#LoveMaps – Bob Silvester

Dr Bob Silvester, FSA, Visiting Professor, University of Chester takes part in our #LoveMaps campaign.

A professional archaeologist for all of his working life, first in Devon and Somerset and later in Norfolk, he moved to Wales in 1989 when appointed deputy director of the Clwyd-Powys Archaeological Trust. He retired from CPAT at the beginning of 2016, and for research purposes he is now affiliated to the Department of History and Archaeology at the University of Chester. His interest in all types of historic maps, but especially estate mapping, emerged during his time in the Norfolk fenlands where maps were a vital adjunct to the fieldwork that was unravelling the development of the historic landscape. Over the last twenty-five years his interest in mapping has grown, and now with retirement, he is able to spend more time immured in local record offices and, of course, the National Library, examining maps of east Wales and the adjacent border counties in England.

Edward Matthews’ map of Llanarmon Mynydd Mawr

Thomas Slaughter and Richard Richardson will be familiar names only to those who have a deep interest in eighteenth-century mining activity in Wales. Slaughter is a fairly obscure individual, but Richardson was more obviously eminent, a goldsmith, an alderman in Chester for many years, and in 1757 the city’s mayor. As mining entrepreneurs they commissioned mapped surveys of areas likely to have unexploited mineral deposits prior to leasing the land from its owner. Edward Matthews, the first generation of a family of surveyors based in Mold in Flintshire, seems to have been their preferred choice and his name appears on a number of maps including two from the 1750s of the Chirk Castle estate holdings of Llanymynech Hill near Oswestry and the less well-known Voel Fawr as it is termed on the map shown here, the most prominent hill in the parish of Llanarmon Mynydd Mawr, historically in southern Denbighshire but now in Powys. Slaughter, Richardson and Richard Myddelton, lord of Chirk all signed the map, presumably confirming it to be an accurate representation of this upland landscape.

Edward Matthews’ map cannot by classed as an estate map in the strict sense of the term. It shows only a very small portion of the lands owned by Richard Myddelton and indeed depicts the lands of other freeholders; it is better termed a property map, and for me this is one of its strengths. Had it just been a depiction of Myddelton’s farmed estate, the unenclosed mountain land that was Voel Fawr would have received little attention because of its limited agricultural interest. Here though it is the mountain that was important for its potential mineral reserves. Matthews shows the terrain as a series of humps, in a traditional fashion that had been adopted by Saxton nearly two hundred years before. He depicts the various slate quarries that had been opened on what was almost certainly still functioning as common land in the eighteenth century, and also old mine workings, seen as groups of black dots, which would have attracted the specific attention of Slaughter and Richardson, as they do the archaeologist of today.

Yet it is not the olive green wash employed for the mountain that attracts the eye, but the bright colours – brick red, yellow, slate green etc – adopted for the different freeholders’ lands, lying mainly to the south of a lane that tracked eastwards along the contours towards the hamlet of Llanarmon Mynydd Mawr. In particular it is the surprisingly mixed pattern of land holdings with strangely shaped fields which is of interest. And in this we are moving outside the province of archaeology and into that of socio-economic history, for the pattern is best explained as a consequence of the Welsh system of partible inheritance, whereby each of the deceased’s male heirs acquired an equal portion of his land. This contrasted with the English system of primogeniture where the eldest son normally inherited the entire estate. Matthews’ map unfortunately can’t provide the information as to when the fragmentation of the holding took place, and the irregular fields that show so clearly on his map are today barely visible in the landscape, having been swept away in a rationalisation of the field layout in the later nineteenth century.

A question remains unanswered. Why did the surveyor show the land of various farmers? The answer probably lies in the fact that Richard Myddelton was the lord of the manor and claimed the mineral rights across (or more accurately below) other men’s land. There is though no archaeological evidence to suggest that Slaughter and Richardson exploited this option.

Over the last twenty-five years his interest in mapping has grown, and now with retirement, he is able to spend more time immured in local record offices and, of course, the National Library, examining maps of east Wales and the adjacent border counties in England.

William Williams’ Denbigh and Flint

As an archaeologist I have found little of interest in county maps. Almost invariably they were drawn at a scale too small to show details of the landscape changes that are significant for us in our studies. Over years of working in north-east Wales, however, I’d periodically come across references to William Williams’ New map of Denbigh and Flint, generally attributed to 1720 or 1721, in books and articles without encountering the map itself. What such references shared in common was the claimed connection with a handful of others from the early eighteenth century, together exemplifying a ‘new wave’ of county maps that succeeded those of Saxton, Norden and Speed from the end the sixteenth and beginning of the seventeenth centuries, with William Williams’ map the sole Welsh representative in a distinguished line-up .

William Williams himself had an interesting if relatively brief career, producing some elegant estate surveys in the mid-1730s for big landowners in north-east Wales and Cheshire, before succumbing to a ‘gout in his stomach’ in 1739. He is though better known outside Wales for his volume of architectural drawings entitled Oxonia Depicta published in 1732-33. It was inevitable that in studying his estate surveys, I’d look at Williams’ earlier cartographic work, and two perhaps not unrelated facts soon emerged. One was that little had been written about the surveyor, a recent writer on Oxford’s historic architecture terming him obscure, which is probably in the context of middle England a fair comment. And of his county map, the only comments of substance are in a paper compiled by the National Library’s Glyn Walters in 1968. More intriguingly, it was apparent in 1968 and even more so today that despite the fact that this purports to be a printed map, only one original copy is known – that housed in the National Library – which might go some way to explaining why so little has been written about it.

At first sight Williams’ map is rather different from its county predecessors. It is in modern parlance ‘very busy’. There is hardly a square inch of spare space because the compiler has packed in around the perimeter of the map a large number of armorial shields, each seemingly crossed referenced by number or letter to the houses of the aristocracy and gentry that are marked on the map itself. For the most prominent families – the Grosvenors, the Mostyns, the Wynns – the heraldry is accompanied by drawn elevations of their principal country residences. As if this were not enough blank areas around the mapped counties are filled in with prospects of Chester and Denbigh, two of the counties’ great churches – Wrexham and Gresford – though not we might note the cathedral at St Asaph, and the lead works or ‘workhouse’ at Gadlis near Flint. Yet evidence is accumulating, though it’s something I’m still working on, that Williams adopted elements of Saxton’s late sixteenth-century map or perhaps more likely one of its later derivatives for his own plan, rather than surveying the two counties anew. He then corrected or updated place-names, perhaps removed one or two buildings that had disappeared during the previous century and a half, but compensated by adding large numbers of mansions as well some major roads.

There aren’t as far as I have been able to establish many published maps which displayed the characteristic of a map encompassed by the arms of the region’s leading landowners, though perhaps a reader of this blog may be better informed than I am. One that has just been fully published by the Cambridgeshire Records Society is Jonas Moore’s Mapp of the Great Levell of the Fenns from 1658, another is John Senex’s A New General Atlas… published in London where the numerous subscribers to his world atlas are represented across numerous introductory pages by their coats-of-arms. The date of the General Atlas – 1721 – is significant in the context of William Williams’ work, not least because at the end of the title band on the county map is inscribed L Senex sculp.t

Centres of Cartographic Attention

Global maps present challenges to cartographers. In attempting to represent the entire world, perplexing practical and political decisions have to be made. Practically, there is, of course, the issue of representing a three-dimensional sphere in two dimensions. This challenge has given rise to numerous map projections of the world, ranging from Mercator to Cassini, and from Goode homolosine to Gall-Peters. Each projection has its own merits, perhaps related to its ability to avoid distortion, or its potential utility for navigational purposes. Politically, there is the question of what to place at the centre of the map, and what you relegate to its peripheries. Should the focus of the map be the Greenwich Meridian or perhaps the poles (as we see in the disorienting Cassini projection)?

This political question of what should occupy the centre of our global cartographic projections provides a segue in to the map I would like to discuss within this post. This map of The World was prepared for the National Geographic Magazine ca. 1922. It has a number of interesting features. It outlines early trans-Atlantic aeroplane routes, many of which had been authorised, but not yet used (Charles Lindberg’s first solo flight across the Atlantic was not until 1927). The map also marks out several ‘unexplored regions’ in the Arctic and Antarctic. The map is based on the Van der Grinten projection. The projection is interesting for two main reasons. First, this is a ‘compromise’ map projection, which seeks to preserve the basic outlines of a Mercator map, while minimising its distortions. Second, the projection was conceived by one Alphon J. van der Grinten. Van der Grinten was an American who developed his map projections in the late 19th and early 20th centuries. Van der Grinten’s nationality may help to explain why the National Geographic Magazine (the magazine of the American National Geographic Society) may have commissioned a map based on this particular projection (van der Grinten projections are commonly found in the US). What is certain is that this particular projection accentuates the size and significance of Northern Hemisphere nations like the US, while diminishing the relative size of nations nearer to the Equator.

What most interests me about this map, however, is not its projection, but its central focus. The positioning of the Americas at the heart of the map should come as no surprise: this is, of course, common for maps produced for US audiences. However, giving the Americas pride of place has interesting consequences for other countries. Russia is cut crudely in half, with parts of Siberia in the eastern hemisphere and others in the west. India is unevenly dissected with the most easterly territories (today largely constituting Bangladesh) suddenly appearing on the far west of the world map. I have never been particularly comfortable with Britain being the centre of global maps, given the colonial ideologies this has historically supported. Nevertheless, the use of the Greenwich Meridian as the centre of a world map does appear to do the least amount of damage the cartographic representation of other states of the world (with the vast expanses of the Pacific Ocean offering the edges of the map). But even then, Pacific Island states can often see their territorial integrities disrupted. Cartographically speaking, it appears that whatever projections and modes of division are chosen, world maps can never please all of the nations all of the time.

The ‘last invasion of Britain’ and the and Ordnance Survey

My previous blogs in this LoveMaps Series have focused on the underlying geographical processes that maps can help to reveal, and the ulterior motivations that often inform cartography (maps are never innocent!) . These insights come together in my next choice of map, two Ordnance Survey sheets of Pembrokeshire. I initially chose to look at maps of Pembrokeshire because it is a county that holds special meaning to me. It is the site of my first holiday memories as a child, and the place I now take my own children every summer. When I was presented with these early Ordnance Survey maps of Pembrokeshire I was struck by their sophisticated simplicity. OS maps have the happy knack of being able to convey large amounts of useful cartographic information in an elegant and very readable form. If any maps were going to be “innocent” it was surely these. How wrong I was!

On first inspecting these maps in the National Library of Wales I learned that Pembrokeshire was the first area of the Wales to be mapped by the Ordnance Survey. The reasons for this were twofold. Firstly, from its inception in the 18th century the “Ordnance” Survey was an operation designed to support military operations in Britain. With revolutionary forces at play on the Continent, the Board of Ordnance was tasked with providing maps of England’s southern coast in case of invasion. The original Ordnance Survey was thus a survey focused on where best to locate military ordnance in the form of artillery in order to ward-off foreign invasion. Secondly, Pembrokeshire was the site of the most recent French invasion of Britain. The Battle of Fishguard was a short affair, which occurred on 22-24 February 1797. The French invasion of Pembrokeshire was actually a diversionary operation designed to distract Britain from a parallel invasion of Ireland, it failed spectacularly. Interestingly, it is now commonly referred to as the ‘last invasion of Britain’.

For me, these are two beautiful maps of a place I dearly love. But these are also maps with military purpose that can tell us something of the processes of state building and defence in 18th and 19th century Britain. The concern that these maps clearly show for elevated land, coastal details, and road and river routes were not designed to serve the travelling tourist, but the British military. These reflections may seem interesting (hopefully), but anachronistic: the OS is no longer in the service of the Britain military. This may be the case, but military interests will always shape national cartographic practices. Next time you pick-up an OS sheet, you may want to pay attention to the lack of detail they provide of existing military sites in Britain and what goes on there. Maps that once made things visible for military purposes can also assist in making things invisible when necessary.

There is no such thing as an innocent map

There is a popular misconception that maps merely reflect the territories that they have been drawn to depict. The idea of the map as a form of innocent representation has, however, long been challenged within more critical cartographic communities. Within human geography there is a popular, if somewhat counterintuitive, aphorism that maps precede territories, not territories maps (Pickles, 2012). I remember when I first read this statement thinking how radical it was. I knew that maps could not represent fully the complex territories they charted: the French philosopher Henri Lefebvre, for example, emphasizes the representational limits of maps when he asks, ‘how many maps, in the descriptive and geographical sense, might be needed to deal exhaustively with a given space, to code and decode all its meanings and contents?’ (1991: 85). While only an infinite number of maps may be able to deal exhaustively with a territory, what if there was more to the representational limits of maps than the practical selection of which features to depict and which to exclude?

Over time I have come to appreciate, and be fascinated by, the political motivations that inform the construction of maps. These motivations are not necessarily about lying through cartography, in the sense of deliberate misrepresentation, they are often more subtle attempts to generate political power and influence. Cadastral maps were among some of the earliest attempts to chart national territories in countries like Sweden. But these maps were not just about descriptions they were a basis for the generation of land taxes to fund early national governments. Global maps projections have long been associated with the projection of political power. Translating a three-dimensional sphere on to two-dimensional paper will always involve aspects of cartographic manipulation. But many global map projections have tended to emphasize the power and influence of colonial powers by maximising their territorial area and minimising those of colonialized states.

It was while looking at different global map projections in the National Library of Wales that I was shown this arresting ‘League of Nations Map of the World’. The League of Nations was established in the aftermath of the First World War, in order to create a diplomatic structure in and through which national territories could be peacefully administered and future conflict avoided. The map contains some interesting features, including: the flags of the League of Nations Member States (note the absence of the US and the USSR); pie charts demonstrating the presence of ethnic minorities in European States; and even a graph indicating the relative height of tariff walls. Perhaps the most intriguing feature of the map are the inserts that reveal the various Mandates through which Britain was tasked with administering territorially contested areas in Africa, the Middle East, and the Pacific.

This ‘League of Nations Map of the World’ interests me because it embodies an overt instance of a map preceding multiple territories. This map is an attempt to cartographically project a vision of an ordered international space, based upon peaceful interstate diplomacy, but which ultimately supports the continuance of the colonial power of European states. This map is also compelling because it marks a failed geopolitical project. The territorial compromises it projected in Europe would ultimately lead to the Second World War, while the territory covered by the Asiatic Mandate in the Middle East continues to be a focus of conflict and violence today. There is nevertheless, something fascinating about a map that can appear so authoritative, complete, and settled, but which we know now would be shattered by the ensuing geopolitical upheavals of the twentieth century.

Why I don’t always love maps!

It is customary when writing a blog of this kind to begin with an account of one’s personal devotion to maps and the wider cartographic sciences (particularly when you are geographer by profession, as I am). However, if I am to be candid, I have never really been “in to maps”. I don’t collect Ordinance Survey sheets, nor do I spend a lot of time reading maps—I am even a little fuzzy about the particular virtues of different mapping projections. The invitation to write this series of blogs has thus involved a certain degree of soul searching, as I ponder why I am not always inspired by maps. Asking this question has inevitably also helped me articulate more clearly why at other times I find maps just about the most interesting things there are to read.

This blog focuses on a map sequence of the Birmingham and Black Country Conurbation. These three maps depict urban development in the West Midlands from the 19th Century through to 1962. When considered in isolation these maps are fairly unremarkable. The first map shows Birmingham as a small town, flanked on the north west by a series of isolated industrial communities including Wolverhampton, Bilston, and Walsall. Between these early industrial settlements are large tracts of open space and farmland. The second sheet shows Birmingham in the first half of the twentieth century, now much expanded and beginning to merge with Oldbury and Smethwick to the west and Erdington to the north east. By 1962 we find a fully-fledged, multi-centred urban agglomeration stretching down to communities as far south as Redditch and fully integrated with the industrial centres of the Black Country. These three maps chart the transformation of small urban communities (each probably no more than 2 miles in diameter) into a continuous agglomeration of some 15 miles in width. For me, this is when maps become most interesting.

I think one of the reasons I have never been a cartophile is because when taken in isolation maps can appear to offer very settled depictions of the human and physical worlds. As a Marxist geographer by training I have always been encouraged to think of the world, and its constituent parts, not as things, but rather as processes. This distinction between things and processes is captured nicely in the distinction between the individual maps of Birmingham and the Black Country and the sequence of three maps taken together. In isolation, each map provides only a static snapshot of urban geography in the West Midlands. But in sequence these maps offer insights into the processes of urbanization. These are processes of geographical change that appear to be connected to the emergence of modern industrial capitalism in the West Midlands that attracted ever more migrants to the emerging economies of the area. They are also processes that concern the emergence of suburbs and the often overlooked, but increasingly powerful, land economy of cities.

Each year I take my third-year urban geography students to Birmingham. I begin the field activities atop the Library of Birmingham from where it is possible to get a sense of the vast scale of this modern conurbation. This year, as ever, I will encourage them to think of the city less as a thing and more as a set of ongoing processes. When understood in this way, it is possible to connect the processes of industrial urbanization that began in Birmingham with the historically unparalleled rates of urbanization that are now evident in China, India and Nigeria at the moment. Now that is why I love maps.

Why cataloguing matters – Portolan Chart by Domenico Vigliarolo, 1592

This rather damaged chart is one of the greatest, and also one of the least well known, treasures of the National Map Collection.

It is a portolan chart, an early navigation chart drawn using compass directions and distances estimated by sailors on their travels. Unlike modern charts they are not based on systematic survey and are not based on any map projection. The oldest known portolan charts date from the 13th and 14th centuries; dating from 1592 this chart is quite a late example. Portolan charts were so important as navigational aids that they were considered to be state secrets by many European governments at the time.

The chart shows the East coast of the Americas and West coast of Europe and Africa and it was designed for navigating the Atlantic Ocean, prominently named on the chart as Mar Oceano. One of the interesting things about the chart is the relative accuracy achieved by the mapmaker based only on compass observations and dead reckoning.

So why does accurate cataloguing matter? When I first came across the catalogue record for this chart the author was given as Dom Domingo. Unfortunately, this incomplete rendering of the name meant that this chart was not identified as being the work of Vigliarolo and consequently left out of published bibliographies of his work. It took me a fair deal of research to discover who Dom Domingo actually was.

In order for scholars and other users to be able to access the wealth of resources held in a repository such as the National Library accurate catalogues are important, otherwise items are not found by researchers and their work is then incomplete. Cataloguing is one of those back office functions that most people don’t really think about, until they can’t find what they are looking for, but it is a vital part of our work.
Producing accurate records which help users find what they need is part of my job in which I take great pride, so next time you look at a catalogue record remember the work that went into producing it.

History, propaganda and the ‘Fate of the U Boats”

Amongst the many anniversaries listed on Wikipedia for today is the 103rd anniversary of the introduction of unrestricted submarine warfare by the Imperial German Navy during the First World War. Seeing this brought to mind one of the maps from our collection of First World War maps which was recently digitised. We are currently in the process of making these images available on our Website and though this map is not yet available a large number of them can be seen

The map itself is on two sheets, it was published after the war in 1921, and is fascinating for the stories it is trying to tell, not only the story of the major battles such as Jutland, but also the story of the submarine warfare which really began with the decision to ignore the normal ‘rules of war’ under which submarines had to surface and allow merchant ships to surrender before firing upon them and to instead sink merchantmen without warning.

Unrestricted submarine warfare was a controversial tactic from the beginning and was one of the factors which eventually brought the United States into the war. The German’s argued that it was a response to the British use of Q-ships, armed naval ships posing as unarmed merchantmen. During the Second World War the Germans used unrestricted submarine warfare again and some wanted to treat it as a war crime after Germany’s defeat, however, it was pointed out that the US Navy had used the same tactic against the Japanese and so it was decided not to prosecute anybody.

Returning to the map itself closer examination shows that in addition to the story of the war in the North Sea between 1914 and 1918 the map also tells the story of the defeat of the Spanish Armada over 330 years earlier. By juxtaposing one of the great English naval victories of history with the actions of the modern Royal Navy in the war the map seeks to perpetuate the idea of British maritime supremacy. The heroes of the Armada are pictured alongside the heroes of the modern day. Another interesting feature is the list at the bottom left of the Southern sheet titled “Fate of the U Boats”; it consists of a chronological list of all the U-Boats destroyed during the war.

The map is an unashamed piece of propaganda; the Germans are clearly shown as the villains of the piece, the suggestion being that their tactics of unrestricted submarine warfare and use of Zeppelin airships are somehow underhand. It is interesting that such a jingoistic map should be produced several years after the war, it is much more akin to maps produced for propaganda purposes during the war and there are few equivalents of such a late date.

As a piece of cartography this map isn’t great, it is far too cluttered and tries to tell too many stories in a limited space, and yet every time I look at it my eyes are drawn to some new detail or piece of information. It may not be much of a map, but as a historical document it is fascinating.

The most boring map in the World

When tasked with choosing four maps from the National Library’s map collection to write about I was left with something of a dilemma, the easy option would be to go for some of the famous treasures, however, previous #LoveMaps contributors have already used many of these and those that are left may well excite the interest of future contributors.

So, what to choose? Well, I decided to go for some items which were slightly different and also to try to stick to a theme and what better theme than the Welsh Government’s chosen theme for the year 2018 The Sea.

The National Map Collection holds a large number of fascinating nautical charts, but my first choice is not a nautical chart it is an aeronautical chart. A map for navigating by air and this gives a clue as to why someone would produce a map with absolutely no features on it at all.

This featureless stretch of the Earth’s surface is part of the Pacific Ocean, there are no islands or other features to show where we are, and we are reliant on the titling and coordinate system to provide our location. This is, of course, the whole purpose of this map; it is designed to allow pilots and navigators to plot their course and position accurately on the map, when there are no features on the ground below to allow them to get their bearings. To be able to do this is vital if one is to reach dry land safely when crossing such a vast distance as the Pacific Ocean. Dead reckoning over such a long distance would almost inevitably lead to missing land (which could be a tiny atoll in the midst of the ocean) and then running out of fuel and ditching in the sea, with virtually no chance of being rescued.

Accurate locational information would have been vital during the Second World War when this chart was made. Aircraft flying from the US carrier fleets would need to be able to find their way to the enemy ships and home again without getting lost. Long-range scout planes would need to be able to plot the position of enemy ships in order to relay this information to the carrier groups.
During the Falklands War in 1982 the Royal Air Force was tasked with bombing the airfield outside Port Stanley, in order to do this they needed to fly their Vulcan bombers from Ascension Island to the Falklands a round trip of over 12,000 Kilometres. As nobody had ever expected to need to do this there were no aeronautical charts available of the South Atlantic, so the navigators had to use charts of the Northern hemisphere turned upside down in order to plot their course, with the Azores standing in for the Falklands.

In today’s world most air navigation relies on radio navigation aids and satellite positioning systems, but when such systems fail being able to work out where you are on a map, especially in the middle of an ocean, is still a valuable skill to possess.

So even this most featureless and boring of maps was a useful tool at the time it was produced and as such perhaps it is not as boring as at first it may seem.
