Mapping radiation

On the 26th April 1986 technicians at the Chernobyl Power Plant in the Ukrainian SSR turned off the power to the number 4 reactor, hoping to test back-up generators used to keep the cooling waters circulating in case of a power outage. During the test the power-levels dropped to unexpected and dangerous levels. Following instructions that didn’t allow for such a possibility, meant that the test proceeded, leading to a chain reaction releasing a huge amount of energy which immediately vaporized the cooling water, caused a devastating steam explosion and then the escape of a large radiation cloud. Wind conditions and proximity to the site meant that most of this radiation fell on the Byelorussian SSR.

This map, made post-independence in 1992, shows the density of pollution caused by Caesium-137 at different levels of contamination (a radioactive isotype that reacts with water, which as a consequence makes it easy to move around the body. It is one of the two most prominent isotypes released after the accident, and will continue to be a major health hazard in the area for the next two hundred years). The strong use of colours, more reminiscent of coloured-layering, is here used to show dramatically the area of contamination. There is also an inset of the area nearest the nuclear site showing strontium and plutonium radiation (Chernobyl is at the bottom centre of the map, Черновыль). What the map doesn’t show, of course, is the human cost to this tragedy. Only the title, ‘…until January 1992’, hints at a lethal problem still in place 6 years after the event. An updated version from 1993 manages to convey this cost though. Text in a number of languages states ‘…a catastrophe broke out – the major break-down of the power unit at the Chernobyl Nuclear Power Station. By its scale, complicity and long-term consequences it is the most severe catastrophe throughout the entire World history of atomic energy use…after the Chernobyl accident Belarus has become the zone of of the ecological disaster‘.  The text is in a number of languages; Russian, English, French, German and Polish, and when you carry on reading you realise why. As well as a map to show the spread of radiation following the accident the map is also a plea for international aid, ‘But the extent of the consequences of the catastrophe of the Chernobyl Power Station is so enormous that, it is regrettably, impossible for Belarus to liquidate them alone. The Republic badly needs medicines…The Byelorussian people, guiltless victims of the severe catastrophe, need the help of the international community.’

This extract comes from the back of the 1993 map, which includes the appeal for international aid. The three maps show the spread of the contaminated cloud between the April 27 and May 1st.

Maps have played a crucial roll in showing the aftermath of the Chernobyl incident. From tracking the contaminated cloud spreading across Eastern Europe to the more long-term mapping of contaminated lands maps have been the most useful medium to show the immediate and long-term effects of the disaster.

The Bodleian holds maps from the International Atomic Energy Agency, the Office for Official Publications of European Communities and the Hungarian Academy Research Centre for Astronomy and Earth Sciences as well as commercial publishers on Chernobyl and there are a number of interesting websites on the disaster, including Chernobyl Exclusion Zone Map – Chernobyl 35 years laterNew mapping of radioactive fallout in Western Europe | EU Science Hub ( and  ESA – Mapping Chernobyl fires from space

How to make a map Soviet style

On the reverse of a map of Minsk from 1991 there are some interesting and unusual sections. As well as including instructions on measuring distances there are also examples of the same area at different scales (1:1,000,000 going down to 1:10,000 and centring on the village of Borovsty). Shown here are the 1:1,000,000, 1:500,000 and 1;200,000 scale maps as well as two pictures about orientation


Map reading instructions and examples of different scales aren’t uncommon features, what makes this particular map stand out is the little diagram showing the process of making a map, from planning (ПроеКт) through surveying (aerial as well as ground-work) to drawing


and production and finishing with sales. Can the whole exercise be included as proof that the Soviet system still worked despite the Union breaking apart?, the Byelorussian SSR itself declared independence the same year the map was made, becoming Belarus.

The end result of all this work is the main map, made by the Soviet Cartographic Department, the Glavnoe upravlenie geodezii i kartografii, more commonly known as the GUGK (Main Directorate of Geodesy and Cartography). The use of oranges and greens here is a common feature of Soviet maps, immediately recognizable as a product of the GUGK.

Field patterns

Recent work on the Laxton map reminds us how beautiful maps often are, but also how beautiful the patterns made by field systems can be as well.

The central part of the Map of Laxton, 1635, MS. C17:48 (9)  (see notes at end for more information on Laxton)

Fields are a natural part of the landscape, but the dating of the fields can vary greatly depending on where you are. Areas of the West Country still have what is called Ancient Countryside, fields and farm land untouched by Enclosure acts. Fields at the tip of Cornwall on

the Penwith Peninsula are thousands of years old, a crazy pattern with small fields and many angles, utilizing boulders in the landscape too big to move or pre-existing ancient monuments such as standing stones and burial chambers. Due to the construction of these boundaries they are hard to move or alter, and it’s because of this that these field boundaries are, despite their age, still in use today. This type of landscape can also be found in areas as diverse as the Welsh borders and Essex, Sussex, Kent and Surrey. This extract comes from the 2nd edition Ordnance Survey 6 inch map of Cornwall, sheet LXI S.W., 1908. The Ordnance Survey shows fields up to and including maps at a 1:25,000 scale.

Laxton is an example of an Estate map. These are almost always manuscripts, with a cartographer commissioned to survey and produce a map with details such as field size, use and often details of individual field ownership.

Being a one-off often led to a beautifully illustrated and informative map. This example shows the  fields surrounding the Down Hall Estate in Essex (MS C17:28 (38), 1718), and was surveyed by William Cole, who was also a schoolmaster in Colchester. Down Hall Estate (home of Bake Off no less) features in the middle of the map, with details of the kitchen gardens surrounding the house.  Further examples of estate maps can be found here and here

One of the best maps of Oxfordshire, Richard Davis’s map from 1797, falls in-between the old practise of open fields and the new approach, that of Enclosure. This sheet shows the area to the East of Oxford (the county boundary followed the Thames until the 1970s) and has both big open fields and the new, smaller, patterns in place. The map shows the start of a new type of landscape, called Planned Landscape, neat fields with straight lines, without any of the quirks found in older field patterns, which often followed ancient parish boundaries and streams.

with an extract here

A new map of the County of Oxford : from an actual survey; on which are delineated; the course of the rivers and roads, the parks, gentlemens seats, heaths, woods, forests, commons &c. 1797                C17:49 a.1

This blog has been partly inspired but a recent series of programmes on the BBC called Winter Walks. Over 5 episodes people such as Simon Armitage, Baroness Sayeeda Warsi and the Rev. Richard Coles have walked in Yorkshire and Cumbria, holding a portable camera and accompanied by a drone giving aerial views of the incredible landscape and field systems on show. These field patterns can be seen in this Ordnance Survey 3rd edition sheet of Grassington (Yorks CXXXIV N.W., 1910). The field boundaries shown on the map would have been efficient way of using up stones found in the fields when ploughing. Dry-stone walling would also have the benefit of letting the wind through, reducing damage.

Be it from drone footage or walking in the country-side field patterns are revealed as objects of beauty as well as important agricultural features. They are also a chance for us to show off more beautiful maps from the collection at the Bodleian.

* The Laxton map, A Plat and Description of the Whole Mannor & Lordship of Laxton with Laxton Moorehouse in [y]e County of Nottingham and also of the Mannor & Lordship of Kneesall Lying Adiacent to [y]e Aforesaid Mannor of Laxton,   measures 178 x 203.5 centimetres on 9 rectangular pieces covering the villages of Laxton and Kneesall, around a dozen kilometres northwest of Newark-on-Trent. Dating from 1635. Approximately 3,333 separate field strips are shown on the map, which is made from sheep-skin. The area is still farmed using the open-field system, incorporating crop rotation, though to a lesser extent than at the time of the map.                           The Map Librarian at the Bodleian, Nick Millea, talks about the map here


Today is Thanksgiving, celebrated in the United States and Brazil on the 4th Thursday in November (Canada celebrates on the 2nd Monday in October with a few other countries throughout the World using either of these or dates around these days as well). Thanksgiving is a harvest based celebration, and, more importantly here, is also connected with early English settlements in the United States. It’s a chance for us a post a blog featuring one of the treasures of the Library, John Smith’s beautiful map of Virginia, dated 1612.

Smith was Governor of the Colony of Virginia and one of the founders of Jamestown, the first permanent English settlement in the United States. Smith’s map is orientated with west at the top, the best way to represent on paper this elongated stretch of country. The Chesapeake Bay is the horizontal stretch of water just below the centre of the map with Jamestown, in red, on the Powhatan (now called the James) River. Smith shows the areas both explored, often by himself, and unexplored, using crosses on the rivers to show the limits of European knowledge. Most striking though are the images of Native American life, on the left is a scene showing the local chieftain Powhatan and members of the Powhatan tribe while on the right is a Native American with the inscription ‘the Sasquesahanoughs are a gyant like people & thus a-tyred’. Maps played a crucial role in the early history of the United States. Dutch, English and French interests in territory made the setting down of ownership and boundaries on maps and documents a way of establishing claims and legitimacy to land which would go on to play a crucial role in the way the early history of the country developed.

This map comes from a book Smith wrote about his time in Virginia, called ‘The First Booke of the First Decade contanying the Historie and Travaile into Virginia-Britania‘, and came to the Bodleian from the collection of Elias Ashmole, founder of the Ashmolean Museum. Ashmole had donated his collection to the Ashmolean in 1677, this was then passed onto the Bodleian in 1860.

Measuring distances, a wheel or a chain?

John Ogilby has to be one of the most interesting of all the cartographers. Before turning to making maps aged 66 he had at various times been a dancer and dance instructor, theatre manager and publisher, with career changes usually the result of misfortune of some kind. His dance career ended after suffering serious injury during one performance, his career in the theatre in Dublin came to an abrupt end due to Irish rebellion against the English in 1644 and then finally he lost most of his publishing stock in the Great Fire of London.

It was the fire that set Ogilby on a new path as a cartographer. After mapping the devastated city to aid in redevelopment Ogilby embarked on the project that would not only give him lasting fame but introduced a new way of mapping  roads. In 1675 Ogilby published the Britannia, an atlas of 73 routes at a scale, for the first time, of one inch to the mile (1:63,360). As can be seen from this example Ogilby revolutionized the way maps were shown by only focusing on the relevant information for the road user and by making the best use of space while creating maps full of useful information and easy to understand.

Miles are marked on the road maps with furlongs in between the miles shown by dots (a furlong being the length of a furrow in a common field, by Ogilby’s day there were 8 to a mile). Compass roses show north and hills are drawn in a way to show if you are travelling up hill or down. The cartouche includes figures surveying and using tools that would have been used to map out the route and recorded the miles.

The wheel on the end of the stick was called a way-wiser that recorded each turn of the wheel on a dial,  while underneath that a winged figure called a Putto is using a Gunter’s chain, invented in 1620, which was laid along the ground to measure distances. The chain measured 66 feet divided into 100 links, ten chains length was a furlong, 80 a mile.  The figure on the horse is holding a compass.

Ogilby died the year after the publication of Britannia, but his work stayed in print, first through the efforts of his step-grandson William Morgan (who like Ogilby was appointed ‘His Majesty’s Cosmographer’), and then through, acknowledged or often not, the works of later cartographers, all making use of such a rich and inventive source of information.

There is one more intriguing chapter to the story. Ogilby was closely allied with Charles II, and there is a theory that Britannia was published to help with a proposed invasion from France to restore the Catholic faith in the country. For some the emphasis that Britannia places in routes to poorly populated ports and locations in Wales and the West Country and the publication date being so close to a signing of a secret treaty with France (so secret it didn’t come into public knowledge till 1820) shows that this was a road map with a hidden agenda, and it is only with this agenda in mind that some of the seemingly random things shown on the maps; a house in the middle of nowhere, mines in one location but not others for instance, begin to make sense.

In the corridor outside the Map Office here at the Bodleian nine portraits are hung. Two are of cartographers; John Speed, the famous Tudor map maker, and John Ogilby, both of whom originally were named in their picture. Ogilby’s name has at some point been painted out, this may be due to changing fashions as none of the other, later, seven portraits name the person in the picture. We can’t be sure though if his name has been erased deliberately, another layer of mystery attached to a man who had more than his fair share throughout his life.

Treasure Unearthed!

Shelf checking a printed book collection I came upon an uncatalogued atlas which looked very interesting.  Although it had engraved and letterpress title pages for Visscher’s Atlas Minor it was, in fact an atlas factice of mainly seventeenth century maps from atlases of various publishers. It is contained in the Bodleian’s collection of books belonging to John Locke (1632-1704), philosopher and influential Enlightenment figure.

Locke was awarded his master’s degree from Christ Church, Oxford in 1658 and developed into polymath and in 1668 was elected as a Fellow of the Royal Society but his interests also covered amongst others medicine, political theory and religious tolerance and influenced by Bacon, Descartes and Hobbes.  Throughout his life he wrote and disseminated his ideas on this range of subjects so it is no surprise that he would have amassed a collection of maps.


After his death in 1704, his library was left to his cousin Peter King, later Lord King when in 1947 the Bodleian bought some of the books and manuscripts. The remainder were found at Ben Damph Forest, the seat of the Earl of Lovelace (as Lord King later became) and were later bought by Paul Mellon who then presented this collection to the Bodleian in 1978.


The volume itself contains 48 maps, charts and plans produced and published by the leading cartographers contemporary with Locke, so along with Visscher, Frederik de Wit, Carel Allard and Peter Schenk also featured.  Additionally included is an ephemerides by Jean Baptiste Coignard which would have sat well with the maps. Map number 15 A New Chart of the Sea Coasts Between England and Ireland by Richard Mount is uncommon and unusually oriented with west at the top.

The binding is the original vellum with blind stamped border and corner pieces; and large ornament with evidence of ties. There is a spine title in manuscript (Locke?) Visscher Atlas. There is a circular red morocco bookplate with a gilt image of stook of corn and lettering “Oak Spring, Paul Mellon” indicating its later provenance.

To the readers hello

This remarkable early example of a town plan shows the French port of La Rochelle under siege in 1573.

During the French Wars of Religion La Rochelle had become a centre of Huguenot support, and was besieged by troops loyal to the Catholic Duke of Anjou. The siege was lifted in the year the map was made and La Rochelle became one of the few cities in France where Protestants were allowed to worship.

In the box in the top left, ‘Aux lecteurs salut’ (To the readers hello) the cartographer first claims he has made this map to meet the desire of the most curious, and then sets out what his map shows; the defences and how the rebels holding the city were besieged both from the land and the sea, the damage caused within the walls and the names of locations. The text ends by stating that the Royalist forces did not spare any lives or goods in order to deliver to the King victory, though the siege was lifted in June 1573 without outcome. The brief publishing information at the bottom of the map is intriguing. The text tells us it was made by F. Desprez in the Rue Montorgueil, Paris, there is then the words ‘au Bon Pasteur’ (the Good Shepherd or Pastor) which may relate to the fact that Desprez worked close to the Church of Saint-Eustache.

The map clearly shows the formidable fortifications La Rochelle had, full of thick and angled walls designed to deflect cannon fire and force attacking troops into narrow spaces easy to attack from the walls. More on this type of fortification and the beautiful maps that show them can be found here

The map publication date of 1573 means it is a very early example of a town plan held in the Bodleian. The earliest for Oxford is from 1578 (Ralph Agas, see an image here,). For London 1572, a map that comes from an atlas of town plans called Civitates Orbis Terrarum, an earlier blog post gives more information about this celebrated atlas here

Why some maps lie and how they do it

Maps are 2-dimensional representations of a location, created by a cartographer, editor or publisher. Most are straightforward in that they portray accurately (hopefully) that area covered. Occasionally they mislead, either accidentally or deliberately. A misleading map played a part in one of the most famous and important events in World history. Christopher Columbus’s decision to sail west to reach the East Indies was partly due to a map in an atlas of maps by the Classical cartographer Claudius Ptolemy (c. 100-170). While this map was the most up to date

based on contemporary knowledge it  missed parts of the Earth as yet undiscovered by European explorers. Without the knowledge of a whole new continent in the west Columbus set sail hoping to find a new and quicker route to the East Indies but instead discovered the New World ( To read more about how the Bodleian’s copy of a Ptolemy atlas has an amazing connection with Columbus click here).

Another  intriguing example of misleading cartography is the representation of ‘Phantom Islands’ on maps. These are islands which for a number of reasons; low cloud, recording already surveyed locations as ‘new islands’  and mirages have all been the cause in the past, are mapped and then continue appearing on maps as cartographers use old information, until a new survey is made or a ship reports that the island doesn’t actually exist. The inset on the right is of a map made in 1710 of South America which features Pepys Island, named after the famous diarist who was also the Secretary to the Navy. Lying off the coast of Argentina  and first recorded in 1683. Pepys Island was shown  on maps for over 150 years until 1839, when was finally proved not to exist. This extract is from South America corrected from the observations comunicated to the Royal Society’s of London & Paris… by John Senex, which featured in a blog here

These are just a few examples of how maps can, without meaning to, lie (or, to be fairer, give incorrect information). There are a number of examples though of publishers deliberately making mistakes on their maps. Soviet-era maps intended for Western visitors were often  misleading to avoid Western states having accurate mapping of Soviet cities and towns. Some commercial publishers include false information amongst their maps to catch competitors out who have copied work without acknowledging or seeking permission, This is more common on street atlases, which is why the these false inclusions have the rather wonderful name of ‘trap streets’.

The reason for this long preamble is that, like other colleagues in the Map Room at the  Bodleian, i’ve spent a good part of the lockdown going through scanned images in folders and recording shelfmarks and other details (see the blog ‘Rummaging through virtual maps’ directly below). My work has involved working through the Bodleian’s trench and other maps of the First World War. These are amongst the most evocative of all the maps in the collection, full of names that for anyone interested in history are instantly recognizable; Mametz Wood, Passchendaele, the Somme, Messines and Vimy Ridge.  These are maps made for, and used in, the planning and carrying out of operations that in some cases cost the lives of thousands while making miniscule gains in land. But the reason for including these maps in this blog is that the more detailed trench maps, at 1:10,000 and 1:20,000 scales, ultimately, but necessarily, lie. For example take this extract of a trench map covering the French city of Lens.

The red lines to the right are the German front-line and support trenches, the blue lines are the Allied trenches (most trench maps only show the Allied front-line, it’s not often that you have so much Allied trenches shown in case the map was captured by the enemy). These trenches, the information relevant for the December 1917 date of the map, are overlaid onto a pre-war map showing what looks like a normal French city with railways, roads, houses and churches. In reality the city had been heavily bombed during the War with most of the buildings levelled, and the trenches were made out of the rubble caused by bomb damage.

A better example of the contradiction between map and ground can be achieved by comparing this map covering Chateau Wood with a photo of the same area. Chateau Wood is east of the Belgian city of Ypres and had been behind the German front-line until Allied advances towards the Passchendaele Ridge in the Third Battle of Ypres in 1917.

Hooge, 3rd ed, 1917. C1 (3) [1973]

 On the trench map the Wood has  field boundaries and tracks through the trees (Chateau Wood is east of Hooge in square 13, and can be seen in this extract). Compare the calm and ordered landscape portrayed on the map with the reality on the ground from this photograph of duckboard tracks going through the wood taken in October after advanced beyond the wood and beyond towards Passchendaele.

Ultimately though how do you map land like this which has had all recognizable features long-since destroyed and ground constantly altered by artillery fire? During major battles maps were produced on a regular basis to keep as up to date as possible with an ever-changing front-line, hard enough to do if just mapping the new positions of trenches, impossible to complete if you mapped each new shell crater or destroyed pill-box. To have vital and ever-changing information such as trenches and enemy positions printed over a landscape that was no longer there but was shown on pre-war mapping was, with the need for accurate and quickly produced maps, the only option, but by necessity a lie.

The Devil’s what?

Herman Moll (c1654-1732) was a cartographer  who moved to London from north-west Europe in 1678. At first Moll worked for other established mapmakers as an engraver before setting up his own workshop making and selling maps. These images come from one of his most celebrated works, ‘A set of fifty new and correct maps of England and Wales’* published in 1724. The Bodleian has a number of copies of this work, some of which were in black and white with others hand-painted, these images come from one of the black and white editions.

Oxfordshire has two illustrations for Blenheim Palace, completed two years earlier in 1722, and one for the Rolle-Rich Stones (Rollright Stones), built considerably earlier at some point  between 2670 to 1975 BC. For those familiar with the Rollrights this is an image before restoration in the late 1800s which replaced a lot of stones broken up from the original circle, increasing the amount of stones in place. Next to the Rollrights is a mosaic from a Roman villa north of Woodstock.

One of the stranger illustrations found on any of the county maps is from the the West Riding of Yorkshire page, of the Halifax gibbet, which promises ‘according to the Halifax Law whereby they beheaded any one instantly‘. A ruling (the ‘Halifax Law’) that allowed the Lord of the Manor to execute thieves by beheading had been in place since the 1200s, and the gibbet was Installed at some point in the sixteenth century. A large number were executed under this law but it isn’t known how many were executed using the gibbet, which was dismantled after the the last executions in 1650 under instruction from Oliver Cromwell.

Moll had an obvious love of anything old, his county maps are filled with portraits of antiquities around the margins, and on his title page a note promises ‘to render this work more acceptable to the curious, the margins of each map are adorn’d with great varieties of very remarkable antiquities’. Roman coins and fossils, given all sorts of weird and wonderful names, feature prominently. On this half page of Wiltshire two views of Stonehenge are given. Both are a relatively accurate portrayal, something that earlier cartographers such as John Speed, hadn’t done, setting the great circle in mountainous countryside and making the stones look tubular (extract from Wiltshire, John Speed, facsimile (E) C17:61 (49), original map 1610).


This last page is a map of the county of Derbyshire, parts of which have an underlying limestone bed, leading to numerous cave systems.

The Devil’s Arse is more commonly known now as Peak Cavern.

There is little in the maps in Moll’s book that make them any more special than similar atlases printed at the time. Few roads are shown, though those that do have distances between towns marked, and boundaries of the county hundreds are set out. What makes Moll special is the illustrations, historical portraits made to appeal to both the armchair traveller and any with an archaeological and scientific interest giving an idea of the unique features found in each of the counties.

*The full title is A set of fifty new and correct maps of the counties of England and Wales, &c. with the great roads and principal cross-roads, &c. Shewing the computed miles from town to town. A work long wanted, and very useful for all gentlemen that travel to any part of England. All, except two, composed and done by Herman Moll, geographer.

Sending cabbies in circles

Joachim Friederichs map of London takes an interesting approach to measuring distances. A series of circles covers the whole map, each one representing ½ a mile in diameter, making it possible, according to the cartographer, to ‘merely count the number of circles between one point and another you have at once the distance travelled’.

The Circuiteer, or distance map of London: invented by J. Friederichs, particularly adapted for cab conveyance c1850. (E) C17:70 London (359)

Measuring distances in maps is a long established practice; from simply putting in distances along roads from point ‘a’ to ‘b’ to concentric circles at a set distance radiating out from a central location to the scale bars and grids so familiar to us from our Ordnance Survey maps. With so many maps of London published Friederichs map stands out with it’s unusual approach.

As well as a distance guide the map serves as a proposal to right what the author sees as a serious case of wrong-doing, the over-charging by Hackney Carriage drivers. In text accompanying the map Frederichs writes ‘The monstrous imposition practised by Cab-Drivers upon the public have long been the subject of general complaint, but of all the plans hitherto suggested to remedy the abuse – and they have been many – not one has been found to ensure. The purpose the Circuiteer, or Distance Map, at least offers  a certain protection against such extortions, as the reader will be enabled to judge for himself, from the following concise explanation.’

The text goes on to give examples of proposed fares, considered reasonable, by mile as opposed to by route, and suggests the buying of pre-paid tickets instead of paying cab fares.

Hackney Carriage fares have featured on numerous maps of the City. This example, A new and exact plan of the cities of London and Westminster & the Borough of Southwark…whereunto are added the rates of Hackney Coachmen and watermen with several other embellishments. By Robert Sayer, 1775. (E) C17:70 London (72),  has, as well as a wonderful map of the City, a small box in the bottom corner giving a ‘Table of Rates’ at both a shilling and eighteen-penny and rates for the Thames watermen. The map also has insets of the major buildings and shows the Ward boundaries.
