Parallax is a way of determining distances and heights by measuring the angles of a certain point from different locations. Once you have the angles from two points you can then work out the distance by working out the third angle of a triangle and measuring the sides. Amongst other uses parallax is the method in which the distance to stars is measured.

Parallax is also the title of a recent donation to the Map Room, Parallax without tears, the determination of heights from vertical airphotographs

First World War mapping and the Bodleian

Trench maps are an important source of information regarding topography, defences and changes in the position of front-lines in the First Wold War. They are also, for those looking back at the war from the distance that 100 years brings, a stark representation of how close enemy forces were to each other. Detailed maps such as the one shown here reveal a no-mans land often less than 100 metres across. At first maps were based on existing French and Belgian pre-war sheets, but problems with marrying up scales and grids used on these sheets meant that by late 1914 the War Office and the Ordnance Survey took over production of trench maps, and from then until the end of the war a large number of sheets of different scales and designs were published to meet the varying demands of the British Army.

The development of trench warfare in late 1914 meant a fairly static front-line position. This, along with increasing importance in the use of artillery, led to both a need for accurate mapping of enemy positions and the time in which to produce the maps. Trenches that did not move and positions that stayed stable for months at a time meant that surveying, mainly by aerial observation and photography, produced maps that were often available before any changes in territory held made them obsolete, though this was not always the case during the major offensives launched later in the war. For instance, a map produced by the War Office for the Passchendaele area went through 9 different editions during the 3rd Battle of Ypres between July and December 1917.

Fonquevillers, 57D N.E., sheets 1 & 2 (parts of), G.S.G.S. 3602. 1917. C1 (3) [1449]

The map featured here, sheet 57D N.E. parts 1 & 2, is one sheet in a large series covering the Western Front in great detail, at a scale of 1:10,000. For security reasons only the front-lines of the British trenches are shown while the full scale of the German trenches are clearly defined in red. Grid numbers and then numbers in circles at junctions and angles of enemy trenches are for artillery purposes.

Forty-one members of staff left the Bodleian Library to take part in the war. Up until the start of 1917 all were safe but by the appearance of the first issue of the Bodleian Quarterly Review for 1917 this was no longer the case. ‘The immunity of the members of staff on military service from serious injury has been sadly broken by the death of Lieut. R.A. Abrams…who fell while gallantly discharging his duty on the Western Front on March 4 last, aged 28’. Abrams and a fellow solider were reconnoitring near La Brayelle Farm, in between Gommecourt and Essarts on the map, when both were killed by enemy fire. Abrams death in action was followed later that year by a second Bodleian employee, Lieut. H.J. Dunn, also 28, on November the 26th.

A large number of books were produced in the years immediatly after the War by Battalions detailing the part they played in the conflict. The Sherwood Foresters book can be read as a diary of events set down in chronological order and includes plans and photographs


to accompany the text. The above plan shows the area in the Trench map shown earlier and is also mentioned in the previous page in the book with reference to the death of Lieut. Abrams.


As well as British produced maps the Bodleian holds maps by the French and German armies of the Western Front and Allied and Turkish trench maps from the Gallipoli campaign in 1916.



This June marks the 200th anniversary of the battle of Waterloo, fought between the 15th to 18th of June 1815. With the defeat of Napeleon by a combined army led by the Duke of Wellington peace was finally restored to Europe after 10 years of fighting following the French Revolution in 1792.


Bataille de Waterloo. PLan de Champs de Bataille de Waterloo dit de la Belle-Alliance. Victoire memorable remportee le 18 Juin 1815, par les armees alliees sous les ordres de S.S. le Duc de Wellington et de S.A. le Prince Blucher de Wahlstadt sur l’Armee Francaise commandee par Napoleon. Published in Belgium in 1816 and comes with sheet of explanatory text, (E) C28:11 (3)

Waterloo has been mapped a number of times since 1815, the Bodleian shows here just two from a number in the map collection, one English and one in French. Both are laid out in a standard cartographic way of depicting armies and formations by using blocks to represent troop positions (coloured depending on Allied or French), topograhy is presented by using hachures to show hills and slopes and the key places are mentioned. The main difference between the two maps is that the french map, published in Belgium a year after the battle, is of the day and hence has to show troop movements throughout the day, indicated here by broken lines and directional arrows. The later English map, concentrating as it does on a particular and crucial point of the battlet, is less cluttered and easier to follow. Both maps come with accompanying text.


Field of Waterloo, towards sunset on June 18th 1815, from ‘A voice from Waterloo..’ published in 1847. The map shows the positions of the opposing forces as the Prussian forces joined the fight and turned the course of the battle away from the French. The map includes, as well as field positions, an index of the key points and events on the day. (E) C28:11 (1)

Waterloo and the wars fought by Napeleon and the French since 1792 feature heavily in literature such as Vanity Fair  and numerous works by Thomas Hardy and indirectly led to the production of the most successful and long-lived of maps, the Ordnance Survey 1” series. Originally published in 1801 as a set of four maps of the Kent coast made in preparation for the supposed French invasion of England the series continues to this day under the guise of the Landranger series.

Notoriously false

John Pryer’s map ‘A Pocket Companion of ye Roads of the South Part of Great Britain, called England and Wales…’ is not what it first appears. Originally printed in 1724 the map shows the road system of England and Wales giving distances between major towns and cities and is similar to a host of road and travelling maps published around the same time.

Overprinted onto the original map is additional information tracking the path across the Southern parts of Ireland and England of a solar eclipse on the 11th of May, 1724. Given that the map dates from 1724 there is a chance that this map was published after the eclipse to show the route of the shadow of the Sun, not before. Either way this is the earliest sheet map held in the Bodleian to show the path of an eclipse of the Sun.


A Pocket Companion of ye Roads of the South Part of Great Britain…1724. Gough Maps England and Wales 50

Pryer’s map is a copy of an earlier map with the same title by Herman Moll, from 1708. This map went through several editions and was copied, both legitimately and not, a number of times. Moll includes a complaint against copyists in a piece of text on the map

‘Since ye beginning of this new sett of maps now completely finish’d, several ignorant pretenders have started up & with great shew & noise frequently advertised their trifling performances: calling them cheap, curious, useful & correct: as to the first epithet, they are really dear at any price; in ye 2d. place , everybody may see they are wild, confused and poorly engraven; as for their usefulness, they tend only to lead people into errors; and so far from being correct, that the projection of their principal maps is notoriously false’.

It is not recorded whether Pryer is one of Moll’s ‘Ignorant pretenders’, though the lack of any mention of Moll and his map makes it likely that Pryer used Moll without authority. It does bring into question though why he would include the diatribe against unscrupulous publishers and cartographers if he was one himself.

If there is doubt about Pryer and Moll there can be little of Moll’s opinion of one of the most celebrated cartographers of the time, John Ogilby. Ogilby created, with the publication of


The road from Oxford to Salisbury…from John Ogilby’s Britannia, circa 1675. (E) C17 (370)

Britannia in 1675, the first road map of Great Britain, and with it introduced the concept of strip maps. In the legend to Moll’s original map, and kept in Pryer’s reprint, is the following

/ Principal cross roads & many not to be found in Mr. Ogilby’s book

This seems a harsh dig at what was, for it’s time, a revolutionary way of showing main post routes and the level of detail involved was far greater than that of other maps of the time, including Moll. Ogilby’s innovative design included mile indicators, side routes and hills (including showing the direction of slope) and was soon taken up by other cartographers in both this country and abroad.

The Eighteenth Century saw an increase in both the publication and quality of maps such as Pryer’s as the growth in both astronomy and scientific knowledge advanced, and with it the ability to predict and plot each eclipse. Previously eclipses were reduced to diagrams in the corners of world maps, such as the example here from John Speed’s ‘Prospect of the World’ atlas for 1627.

Cartoon maps

2015 is the two hundredth anniversary of the famous political cartoon by James Gillray showing Napoleon and Pitt the Younger carving up the World.


The Map Department holds a number of examples of cartoon or satrical maps. Most are designed with a similar intention to the Gillray, that of educating and entertaining at the same time, the maps are based on geographical boundaries but usually have no other topographic features, and instead fill up spaces with figures. This example, from the start of the First World War, is one of the best of this type in the map collection.

Despite its initial appearances it has a serious message to convey. Germany looks towards France while Austria, dressed as a clown, clings on desperately while watching horrified as the brown bear of Russia grabs at ankles and talons. Britain prepares to stride across the channel to sort out the mess, ‘Business as usual’ with the Empire in support.

Another example is by the famous Victorian cartoonist Frederick Rose.


Angling in Troubled Waters, 1899. Drawn by Fred. W. Rose, pubished by G.W. Bacon & Co. C1 e.9.

Angling in Troubled Waters shows the troubles caused by the expansionist ideas of the nations of Europe. All have either a fishing rod attached to territorial claims or are in some form of trouble; France fighting amongst itself after the Dreyfus affair, Austria in mourning after the assasination of the Empress Elizabeth in 1898. England, in the guise of John Bull, is the only nation happy with their lot, a common theme in these maps. Carrying a full net of territory Bull has just snagged Egypt on his line. Another famous cartoon map by Rose is ‘Octopus map of Europe’* from 1877, warning of growing Russian influence in Europe.


*The Octopus map of Europe’ by Frederick Rose comes from the Bodleian John Johnson collection, one of the largest and most important collections of printed ephemera in the world, including a number of other cartographic cartoons. This image is from from JJ puzzle pictures folder 1 [28]. information about the John Johnson collection can be found here

Not all cartoon maps are intended for satire though. A book published in 1868 featured maps

Population maps

This population map of the Saxony region of Germany is a recent addition to the map collection. Volksdichte-Schichtenkarte des Königreiches Sachsen nach der Zählung vom 1. Dezember 1900 (Population density layers map of the Kingdom of Saxony after the census of December 1, 1900) shows density of population by colour with two insets for the areas around Dresden and Leipzig from an earlier 1846 census.

Population maps such as this are, in the field of cartography, a relatively recent product, with the first known examples being published in the early 1800s. Early maps would give tables showing population figures, this example from 1822 has one that is Christian only and colours parts of the World depending on the ‘Degrees of Civilization’.

But at the same time different ways to portray population figures were being introduced. This map, from 1849, shows the population of Britain based on figures from the 1841 census by using dots to show sizes of cities, towns and villages as well as shading to show general population density.


British Isles elucidating the distibution of the population…1849, (E) C15 (157)

Our original map of Saxony uses a technique called isopleth to show the density of population. Isopleth uses lines to show areas of equal value, the lines are similar to contours on a physical map and work on the same principle. The main advantage is that you can see at a glance the heavily populated areas by the colour ranges shown on the graph. That Saxony was, in 1900, a mainly rural area can be seen be the amount of green and brown cover shown.
