Book review: This way up by Mark Cooper-Jones and Jay Foreman

My next review is of This way up: when maps go wrong and why it matters by Mark Cooper-Jones and Jay Foreman – a book about maps with something wrong with them, sometimes the errors are accidental but others are deliberate. It is based on the authors’ YouTube channel – Map Men – which has a rather broader scope.

The style of the book is very relaxed but varies from chapter to chapter, one is a podcast transcript, whilst another is a series of fictional letters. One chapter is one sentence long, asking whether a globe is a map (it isn’t).

The chapters are pretty much entirely independent of one another, although the authors note that Google Maps is a little bit of a recurring theme.

This Way Up sometimes talks about when maps are just wrong, for example IKEAs world map which omitted New Zealand, this mistake is sufficiently common that there’s a MapsWithoutNZ reddit. Related to this are erroneous maps on the TV. Both of these arise from the technical process of getting maps into production.

All maps are likely “wrong” because they contain fake places known as copyright traps to catch out people copying them – the chapter on this involves the fictional town of Aglow in the Catskill mountains which has been cited as a copyright trap but mysteriously became a real place – perhaps so that a copier could avoid a copyright challenge!

Some maps are “wrong” for political reasons, in disputed territories such as Kashmir or Taiwan. The UK has a relatively benign version of this, it is now illegal for public bodies to put Shetland in a box in public maps. I struggled with this chapter because it was written as a poem!

In the Soviet Union maps were routinely censored or rendered inaccurate for reasons of secrecy, an exercise in futility once satellite imagery became routinely available.

There are a couple of maps on the birth and growth of the United States, one illustrates it is ill-advised to base borders on vaguely known geography. The northern border with Canada in the west was based on the north west extremity of the Lake of the Woods – a rather intricate body of water, and a projection west to the Mississippi River which it turned out didn’t go so far north. The second map relates to the Donner Party, a group of American settlers heading out to California whose voyage ended in cannibalism. They had left Independence in Missouri rather late in the season which meant they risked being caught by snow in the Sierra Nevada mountains. As a result of this time pressure, they elected to take the “Hastings Cutoff”, a route promoted with a map – inaccurately as it turned out – which would have saved them time.

The “Mountains of Kong” appeared on maps of West Africa following James Rennell’s 1798 map, they persisted through the 19th century and have actually appeared on a map published in 1995. They don’t actually exist, which has been known since about 1890. Rennell had added them to his map on the basis of very limited information and with a desire not to leave blank spaces, his maps were used as the basis of further maps since original cartographic information was in short supply.

I liked the idea of the Situationists who got their own chapter illustrated by the two authors attempting to meet up in London using a map of Paris. The Situationists were an anti-capitalist French group formed in 1957 who believed in making spectacles, and one way of doing this was to navigate a city at random, using the “wrong” map helps this process.

Technically interesting was the creation of the ITV regions in the UK, these arose from the 1954 legislation to end the BBC monopoly on broadcasting (the campaign for this used the slogan “freedom of the knob”!) . The regions were sometimes culturally illogical because transmitters were costly and worked by line of sight, this meant that, amongst other things, South Wales was grouped with Bristol. Also interesting that London had two franchises, one for weekdays which went to Thames and the other for weekends, won by London Weekend Television! The ITV regions were part of my youth, they went into decline when Channel 4 was launched in 1982, and further when the franchises were auctioned in the early nineties.

I’ve read before about the issues of mapping in India, it features in The Address Book by Deirdre Mask. In the city slums many streets are nameless largely as a result of their informal creation but also because the Indians were left with many colonial street names which they didn’t particularly like. In This Way Up addresses and directions in India provide an opportunity to talk about Google’s efforts to improve direction descriptions by the use of landmarks which is how people in Indian were found to describe routes. Actually this is more generally true, I may be vague about street names in my area but I definitely know the landmarks.

The Marshall Islands were very intensively mapped by the Americans prior to the post-war atomic bomb tests conducted there which led to the invention of the more powerful fusion bomb. The surveys were done so that the impact of those tests could be measured. They produced bigger explosions than expected leading to the evacuation of a number of the islands due to long-lived fallout, a number of smaller islands were entirely erased from the map. Also in this chapter were the stick maps that the Marshall Islanders used for navigation.

The final chapter talks about the coming of sat nav and the Google Map, tracing route finding technology from Roman itineraries to a medieval version of such; a scrolling itinerary linked to the turning of a cars wheels from the 1930s (the Iter Avto); audio itineraries, recorded on tape, from the early seventies; the Philips Carin digital map finally resulting in the sat nav we now today which was a luxury car add-on in the nineties and then in everyone’s hands in the form of the smartphone from 2009.

An excellent book for holiday reading, not so good if you are looking for something a little more academic.

Book review: Four Points of the Compass by Jerry Brotton

My next review is of Four points of the Compass: The Unexpected History of Direction by Jerry Brotton. I read his book A History of the World in 12 Maps in 2013,

One might imagine that the history of the four points of the compass was a rather brief affair, and Four points is a relatively short book. However, it packs a lot in because the compass points are more than just geography – they encompass religion, culture and politics.

The book starts with an “orientation” chapter followed by chapters on east, south, north and west and finishes with one entitled “The blue dot”. In this case the blue dot is us; our marker on the map we now find on our phone. A fitting end since Brotton starts by talking about the Apollo 17 “Blue Marble” photograph – not to be mistaken for Carl Sagan’s “Pale Blue Dot” taken by Voyager 1 as it passed beyond Saturn in 1980. Brotton sees the rise of our blue dot on a phone as an end of the compass directions.

It is easy, particularly for the map obsessed, to think of the cardinal directions of the compass as being almost timeless, and it takes some prompting to recall that the words North, South, East and West have meanings beyond those physical directions. This is highlighted in the “Orientation” chapter.

The other source of direction in the human world is based on our own body: left, right, front, back, up and down. This creeps into the compass direction with the etymology of some languages linked to them, i.e. north is the left of east. The Guugu Yimithirr people of Queensland Australia don’t bother with these egocentric directions, referencing everything to the compass (“please, pass the salt to your west”). The up and down directions rarely feature alongside the compass directions, with the exception of Mesoamericans who for a considerable period added up as a fifth cardinal direction.

The first written references to compass-like directions are from the Akkadian culture from around 2000 BCE. They are compass-like since they relate to prevailing winds and weather rather than magnetic or astronomical dirctions. The second phenomena prompting direction, and probably the primary one is the sun which rises in the east and sets in the west. The invention of compass north and south comes rather later with the Chinese discovering what they called “south pointing stones” around 200 BCE. Magnetic compasses only became common as directional aids in 12th century in Europe. It wasn’t until William Gilbert’s work De Magnete published in 1600 that the earth’s magnetic field was understood in broad terms, and recognised as not aligning with astronomical definitions of direction – the magnetic North Pole is hundreds of miles from the point where the earth’s rotational axis surfaces in the Arctic. The difference becomes important for longer voyages.

From a religious point of view the east was initially important as the location of the rising sun, and represented birth with the opposite direction, west, representing death and sometimes rebirth. The Jewish faith, Christianity and Islam tried at the beginning to break this link to distinguish themselves from earlier sun worship but in the end succumbed to the east being a special direction. Christian churches have long been oriented with the altar at the east, and burials with the head to the west. In Islam the great expansion of the Islamic Empire was along the North African coast which meant praying in the direction of Mecca meant facing east. Geographically medieval maps of the world placed the east at the top. Mercator placed the north at the top of his 1569 map of the world but this seems to have been more a convenience than a matter of principle for him. He was mapping primarily for east-west journeys which fit better with north at the top.

North and south do not appear to have had strong religious connotations, culturally their meaning varied over time. The south represented unbearable heat from the point of view of ancient Mediterranean civilisations and the north every increasingly harsh conditions with fanciful notions as to what happened at the North Pole (which continued through to Mercator’s time at least). Later Thomas More and Francis Bacon would locate their Utopias in the far south.

These days North, South, East and West all have strong political meanings although these vary with context, in the UK the North has been associated with poverty, depravation and decline whilst in the US and Italy the opposite is true. On a global scale we talk about the wealthy Global North and the developing Global South. The West has long been a place of political aspiration, the East represented the old Soviet Union and Japan.

For me the biggest idea in this book was think of the compass beyond physical direction, it also provided a handy supply of pub quiz facts all in all a short yet thought provoking read.

Book review: A History of the World in 47 Borders by Jonn Elledge

My next review is of A History of the World in 47 Borders by Jonn Elledge. This is a collection of 47 chapters on different aspects of geographic borders. The book is divided into three parts, the first “histories” talks about borders through history, the second on “legacies” is about borders we see today – often the unusual – and how they came to be. The final, shorter, part is on “externalities” – on borders in the air, sea and time. The chapters are standalone so its easy to dip in and out – if that is how you prefer to read – it makes reviewing more difficult since 47 separate stories can’t be summarised in a short blog post.

The histories section starts with the border between Lower and Upper Egypt which dates back to 4th millennium BC. We know this was a border because ancient Egyptian records reference kings of the Upper and Lower Kingdom. Ancient Egypt was divided into administrative regions called “nomes” – like counties – which persisted for the enormous period of 3200 years until the Muslim invasions of 640CE.

It was a revelation to me how recent the idea of a modern nation state is – really just the last 300 or so years, and how the world was not neatly tessellated with states until quite recently. To be fair there are sufficient border disputes to argue that the world is not neatly filled now. The Peace of Westphalia in 1648 is often seen as the birth of the modern nation state – although the written agreement is rather thin on details. The rise of the modern state was a combination of political developments but also improved mapping from the 16th century – accurate mapping being a pre-requisite for establishing borders.

I was excited to learn of the Marcher Lords and the origins of the Marquis title; the Marches are border areas whose lords were given greater flexibility in, for example, raising an army, in order to defend borders. Marquis is the French term for such a lord. The ability to raise an army is a risk to the state – as the Roman Empire discovered on several occasions.

The legacies section talks about interesting borders in the present day. I think my favourite is on the borders in Baarle-Hertog and Baarle-Nassau – a Belgian town surrounded by a Dutch one, as a result of the Holy Roman Empire and various feudal lords. It isn’t even as simple as a single boundary – there are something like 30 parcels of land in the town, some as small as 50 metres on a side. There are also a couple of German and Italian towns embedded in Switzerland.

This section also contains stories of accidental invasion, the most benign of these are the Swiss “invasions” of Liechtenstein. These are generally because the border is heavily forested in places and there is no indication on the ground as to the location of the border – these have happened repeatedly in the last 50 years. Other borders suffer more fractious disputes – the Cambodia-Thailand border dispute is in the news as I write.

Bir Tawil on the Egypt – Jordan border is an area the size of Surrey claimed by neither state because to claim it would mean giving up claim on a more lucrative piece of nearby land. This is one of many places where post-colonial borders – often drawn along lines of latitude or longitude – have led to problems in the present day. This is partly because they paid no attention to features on the ground but also because, at the time they were set, the precision with which longitude could be measured was not that high.

Surprisingly this also effects the USA, where in addition to lines of latitude and longitude treaties often contained later-to-be-discovered-vague geographical references. I read a whole separate book on the borders of the US states. The origins of the District of Columbia, where the US capital sits are also discussed – originally this was a square plot of land demarcated for the capital so that no state had an advantage in the federal government, later it lost the land on one side of the Potomac River. In the modern era this has led to an anomaly where the many residents of the capital are democratically under-represented – they only gained a democratically elected mayor in 1975.

The externalities section covers the prime meridian – where the zero for longitude is set, time zones, the international date line, Antarctica, Eurovision, various landlocked countries, maritime boundaries and boundaries in the air and space, or rather the boundary between air and space. It is eclectic, to say the least. I found the chapter on maritime boundaries particularly interesting – I was surprised how recently the law on territorial waters came into force (1994).

This made good holiday reading, it is written in an engaging style and chapters are of a handy length to read sitting in the garden in an hour or so. The sources and further reading section is excellent if you want to learn more about any chapter.

Postscript: I made a note to myself that Aboriginal and Torres Strait Islander Australia map of Australia was not reproduced in the book, so I link it here. To be fair it would not reproduce well in black and white at the scale of the book.

Book review: Hidden Histories by Mary-Ann Ochota

For my next book I read hidden-historiesHidden Histories: A spotter’s guide to the British Landscape by Mary-Ann Ochota. As a countryside walker and cyclists of many years, I’ve always been interested in what I saw and how it came to be, Hidden Histories is just the book for me.

The book is divided into broad sections: lumps and bumps, stones, lines and "in the village" and within each of these sections there are 10 or so topics covered over a few pages each. There are many illustrations, and photographs on pretty much every page. Domestic buildings and churches are covered but castles and stately homes are not which is not unreasonable.

If there is a gap it is in the coverage of industrial landscapes which is limited, this reflects my interests and where I have lived, and holidayed, as much as anything.

"Lumps and bumps" covers long barrows (collective burials dating back to the Neolithic), round barrows (single burials, found in nearly every parish dating back to the Bronze Age), hillforts (defensive earthworks from the Iron Age), miscellaneous earthworks and the ridge-and-furrow plough system. I was interested to learn that windmill bases can be mistaken for round barrows. One learning of this section is that there are only known burials for about 10% of the estimated population of prehistoric Britain. I grew up in Dorset which makes frequent appearances in this part of the book. Maiden Castle was a regular walking spot – it is the biggest Iron Age hillfort in Europe.

The ridge-and-furrow plough systems makes a re-appearance in the section on lines. Essentially visible ridge-and-furrow systems are usually at least seven centuries old and are the result of the medieval method of farming with ox-drawn ploughs which leave a shallow S-shaped furrow. This gentle S-shape is also seen in ancient field boundaries. The way land was owned and shared is also relevant, in medieval times land was common with patches exploited by individuals but individual plots did not have hedge boundaries. This ended with the Enclosures Acts in the 18th and 19th century that made land ownership more individual although in principle it shared land equitably in practice it favoured the rich who had the resources to exploit land in line with the new Acts. Enclosure Acts were particularly important in the Midlands and had widespread impacts on both people and the landscape.

"Stones" covers standing stones, stones in circles,stones in lines, stones with symbols on them, stone crosses, stone tools and wayside markers (stone ones!). Standing stones are difficult to date, and Stonehenge is pretty unique in that its constituent parts are not local, usually stone circles are built from local stone.

"Lines" talks about Roman roads, and other ancient pathways before moving on to the shapes of fields and various chalk figures. I grew up just down the road from the impressive Cerne Abbas giant which is 2000 years old, there is also a white horse on the hillside into Weymouth but that is of George III and dates back to 1808. I hadn’t appreciated that chalk figures require very regular maintenance which is impressive considering the Uffington white horse dates back to 1400BC.

Holloways have a number of mentions – these are ancient routes that have been worn below the prevailing ground level by use. It is chastening that after the Romans left their road building skills were not surpassed until the turnpike roads were introduced a thousand years later.

"In the village" covers various buildings found in villages, mainly houses and churches but briefly mentioning pubs and barns. The age of homes is of direct professional interest for me, although the focus of Hidden Histories is older buildings. I was bemused to learn that the term "Gothic" was originally applied as an insult coined in the 1600s to describe what they saw as overly ornate buildings from the 1200-1500s.

I learnt a wide range of useful facts from this book, such as "metalled" roads being derived from the Latin for "quarry" which has always puzzled me! I also learnt that "turbary" refers to peat workings, so I have learnt a new word to slip into conversation.

I’m interested in maps and computers so it struck me there are some interesting things to do in geospatial analysis relating to this book. For example, medieval ridge-and-furrow ploughing shows up quite nicely in LIDAR, as do other earthworks. Similarly field boundaries and place names, and other mapping features, are all in Ordnance Survey mapping products and these days are readily accessible by automated means.

Cheshire, where I live now, has few entries although on this morning’s cycle I was spotting what I now know to be Enclosure Act hedging with oak "standards" spread along it. Hidden Histories satisfies a curiosity I’ve always had about the countryside I’ve been traveling through.

Book Review: History of Britain in Maps by Philip Parker

history_of_britain_in_mapsI’ve always been a fan of maps, so the History of Britain in Maps by Philip Parker is right up my street.

The book is ordered chronologically with each map getting a short page of text facing a page of the map, with some maps earning an additional double page spread. Except for the earliest periods the maps are contemporary.

The book has the air of written as a set of separate map captions with some repetition between maps relating to the same period.

There are some recurring themes through the book, maps for the pleasure of maps seem to play a role, as do military maps showing defensive positions or explaining military actions. Maps of ownership are also common. Finally there are maps for travel, first by road and then later by canal and railway. Also apparent is the evolution of mapmaking skills.

Aside from the exceedingly schematic representations of Britain on the Roman Rudge Cup from 130AD the earliest maps of Britain date to the medieval period and Matthew Paris, a Benedictine monk who was active around 1250AD. There are religious Mappa Mundi from slightly earlier but Britain is very much on the edge of these schematic representations of the religious world with Britain perched at the very edge, if visible at all.

The earliest map of Britain that looks like a map is Matthew Paris’s map of 1250AD. The shape of coast is heavily distorted but some names recognisable to the modern eye appear (such as my home county of Dorset). Rivers are prominent most likely because they were the key method of transport over longer distances. There is a strand of maps that portrays the nations of the British Isles, the counties within them and cities, particularly London which are about place, belonging and power rather than navigation or even defence. Towards the end of the 16th century such maps start to look very much like modern maps, they are relatively accurate and follow modern mapping conventions (rather than being panoramic views or schematic views).

Also produced by Paris is an "itinerary map" showing the progression of towns a pilgrim to the Holy Land would pass through on their trip from Britain. This type of map is a recurring theme through the book, it is not interested in the details of the landscape, it is not a plan view, it is a linear track with distances. This is highly relevant to the traveller who is constrained to travel along the roads rather than view the landscape from above, as a bird does. In some respects this path turns full circle with Beck’s highly schematic but very clear London Underground map.I was interested to learn that road signage was not introduced until 1696.

Although there are earlier examples of coastal maps Henry VIII’s dissolution of the monasteries in the 16th century which led to open season being declared on Britain by the Pope, produced a number of coastal maps of the South of England. These are a recurring theme. The monarch, and his counterparts in Europe, were both keen to map the defences of the South Coast. Similar maps were produced during the Napoleonic Wars and the Second World War. Also falling into the military remit are the various maps of military engagements of the Civil War. The earliest work of what was to become the Ordnance Survey in Scotland in the mid-18th century and then in Kent related to military interests (the clue is in the name).

Maps of ownership are another recurring theme, these start in the early 15th century typically establish the land and rights of the monasteries. Later maps, in the early 19th century, show the results of the Enclosure Acts which took from Common land from everyone and gave to the wealthy now-landowners. Similarly the tithe system whereby a tenth of the produce of an area was owed to the parish was converted to a land taxing system where money was given instead.

There are the 19th century "social" maps of cholera by Jon Snow’s, deprivation by Charles Booth and the census of 1841 by August Petermann. Fi

The book ends with a map of the votes cast in the 2016 EU referendum, a bitter topic as I write in January 2021. 

Obviously as a fan of maps, I enjoyed this book. It is a nice skim through British history if you don’t want anything too heavy going, it is also a good overview of what types of maps people were making and when. I’d seen quite a few of the maps shown in other books, you can get a flavour of these here on the maps tag of my blog.
