, Natalia Lozovsky states..."The author defines his focus as the lands that medieval Western Europeans and Byzantines, following the Greco-Roman tradition, perceived as the edges of the known world".....
The V-in-squaremap is a highly schematic type of mappa mundi in use in Europe during the Middle Ages. It is based on and usually found in conjunction with the Etymologiae of Isidore of Seville.
