FIRST DUTCH GUIDE ON THE ART OF NAVIGATION
Coignet's Dutch translation of Pedro de Medina's Arte de Navegar, issued in combination with his own practical navigation guide, was the first great book in Dutch on the art of navigation and was consequently an enormous stimulus to Dutch seamanship.
The first Spanish edition of Pedro de Medina was printed in 1545 and was followed by numerous later editions and translations into French (1554), Italian (1554), Dutch (1580) and English (1581). The Dutch edition is of highest significance as containing the important treatise of Michel Coignet.
(Nico Israel, Catalogue 22, 1980)
Pedro de Medina's Arte de Navegar (the Art of Navigation) (Sevilla, 1545) was the first and only pilot guide of the 16th century on ocean crossing navigation, at a time when all other pilot guides were written for coastal navigation in European waters. The 1545 first edition is considered unobtainable and of high value. The book was translated in French, Italian, Dutch and English. Medina's Art of Navigation was instrumental for the early European age of exploration.
In 1580, Michiel Coignet of Antwerp translated Pedro de Medina's pilot guide in Dutch and issued it in combination with his own new pilot guide Nieuwe onderwysinghe op de principaelste puncten der Zee=vaert (New teachings on the principals of Navigation).
As Schilder writes:
"Coignet's contribution was even more practical than that of De Medina, and the ordinary seaman found it clearer and easier to understand. Coignet's Nieuwe onderwysinghe treats the practice of navigation in more depth. It also presents a clear discussion of the principles of navigation, the winds, sea charts, and determining one's position at sea. Furthermore, it gives an extensive description of the current instruments of navigation such as the astrolabe, cross-staff, and the noctolabe. The contribution by Coignet increased the value of De Medina's book considerably".
Noteworthy is that Coignet even gives details on how to construct accurate navigation tools.
The Coignet/Medina pilot guide for ocean navigation was a book of utmost importance. Multiple copies for the pilots and the captain were on board of all early Dutch fleets crossing the oceans and circumnavigating the globe. The book was first issued in 1580 and re-issued three times, in 1589, 1592 and 1598.
From around 1595, the Dutch commanders and pilots of the pre-VOC companies were thoroughly educated by Petrus Plancius in long-range navigation on the high seas, based on knowledge from Iberian sources. He played a big role in the education and training of officers for the Amsterdam expeditions to the Far East. The directors of these pre-companies richly rewarded him for his services.
The navigators and skippers were trained using Coignet's new navigation guide, that was bound with his Dutch translation of the Medina.
Plancius had great involvement in the training and examining of the steersmen of the first Dutch Fleet to the Indies of 1595-97, and for this fleet specifically trained Frederick de Houtman and Pieter de Keyser to map and name the unrecorded celestial constellations on the southern hemisphere, many of these still bear the names that de Keyser and de Houtman gave to them.
He was also involved, together with Robert Robertsz le Canu, in the navigational training and route planning of the three Amsterdam polar expeditions commanded by Barentsz that sought to find a northeastern passage to the Far East.
The wooden lodge where Barentsz crew wintered at Novaya Zemlaya in 1596-97 in their attempts to reach China and the Spice Islands via a northeast passage, was rediscovered in 1871, almost 400 years after their epic efforts. Many artefacts were excavated, one of the most famous of which was a frozen copy of Coignet's navigation guide, now one of the exploration treasures of Amsterdam Rijksmuseum.
This was the first time that an arctic winter was successfully faced. The voyage stands in the first rank among the polar enterprises of the 16th century, and led to a flourishing whale and seal fisheries which long enriched the Netherlands.
Exceptionally rare navigation guide of which only a handful of examples have survived. Lacking in all collections.
Despite the high demand for the Coignet/Medina pilot guide, the book is impossible to find, because it was a practical tool used and worn out on board of ships, not a book for armchair travelers. The book is so rare that it until 1975 no copies of this pilot guide was in any the Dutch Maritime Museums. Among the few surviving copies of the first edition is the one kept in the Rijksmuseum in Amsterdam. It was left on the island of Novaya Zemlaya in 1597 after the succesful wintering of Willem Barentsz and his men and was recovered, badly damaged, by the Norwegian captain Ellis Carlson in 1871.
First part quires F and G misbound before quire E; minimally browned/ foxed; partly with water stains in lower margin. Very fine condition. Original contemporary vellum binding.

The first manual to make a clear distinction between Pilotage, Navigation and Cosmography

Books on the art of navigation and cosmography, published by Cornelis Claesz
Around 1580, at the start of the great voyages that were to bring the first Dutch ships to the East and West Indies by the end of the sixteenth century, navigation took new pathways in its development. To sail on the open ocean, Dutch navigators had to have much greater skills than they had needed to sail along the European coasts. Now, they had to leave the familiar coastlines and venture out into unknown waters. Seeking guidance, Dutch seafarers naturally looked for mentors in Spain and Portugal. These two countries already had a long history of sailing the world's seas; they had built up sailing experience and had given the art of navigation a scientific basis. The knowledge that was locked up in foreign-language books suddenly took on a much greater relevance for Dutch navigation. The arsenal of information that existed in the Netherlands was greatly expanded when translations appeared of well-known reference works and textbooks from countries where navigational techniques were already more advanced. Besides the Iberian Peninsula, this also included England, where the art of navigation had reached new heights. It is not surprising that Cornelis Claesz seized the opportunity; he made sure that the pertinent publications also came out in Dutch editions.
Pedro de Medina and his Arte de navegar
Learned astronomers and geographers established working relations with men whose knowledge was drawn from experience. The problems these seamen had encountered in the course of their travels were unknown in coastal navigation. The success of such collaboration on the Iberian Peninsula led to the publication of important standard works on the art of navigation. Thanks to Pedro de Medina (1493-1567), developments in the technique of navigation could spread throughout much of Europe. His Arte de navegar, the most important manual in the field, was published in 1545 in Valladolid. No later editions of this work appeared in Spain itself. Nonetheless, the numerous editions in other languages – French (14), Italian (3), Dutch (4), and English (2) – gave this work its great importance for the advancement and proliferation of techniques of navigation.
The earliest Dutch edition, entitled De Zeevaert Oft Conste van ter Zee te varen, appeared in Antwerp in 1580. It was published by Hendrick Hendricksen in a translation by Maarten Everaert of Bruges. It was this edition that Willem Barentsz and Jacob van Heemskerck took along on the third polar expedition of 1596. It was this same Antwerp edition that they left behind after their famous winter on Novaya Zemlya. Nearly three hundred years later it was found there ([frozen in ice] now in the Rijksmuseum collection). The Dutch version of De Medina's work included a contribution by an adept in mathematics and navigation, namely Michiel Coignet (1549-1628) of Antwerp. Coignet's contribution was even more practical than that of De Medina, and the ordinary seaman found it clearer and easier to understand.
Later copies of this compilation were published in Amsterdam by Cornelis Claesz in 1589, 1592, and 1598. The Amsterdam and Antwerp editions were identical in content, except for the fact that the dedications (by the translator Everaert to Archduke Matthias of Austria, the other by Coignet to the Antwerp merchant Gillis Hooftman) were left out in the later three editions. New woodblocks were cut for the illustrations based on examples from the Antwerp edition. The title of the earliest edition published by Cornelis Claesz reads as follows:
De Zee=vaert oft Conste | van ter Zee te varen, vanden Excellenten Pilote Meester Peeter de Medina | Spaignaert.
Inde welcke niet alleene de Regels, Secreten, practijcken, en | constighe Instrumenten der seluer Consten begrepen zijn: Maer oock de | clare ende oprechte fondamenten der

Michiel Coignet's contribution follows suit to Medina's work; it is also supplied with Cornelis Claesz's imprint:

Apparently, the work of De Medina and Coignet was in great demand, because Cornelis Claesz published new editions in 1592 and 1598.
Thanks to the translation of De Medina's book, Dutch seafarers could learn about subjects with which they were supposed to be acquainted: the interpretation and use of the sea chart; the technique of calculating the latitude of their position by measuring the elevation of the sun and the Polar Star; familiarity with the compass; calculation of the phases of the moon and the tides; determination of the time at night from the position of the stars.
Coignet's Nieuwe onderwysinghe treats the practice of navigation in more depth. It also presents a clear discussion of the principles of navigation, the winds, sea charts, and determining one's position at sea. Furthermore, it gives an extensive description of the current instruments of navigation such as the astrolabe, cross-staff, and the noctolabe. The contribution by Coignet increased the value of De Medina's book considerably.

Nico Israel, Ernst Crone and Pedro de Medina's
De Zeevaert oft Conste van ter Zee te varen
Having been asked to contribute to this Liber Amicorum of Nico Israel, I checked to see how many items were acquired from Nico Israel over the years by the Nederlands Scheepvaart Museum in Amsterdam. I discovered that the total outnumbers a hundred and consists of books, manuscripts, charts, maps and a single instrument. As the diversity of these acquisitions will not allow for a homogeneous contribution, I decided to pick out one object, a book, of which I know that Nico Israel has special memories. The book in question did not come to the Museum directly from Nico Israel, but as part of the library of the late Dr Ernst Crone, which was left to the Museum in 1975.
One of the most famous collections of early pilot guides and navigational instruments was put together over many years by Dr Ernst Crone (1891-1975) from Amsterdam. His collection, the Crone Library, is now part of the Scheepvaart Museum in Amsterdam (Maritime Museum). Ernst Crone became one of the main benefactors of the Scheepvaart Museum in Amsterdam. From 1927 onwards he was a Trustee and from 1938-67 he was Chairman of the Board of Trustees. His position as a Trustee could have given cause for conflict with his private collectorship. Rather than allowing this to happen, an agreement was made between Crone and the Museum. Whenever an important navigational manual were to turn up, which both Crone and the Museum wanted for their libraries, a consultation was to take place between the collector and the Director of the Museum. Often Crone would be the buyer as the Museum was then an unsubsidised private institution. The little money available for acquisition had to be spent with great care. It was also agreed that the Museum would not buy books already present in the Crone Library. When, eventually, the two libraries would come to be united, and there was no doubt that one day this would happen, a large library on the history of navigation would result. The merger was effected after the death of Ernst Crone when, with the help of Nico Israel, the Crone Library was sorted and valued before being transferred to the Museum.
The books of which Crone was proudest were those by Pedro de Medina. The Arte de Navegar has been of great importance for spreading the art of navigation in Europe. It was translated into French, Italian, English and Dutch.
In Crone's memoirs he explains how he acquired his first Coignet/Medina copy. In 1926 the library of Jonkheer J.W. Six van Vromade was to be auctioned in The Hague. Among the books was a 1598 edition of the book [same edition as the one on offer here]. Crone was determined to buy it but was informed by the Director of the Scheepvaart Museum W. Voorbeijtel Cannenburg that W.A. Engelbrecht in Rotterdam was also bent on getting that book. Engelbrecht became an important benefactor of the Maritiem Museum 'Prins Hendrik' in Rotterdam when, after his death, his large and important collection of charts, atlases and navigational manuals was left to that Museum. Although both he and Crone collected in the same field, they rarely crossed swords. The opportunity to buy a Dutch De Medina was such a rare occasion. Crone learned that Engelbrecht was prepared to pay no less than f 1,400 for the book, then a large sum of money. With this Engelbrecht hoped to outprice Crone. The latter, however, wanted to avoid a confrontation in the auction room which would almost certainly have led to a fancy price. Through the intermediary of Voorbeijtel Cannenburg he proposed to Engelbrecht that they should buy the book jointly and then present it to the Scheepvaart Museum where there was no copy of this book. Engelbrecht agreed and the book was bought by Voorbeijtel Cannenburg at the auction for f 140, only ten percent of the sum Engelbrecht had been prepared to spend. Many years later another copy of the 1598 edition came on the market. Crone, still without a Dutch De Medina, offered Engelbrecht half of f 140 for the right to buy this copy. Engelbrecht agreed and, at last, Crone became the owner of a Dutch De Medina.
(Willem Mörzer Bruyns, former curator of Amsterdam Maritime Museum)
The Iberian ventures into the New World and into the Indian Ocean quickly and profoundly changed the nautical techniques that were required to safely perform the profitable transoceanic enterprises. It required skilled pilots that mastered the new mathematized celestial navigation. This "large", blue-water navigation forced mariners to not look to the coast to orient the vessel but skyward. The questions remained the same; What was the ship's location, and how could it best reach port safely. However, further out to sea it was no longer possible to identify one's position by observing familiar landmarks or by testing the ocean floor for depth or composition (sand of specific colour, shells, mud, rocks, and so on).
In 1508, Ferdinand II appointed Amerigo Vespucci as Spain's first inaugural piloto major, charging him with examining the pilots who sailed to the Americas and with approving their maps, instruments, and rutters. Sailors had to make independent arrangements for private classes to prepare for these exams, until in 1552 the Casa de Contratación (the "House of Trade" in Seville) established a formal navigation school, chaired by a cosmographer. In the centuries ahead, it would serve as a model for maritime communities accross Europe.
The teaching was done by university-trained instructors appointed by the king, who were expected to replicate the book-bound systems with which they were familiar, in this way eliminating the limitaions and flaws of oral communication that had aided the mariners in the centuries past. As an example, the instructors were required to teach the astronomy books by Petrus Apianus and Gemma Frisius, but also the first two chapters of Johannes de Sacrobosco's De Sphaera, the standard introduction to the Aristotelian structure of the heavens that defined and explained the mutual relationship between the celestial bodies as well as their relationship to a moving vessel far below.
Our students found themselves in a classrooms with a group of fifteen or so others, listening to twice-daily lectures straight out of a university textbook. This textual, classroom-based approach was a perplexing strategy for teaching men who were in all likelyhood not literate, who had until then effectively acquired their professional skills aboard a hip under the tutelage of more senior mariners, and who were accustomed to learning with eye and hand as well as with ear.
The most important book of all was Pedro de Medina's Arte de Navegar ("The Art of Navigation"), the first comprehensive guide for ocean navigation, that combined cosmography with the techniques and instruments of practical navigation. It was profusely illustrated with endless examples, illustrations, diagrams, volvelles and detailed chapters on the heavens, the seas, the winds, the height of the Sun, the poles, and the magnetic compass. The final two chapters treat the Moon and the days of the year and their relationship to the tides. This approach - defining the components of the universe in descending order from the grandeur of the spheres down to intervals of days and minutes - is a key trait of the "cosmographical" nautical manual.The work also includes astronomical tables - the "regiments" of the Sun and stars - that enabled mariners to determine latitude by measuring the altitude of these celestial bodies.
The Arte de Navegar was first published in 1545 in Valladolid. It was dedicated to the future Philip II, in support of Medina's quest to be appointed royal cosmographer. This work was an overview of existing knowledge on this subject, and was in a sense a revision and expansion of his "Book of Cosmography" of 1538, which had already been examined by the Council of the Indies. Arte was the first treatise on celestial navigation, and would soon be followed by a book by Martín Cortés de Albacar (son of Hernando Cortes and ....), published in Cádiz in 1551. Pedro de Medina had already served the crown as a consultant on maritime matters and taught in Cadiz from 1530 on. In his dedication to Philip II, he conjured up a concerning vision of mariners on "long dangerous voyages" where few of them knew the necessities of navigation because "there were no teachers to teach them, nor books to read". His work would set the standard for navigational textbooks for years to come.
The transmission of the Arte from Spain to the Low Countries went by way of Antwerp, where Michiel Coignet published a Flemish translation of Medina in 1580. Coignet, whose own important work was published as an appendix to his translation of Medina's Arte, explained that "large navigation" not only required all common practices of coastal navigation, but also "many other diverse and ingenious rules and instruments taken from the arts of Astronomy and Cosmography." In his work, we see two different models in play: the academic framework of the Spanish tradition juxtaposed against the more practical, enrepreneurial Dutch usage, the one beginning with cosmographical definitions, the othe with pragmatic calendrical data. Coignet, an engineer and wine gauger, brought different interpretive skills to the same material, choosing different things to illustrate, striving to elucidate complex material in creative ways. His choice was to show what was important to these sailors. What did they find difficult? What did the readers already know?
There were topics that were viewed very differently. For instance, while the Spanish texts emphasized the fundamentals of astronomy and cosmography, with diagrams and definitions about the structure of the world and the heavens, the Dutch text books include lessons on how to calculate the tides. The Dutch were less interested in the physics behind the tides than in how to compute their timing. It was imperative to teach mariners how to use the tables but also to equip them to compute the tides if the tables were outdated or absent. Given the North Sea's shallow coasts and strong tides, tracking the daily cycles was crucially important, for miscalculating by an hour could mean that a fleet would be trapped in port or, worse, stranded on a sandbar. By contrast, the Iberians had only trivial tides to deal with, especially in the predictable Meditterranean.
Sailing across the World's Oceans
The 1545 issue of Pedro de Medina's Arte de Navegar is one of the earliest pilot guides detailing the Art of Navigation. As it is at the basis of the development of Dutch maritime navigation, we will discuss its content.
Chapter 1 starts off as a book on Cosmography leading up to navigation at sea. It considers the earth as round but still fixed at the centre of the universe (geocentric or Ptolemaic model), which is subdivided into to eleven ‘peels' or 'heavens' with the sun orbiting the earth on the fourth of these 'heavens' in our solar system. The stars are located at the eighth 'heaven'. The moon and planets are properly sequenced from 'heaven' one for the moon to 'heaven' seven for Saturn.
Chapter 2 discusses the seas and the oceans with the movement of the waters, forecasting of storms and St. Elmo's fire.
Chapter 3 explains the winds, how they come about and stating that they are two-dimensional (sic!) only. This chapter further delves into navigation by discussing the compass, charts and distances, 'winds' or 'rhumbs', latitude on earth and the conversion of miles covered into delta values for latitude and longitude on earth.
Chapter 4 discusses the use of the sun for navigation, mostly by using shadows cast by sunlight. The explanation of the sun's declination is interwoven with the examples proffered and declination tables follow for four years, thus including a leap year. Dates refer to the Julian calendar still as the Gregorian calendar was not in use until 1582 and both calendars have co-existed for quite a number of years. Fixed holidays are marked and mobile festive holidays may be calculated for the years from 1545 to 1600.
Chapter 5 is a treatise on the Arctic and Antarctic Poles, the North Star (Polaris) and the Southern Cross and their significance for navigation at sea and calculation of local time of the night.
Chapter 6 addresses the magnetic compass, the magnetic variation and the lodestone and some problems of the needle array.
Chapter 7 covers the moon, its phases and influence on the tides, calculation of the 'golden number' and the occurrence of the tides time-wise and their effect on rivers. The moon's eclipse is discussed as well.
Chapter 8 addresses the time of day, time difference on earth, the duration of day and night, for the equator and at latitude and sunrise and sunset. Use of equinoctial time at 4 minutes per equator degree is explained; at the time maybe unusual ('vulgar hours' of daylight were common at the time), but astronomically making sense and still in use today as our regular time reference. The last tables record the longest duration of the day(-light) for any given latitude.

The Mapping of the World
On page 26 of Medina's rare work, the Arte De Navegar, is a small round world map encircled by eight cherubic windheads. Europe, Asia, and Africa are marked and part of America is shown in simplified form.
Medina was examiner of pilots for the Indies and a historian of repute. His book on navigation was popular and was translated into French, German, English and Italian. The same world map appears in the editions from Venice in 1554, 1555 and 1609, (and possibly in other editions) but not as far as I am aware in the editions printed in France.
(Shirley Map 84 on the small Medina world map, but he is unaware aware of the similar Coignet world map)
Michiel Coignet was the son of the goldsmith and instrument maker Gillés Coignet. After working as a schoolmaster, he worked as Antwerp's wine gauger, and entered the service of the Archdukes Albert and Isabella of Austria as a mathematician and siege engineer. In about 1584 he set up his own workshop producing astrolabes, sundials, armillary spheres and surveying instruments.
Coignet invented several instruments and corresponded with Galileo Galilei (from 1588), Gerhard Mercator, Godefroy Wendelin, Ludolph van Ceulen and Fabrizio Mordente, whom he met during the latter’s 1584 sojourn in Antwerp. Among other things, Coignet invented and described instruments that had a function similar to that of the proportional compass. During the dispute over the invention of the proportional compass in 1610, Giovanni Camillo Gloriosi attributed the invention to Coignet and not to Galileo.
Strongly encouraged and financed by Gillis Hooftman, in 1580 Coignet published a treatise on navigation entitled Nieuwe Onderwijsinghe op de principaelste Puncten der Zeevaert ('New Instructions on the Principal Points of Navigation'). It was published by the Antwerp publisher Hendrik Hendriksen, as an appendix to the Dutch-language translation of Pedro de Medina's Arte de Navegar. In the appendix he pointed to the possibility of determining longitude at sea with watches on the ships. He also described some of his newly invented instruments such as the nautical hemisphere. The nautical hemisphere is an instrument with which the longitude problem could, in theory, be solved.
Around 1600 Coignet became involved in the publication of atlases. He edited various editions of the world maps of Abraham Ortelius. He added an introduction on projections and 13 maps to some editions of Ortelius' Epitome atlas. The Latin-language Epitome was quickly translated into English and French. Coignet edited the French version published in Antwerp. One of the new maps was a map with a description of Japan, for which he had obtained the information from Jesuit sources. Coignet also added an introduction to the atlas Speculum Orbis terrarum of Gerard de Jode.
Pedro de Medina (1493 – Seville, 1567) was a Spanish cartographer and author of navigational texts. His well-known Arte de navegar ("The Art of Navigation", 1545) was the first work published in Spain dealing exclusively with navigational techniques.
In 1545 Medina published his most important work, Arte de navegar ("The Art of Navigation") in eight volumes. It was dedicated to the future king Philip II, in support of his quest to be appointed royal cosmographer. This work was an overview of existing knowledge on this subject, and was probably a revision and expansion of his "Book of Cosmography" of 1538, which had already been examined by the Council of the Indies. Arte was the first treatise on navigation to be published in Spain. The senior cosmographer Alonso de Chaves demonstrated that Medina's Arte was a compilation, made with the assistance of other writers. Diego Gutiérrez and other authors claimed that they had helped with parts of the book, and Medina himself acknowledged the assistance of Francisco Faleiro and Alonso de Santa Cruz on other occasions, but not with the writing of Arte. The book was internationally disseminated and quickly translated into several European languages: it was translated into French fifteen times between 1554 and 1663, four times into Dutch (1580-1598), three times into Italian (1554-1609) and twice into English. This work contributed considerably to the development of navigation on the high seas.
