Johannes Baptista Vrients (1552 - 1612) was a Flemish engraver, publisher, and mapseller. Little is known of his early years, but it is to be assumed he came up as an apprentice among the mapmakers of Antwerp, where the guild named him a master in 1575. In the 1590s, he executed world maps for Plancius and Linschoten. (In 1600, after Ortelius died, he became the estate's executor and acquired the plates for the Theatrum.) He would go on to publish further editions of the Ortelius atlas between 1606 and 1612. Vrients also acquired the plates for Gerard De Jode's (1516/17 - 1591) Speculum in and around 1600, but he did not republish that work - though he would preserve the De Jode plates depicting the Electors of the Holy Roman Empire, reprinting it in his editions of the Ortelius atlas after 1603. Most likely, his purchase of the De Jode plates was a play to keep them off the market. Vrients' editions of the Theatrum were not published in Antwerp (that city having fallen during the Dutch war with Spain) but in Amsterdam. More by this mapmaker...

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.')

Giovanni Antonio Magini (June 13, 1555 - February 11, 1617) was an Italian astronomer, astrologer, cartographer, and mathematician. Born in Padua, he completed his studies in philosophy in Bologna in 1579. In 1588 he was chosen over Galileo Galilei as the chair of mathematics at the University of Bologna after the death of Egnatio Danti. Magini was a prolific writer, putting forth theories of celestial motion (he was a supporter of a geocentric solar system), the use of quadrants in surveying and astronomy, and trigonometry. In 1608, Magini produced the first map of Italy to improve on that of Gastaldi: his meticulously researched and beautifully engraved 8-sheet Italia Nuova was hugely influential: upon its publication, Blaeu promptly copied it to produce his own wall map of Italy; the rest of the mapmaking establishment swiftly followed suit. Consequently, virtually every 17th century map of Italy can be identified as a derivative of Magini's monumental achievement. His atlas, Atlante geografico d’Italia, was published posthumously by his son in 1620. This work was intended to include maps of every Italian region with exact nomenclature and historical notes. He also served as court astrologer for the Duke of Mantua. Learn More...
