Abraham Ortelius

Abraham Ortelius was a highly influential cartographer and geographer. He lived during the 16th century in Antwerp. At that time, Antwerp was located in the Spanish Netherlands. Ortelius is most famous for creating the first modern atlas. This collection of maps was titled the *Theatrum Orbis Terrarum*, or the "Theatre of the World." His work helped start the Golden Age of Netherlandish cartography. This era of map-making lasted from about 1570 to 1670.

Ortelius began his career as a map-engraver. He joined the Antwerp Guild of Saint Luke in 1547 as an illuminator of maps. An illuminator is someone who decorates or adds color to works. He also made money by trading books, prints, and maps. In 1554, he attended the Frankfurt book and print fair. There, he met the famous Gerardus Mercator. Traveling with Mercator to places like Trier and Poitiers influenced him. This experience pushed him toward becoming a scientific geographer.

His career included many specific map publications. In 1564, he released the *Typus Orbis Terrarum*. This was a large, eight-leaved wall map of the world. He followed this with a two-sheet map of Egypt in 1665. In 1667, he created an eight-sheet map of Asia. He also produced a six-sheet map of Spain. In 1589, he published the *Maris Pacifici*. This was the first dedicated map of the Pacific Ocean to be printed.

In 1570, Ortelius published the first edition of his famous atlas. It contained 53 maps. This work was a major achievement of research and hard work. The atlas was very successful and stayed in demand until 1612. Many different language versions were printed. These included Dutch, French, German, and Latin editions. Before his death in 1598, twenty-five Latin editions had been released. Many of these maps were reproductions of work by other artists. He listed 87 different authors in his first edition. By 1601, that list grew to 183 names.

Ortelius was also a scholar of ancient geography. In 1578, he published the *Synonymia geographica*. This book provided a critical look at how ancient places were named. He also published the *Parergon* in 1579. This was a series of maps showing ancient history and sacred sites. His interest in the past extended to collecting coins and antiques. He even wrote a book about heads of gods and goddesses from his own museum.

One of Ortelius's most remarkable ideas involved the movement of the Earth. In his 1596 work, *Thesaurus Geographicus*, he made a bold suggestion. He noticed that the coasts of America and Europe-Africa looked like they fit together. He proposed that the continents were once joined. He suggested they had broken apart and drifted to their current positions. This idea is known as continental drift. For many centuries, this theory went unnoticed or unproven.

Scientific proof for Ortelius's idea arrived much later. In 1912, Alfred Wegener published his own hypothesis about continental drift. Wegener is often credited by geologists for recognizing the possibility first. Later, in the 1960s, new evidence appeared regarding the seafloor. Scientists like Harry H. Hess studied seafloor spreading at mid-oceanic ridges. This provided the physical evidence that the continents do move. After more than 300 years, Ortelius's early observation was finally proven correct.
