1570 Ortelius Map of England, Scotland and Ireland

Abraham Ortelius (April 14, 1527 - June 28, 1598) also known as Ortels, was a cartographer, geographer, and cosmographer of Brabant, active in Antwerp. He was the creator of the first modern atlas, Theatrum Orbis Terrarum and is a seminal figure in the history of cartography. Along with Gerard Mercator and Gemma Frisius, he was a founder of the Netherlandish school of cartography. His connections with Spain - culminating in his 1575 appointment as Royal Cartographer to King Phillip II of Spain - gave him unmatched access to Spanish geographical knowledge during a crucial period of the Age of Discovery. Ortelius was born in 1527 in Antwerp. In 1547 he entered the Antwerp Guild of Saint Luke as an illuminator of maps. He began trading in books, prints, and maps, traveling regularly to the Frankfurt book and print fair, where in 1554 he met Mercator. He accompanied Mercator on journeys throughout France in 1560 and it was at this time, under Mercator's influence, that he appears to have chosen his career as a scientific geographer. His first published geographic work appeared in 1564, an eight-sheet cordiform world map. A handful of other maps preceded the 1570 publication of the first edition of the Theatrum Orbis Terrarum, which would prove to be his life work. Appearing with but 53 maps in its first edition, Ortelius' work expanded with new maps added regularly. By 1592, it had 134 maps. Many of Ortelius' maps remained the standard for nearly a century. He traveled extensively, but his genius was as a compiler, locating the best informed maps on which to base his own. His contacts throughout Europe and extending even (via the Portuguese) to the Far East were formidable. Moreover, many of his maps were based on his own scholarship, particularly his historical works. His theories of geography were particularly ahead of his time with respect to the notion of continental drift, the possibility of which he mused on as early as 1596, and which would be proven correct centuries later.

In a sense his greatest achievement was his successful navigation of the religious and political violence endemic to his city throughout his adult life: The Dutch Revolt, or Eighty Years' War (1568 - 1648), fully embroiled Antwerp. Although outwardly and officially recognized as Catholic (Arias Montanus vouched for Ortelius' Catholic orthodoxy prior to his appointment as Royal Geographer), Ortelius was able to separate himself from the religious furor which characterized the war in the low countries. Ortelius showed a glimpse of himself in a letter to a friend, regarding humanist Justus Lipsius: 'I do not know whether he is an adherent of the Pope or a Calvinist, but if he has ears to hear, he will neither be one nor the other, for sins are committed on both sides'. Ortelius' own explorations of Biblical history in his maps, and the Christogram contained in his own motto, suggest him to be a religious man, but his abjuration of political religious authorities mark him as an individualist. His tombstone at St Michael's Præmonstratensian Abbey in Antwerp bears the inscription, Quietis cultor sine lite, uxore, prole. ('served quietly, without accusation, wife, and offspring.')

Gerard Mercator (March 5, 1512 - December 2, 1594) is a seminal figure in the history of cartography. Mercator was born near Antwerp as Gerard de Cremere in Rupelmonde. He studied Latin, mathematics, and religion in Rupelmonde before his Uncle, Gisbert, a priest, arranged for him to be sent to Hertogenbosch to study under the Brothers of the Common Life. There he was taught by the celebrated Dutch humanist Georgius Macropedius (Joris van Lanckvelt; April 1487 - July 1558). It was there that he changed him name, adapting the Latin term for 'Merchant', that is 'Mercator'. He went on to study at the University of Louvain. After some time, he left Louvain to travel extensively, but returned in 1534 to study mathematics under Gemma Frisius (1508 - 1555). He produced his first world map in 1538 - notable as being the first to represent North America stretching from the Arctic to the southern polar regions. This impressive work earned him the patronage of the Emperor Charles V, for whom along with Van der Heyden and Gemma Frisius, he constructed a terrestrial globe. He then produced an important 1541 globe - the first to offer rhumb lines. Despite growing fame and imperial patronage, Mercator was accused of heresy and in 1552. His accusations were partially due to his Protestant faith, and partly due to his travels, which aroused suspicion. After being released from prison with the support of the University of Louvain, he resumed his cartographic work. It was during this period that he became a close fried to English polymath John Dee (1527 - 1609), who arrived in Louvain in 1548, and with whom Mercator maintained a lifelong correspondence. In 1552, Mercator set himself up as a cartographer in Duisburg and began work on his revised edition of Ptolemy's Geographia. He also taught mathematics in Duisburg from 1559 to 1562. In 1564, he became the Court Cosmographer to Duke Wilhelm of Cleve. During this period, he began to perfect the novel projection for which he is best remembered. The 'Mercator Projection' was first used in 1569 for a massive world map on 18 sheets. On May 5, 1590 Mercator had a stroke which left him paralyzed on his left side. He slowly recovered but suffered frustration at his inability to continue making maps. By 1592, he recovered enough that he was able to work again but by that time he was losing his vision. He had a second stroke near the end of 1593, after which he briefly lost speech. He recovered some power of speech before a third stroke marked his end. Following Mercator's death his descendants, particularly his youngest son Rumold (1541 - December 31, 1599) completed many of his maps and in 1595, published his Atlas. Nonetheless, lacking their father's drive and genius, the firm but languished under heavy competition from Abraham Ortelius. It was not until Mercator's plates were purchased and republished (Mercator / Hondius) by Henricus Hondius II (1597 - 1651) and Jan Jansson (1588 - 1664) that his position as the preeminent cartographer of the age was re-established.
