Atlas in the context of "Theatrum Orbis Terrarum"

Abraham Ortelius (/ɔːrˈtiːliəs/ or-TEE-lee-əs; also Ortels, Orthellius or Wortels; 4 or 14 April 1527 – 28 June 1598) was a cartographer, geographer, and cosmographer from Antwerp in the Spanish Netherlands. He is recognized as the creator of the first modern atlas, the Theatrum Orbis Terrarum (Theatre of the World). Along with Gemma Frisius and Gerardus Mercator, Ortelius is generally considered one of the founders of the Netherlandish school of cartography and geography. He was a notable figure of this school in its golden age (approximately 1570s–1670s) and an important geographer of Spain during the age of discovery. The publication of his atlas in 1570 is often considered as the official beginning of the Golden Age of Netherlandish cartography. He was the first person proposing that the continents were joined before drifting to their present positions.

The Atlas Maior is the final version of Joan Blaeu's atlas, published in Amsterdam between 1662 and 1672, in Latin (11 volumes), French (12 volumes), Dutch (9 volumes), German (10 volumes) and Spanish (10 volumes), containing 594 maps and around 3,000 pages of text. It was the largest and most expensive book published in the seventeenth century. Earlier, much smaller versions, titled Theatrum Orbis Terrarum, sive, Atlas Novus, were published from 1634 onwards. Like Abraham Ortelius's Theatrum Orbis Terrarum (1570), the Atlas Maior is widely considered a masterpiece of the Golden Age of Dutch/Netherlandish cartography (approximately 1570s–1670s).

The history of astronomy focuses on the efforts of civilizations to understand the universe beyond earth's atmosphere.Astronomy is one of the oldest natural sciences, achieving a high level of success in the second half of the first millennium. Astronomy has origins in the religious, mythological, cosmological, calendrical, and astrological beliefs and practices of prehistory. Early astronomical records date back to the Babylonians around 1000 BC. There is also astronomical evidence of interest from early Chinese, Central American and North European cultures.

Astronomy was used by early cultures for timekeeping, navigation, spiritual and religious practices, and agricultural planning. Ancient astronomers observed and charted the skies in an effort to learn about the workings of the universe. During the Renaissance Period, revolutionary ideas emerged about astronomy. One such idea was contributed in 1543 by Polish astronomer Nicolaus Copernicus, who developed a heliocentric model that depicted the planets orbiting the sun. This was the start of the Copernican Revolution, with the invention of the telescope in 1608 playing a key part. Later developments included the reflecting telescope, astronomical photography, astronomical spectroscopy, radio telescopes, cosmic ray astronomy, infrared telescopes, space telescopes,ultraviolet astronomy, X-ray astronomy, gamma-ray astronomy, space probes, neutrino astronomy, and gravitational-wave astronomy.

This is a list of notable atlases, each a collection of maps, some including statistical data for the regions represented:

Gerardus Mercator (/dʒəˈrɑːrdəs mɜːrˈkeɪtər, mər-/; 5 March 1512 – 2 December 1594) was a Flemish geographer, cosmographer and cartographer. He is most renowned for creating the 1569 world map based on a new projection which represented sailing courses of constant bearing (rhumb lines) as straight lines—an innovation that is still employed in nautical charts.

Mercator was a notable maker of globes and scientific instruments. In addition, he had interests in theology, philosophy, history, mathematics, and geomagnetism. He was also an accomplished engraver and calligrapher. Unlike other great scholars of the age, he travelled little and his knowledge of geography came from his library of over a thousand books and maps, from his visitors and from his vast correspondence (in six languages) with other scholars, statesmen, travellers, merchants and seamen. Mercator's early maps were in large formats suitable for wall mounting but in the second half of his life, he produced over 100 new regional maps in a smaller format suitable for binding into his Atlas of 1595. This was the first appearance of the word Atlas in reference to a book of maps. However, Mercator used it as a neologism for a treatise (Cosmologia) on the creation, history and description of the universe, not simply a collection of maps. He chose the word as a commemoration of the Titan Atlas, "King of Mauretania", whom he considered to be the first great geographer.

A gazetteer is a geographical dictionary or directory used in conjunction with a map or atlas. It typically contains information concerning the geographical makeup, social statistics and physical features of a country, region, or continent. Content of a gazetteer can include a subject's location, dimensions of peaks and waterways, population, gross domestic product and literacy rate. This information is generally divided into topics with entries listed in alphabetical order.

Ancient Greek gazetteers are known to have existed since the Hellenistic era. The first known Chinese gazetteer was released by the first century, and with the age of print media in China by the ninth century, the Chinese gentry became invested in producing gazetteers for their local areas as a source of information as well as local pride. The geographer Stephanus of Byzantium wrote a geographical dictionary (which currently has missing parts) in the sixth century which influenced later European compilers. Modern gazetteers can be found in reference sections of most libraries as well as on the internet.
