History

The first book that in hindsight could be called an atlas that was constructed from the calculations of Claudius Ptolemy, a geographer working in Alexandria circa A.D. 150. The first edition was published in Bologna in 1477 and was illustrated with a set of 27 maps, though scholars say that it is not known whether the printed maps were engraved versions of original maps made by Ptolemy, or whether they were constructed by medieval Greek scholars from Ptolemy's text.

From about 1544, many maps were produced, especially in the important trading centers of Rome and Venice. Each publisher worked together, producing maps based upon their own needs and interests. The maps often varied dramatically in size. Over time, it became common to bind the maps together into composite works. Although the term atlas was not in use in 1544, these works are now called "IATO" atlases - (Italian, Assembled to Order) or more frequently "Lafreri atlases" after one of the leading publishers of the period.

Abraham Ortelius is credited with issuing the first modern atlas on May 20, 1570. His Theatrum Orbis Terrarum, contained 53 map-sheets covering the countries of the World. This work was the first book of its kind to reduce the best available maps to a uniform size. It was an immediate critical and commercial achievement.

However, use of the word "atlas" for a bound collection of maps was not to come into use until the 1595 publication of Gerardus Mercator's "Atlas, Sive Cosmographicae Meditationes De Fabrica Mundi ..." (Atlas, or Description of the Universe) (Duisburg, 1585-1595).

"Atlas" etymology

The origin of the term atlas is a common source of misconception, perhaps because two different mythical figures named 'Atlas' are associated with mapmaking.

• King Atlas, a mythical King of Mauretania, was, according to legend, a wise philosopher, mathematician and astronomer who supposedly made the first celestial globe. It was this Atlas that Mercator was referring to when he first used the name 'Atlas', and he included a depiction of the King on the title-page.
• However, the more widely known Atlas is a figure from Greek mythology. He is the son of the Titan Iapetus and Clymene (or Asia), and brother of Prometheus. Atlas was punished by Zeus and made to bear the weight of the heavens (the idea of Atlas carrying the Earth isn't correct according to the original myth) on his back. One of Heracles's labours was to collect the apples of the Hesperides. Heracles went to Atlas and reasoned with him. Eventually, Atlas agreed to collect the apples, and Heracles was left to carry the weight. Atlas tried to leave Heracles there, but Heracles tricked him and Atlas was left to carry the heavens forever. In his epic Odyssey, Homer refers to this Atlas as "one who knows the depths of the whole sea, and keeps the tall pillars who hold heaven and earth asunder".
