Ephemeral maps

These two albums of cuttings show the progress of the First World War through the essentially ephemeral medium of maps for newspapers; being the method the ordinary person could follow the progress of the war visually.  The maps were small scale and general with a strong basic message which had to overcome the disadvantages of poor quality paper and usually small size. Arrows on the map would have covered miles on the ground!

 

 

These maps were not drawn or published to be kept, they were to describe a short period of time which would soon be superseded. In an era without 24 hour rolling news on screens everywhere, these ephemeral maps and illustrations were very important to provide context.

 

 

See this map of the Battle of Messines (7th-14th June 1917) which is in its infancy so much that the newspaper maps have yet to have a title.

Newspaper illustrators did not confine themselves to just to maps as you can see from the diorama sinking of the Lusitania. The diagram gives circumstances of the disaster which would have resonated as there were 123 Americans out of the total 1,195 lost souls.

Another example is the map Location of Mid-West Men which would have particular relevance to our trans Atlantic allies.

The Bodleian has a rich collection of  trench maps and they have been blogged about before here and here but it is interesting to compare the broad brush newspaper image with an actual published map.

 

By being a snapshot in time they provide researchers a very interesting contemporary view of the ebb and flow of the situation on the ground and not a full historical record with all the benefits of hindsight.

 

Depictions of Europe continue after the Armistice was signed until 1st February 1919.  Maps appeared afterwards concerning the changing political situation and the fate of Germany.

The scrapbooks here was bequeathed by Walter Newton Henry Harding, an interesting character and prodigious collector. The story of his vast collections and how they ended up at the Bodleian is the story for another blog but among the 22 tons of material were these two albums full of maps and diagrams cut from Chicago newspapers offering a uniquely transatlantic view.

True north

We are used to having north at the top of our maps. This has been the most common orientation for hundreds of years, largely because of the use of the magnetic compass. Compasses do not, however, point exactly north. The northern magnetic pole wanders around the Canadian Arctic, and anyone requiring precise direction for navigational purposes needs to keep this in mind. It is common for maps to have a diagram showing the difference between magnetic and true north, as in this sea chart from 1870 (which also includes a date for the declination and, elsewhere on the chart, the current rate of change).

The discovery that the earth’s magnetic field fluctuates, and does not line up with its geographical axis, is nothing new. European navigators were aware of this issue from the fifteenth century. Edmond Halley had begun charted the magnetic declination across much of  the world at the end of the seventeenth century, and this map by John Senex from 1725, based on his work, shows the “Line of no variation in the year 1700” curving sinuously across the Atlantic. Lines of equal declination – isogonic lines – are marked around it.

This line where magnetic and true north coincide – properly called the agonic – is also in constant motion and we recently heard the exciting news that it is about to reach the Royal Observatory at Greenwich, so compasses there will point to true north for the first time in 360 years.
