Dotting the ’i’s…


Silke Ackermann, former British Museum curator

It’s been a while since the last post about this project, as much has happened since Josefina wrote about her research trip to Israel. Not least is the fact that I have left the British Museum for a professorship at the University of Applied Sciences at Schwerin (Germany). I will stay involved in the project in various ways, but the British Museum will not.

However, I wanted to write a final post to report on our study of two instruments. One was the famous medieval astrolabe with Hebrew markings in the British Museum, that has already played a role in the BBC Radio 4 series A History of the World in 100 Objects as object no. 62. The other is a later astrolabe in a private collection that had been deposited at the Museum by an owner keen to learn more about his object. This is a service that curatorial departments of the Museum regularly perform.

We were keen to get a better feel for the instruments; to examine the lettering, and explore the language used to see what it might tell us about the cultural circumstances in which they were made, and to take a close look at a much younger astrolabe, constructed at a time when the instrument had largely gone out of use.

An examination of the markings on both instruments made it quite clear that the language used is Judeo-Arabic in both cases, that is Arabic written in Hebrew letters. This is a phenomenon that can often be observed where Jewish people are living in an Arabic-speaking-community. They may well be speaking Arabic themselves, but will often use Hebrew letters for writing as this is the script they will have learnt. To indicate letters otherwise not used in Hebrew, certain letters will have special signs, normally dots.

Scientific analysis has shown the later piece to be made of rolled metal, a technique that was virtually unknown before the nineteenth century. This means it was made when the use of astrolabes had largely been superseded by other instruments.

When examining this instrument in detail we were struck by the fact that some of the numerals used to indicate values for – amongst other things – latitudes appeared to be full of mistakes. This, together with the late date of the instrument, might on first glance raise suspicion about its authenticity. However, the explanation appears to be a completely different one. One should note that these numerals are not written in ciphers, but in the so-called ‘alphanumerical system’, that is a system used in all Semitic languages (and also in Greek) where each letter of the alphabet also stands for a numerical value. Thus aleph stands for 1, bet for 2 etc. The numbers we had been looking at should have read ‘15’ – jod he in Hebrew. However, this letter combination looks identical to an abbreviation for the name of God – and would thus have been avoided by observant Jews. Other features of this particular instrument seem to indicate that it was carefully copied from an earlier source, probably by a scholar who was reading the medieval texts trying to understand or to teach how such an instrument might have worked.

I know I’m biased, but isn’t it truly amazing what we can learn just by looking at instruments?! Working in a museum one soon begins to realize that it is often objects that give us the cultural and social contexts that we cannot glean from written sources alone – and it is the combination of instruments and texts as the historical basis for our research that makes this project so exciting for me.

In the @ImperialWarMuseums exhibition ‘Fashion on the Ration: 1940s street style’ we can see how men and women found new ways to dress while clothing was rationed. Displays of original clothes from the era, from military uniforms to utility underwear, reveal what life was really like on the home front in wartime Britain.

Despite the limitations imposed by rationing, clothing retailers sought to retain and even expand their customer base during the Second World War. Britain's high street adapted in response to wartime conditions, and this was reflected in their retail ranges. The government intervened in the mass manufacture of high street fashions with the arrival of the Utility clothing scheme in 1942. Shoppers carefully spent their precious clothing coupons and money on new clothes to make sure their purchases would be suitable across spring, summer and autumn and winter. Despite the restrictions, the war and civilian austerity did not put an end to creative design, commercial opportunism or fashionable trends on the British home front.

#FashionontheRation exhibition runs @imperialwarmuseums until 31 August.

Clothes were rationed in Britain from 1 June 1941. This limited the amount of new garments people could buy until 1949, four years after the war's end. The British government needed to reduce production and consumption of civilian clothes to safeguard raw materials and release workers and factory space for war production. As with food rationing, which had been in place since 1940, one of the reasons for introducing civilian clothes rationing was to ensure fairness. Rationing sought to ensure a more equal distribution of clothing and improve the availability of garments in the shops.

As this poster shows, the rationing scheme worked by allocating each type of clothing item a 'points' value which varied according to how much material and labour went into its manufacture. Eleven coupons were needed for a dress, two needed for a pair of stockings, and eight coupons required for a man's shirt or a pair of trousers. Women's shoes meant relinquishing five coupons, and men's footwear cost seven coupons. When buying new clothes, the shopper had to hand over coupons with a 'points' value as well as money. Every adult was initially given an allocation of 66 points to last one year, but this allocation shrank as the war progressed. © IWM (Art.IWM PST 8293) This week on @instagram we’ve joined up with other London museums to highlight our shared stories. Our partner is @imperialwarmuseums, whose incredible collection brings people’s experiences of modern war and conflict to life. Follow #MuseumInstaSwap to discover some of the intriguing historical connections we have found, as well as insights into everyday life during wartime. As part of our #MuseumInstaSwap with @ImperialWarMuseums, we’ve been given special access to the Churchill War Rooms – located deep below the streets of Westminster.
This is Prime Minister Winston Churchill’s bedroom, which includes his private desk, briefcase and papers, his bed and chamber pot and even an original cigar! The bedroom is located close to the Map Room, keeping Churchill as close as possible to the epicentre of Cabinet War Rooms.
Following the surrender of the Japanese Forces the doors to the War Rooms were locked on 16 August 1945 and the complex was left undisturbed until Parliament ensured its preservation as a historic site in 1948. Knowledge of the site and access to it remained highly restricted until the late 1970s when @ImperialWarMuseums began the task of preserving the site and its contents, making them accessible to as wide an audience as possible and opening them to the public in 1984.
Discover more stories from London’s museums with #MuseumInstaSwap We’re exploring the Churchill War Rooms – the secret underground headquarters of the British government during the Second World War – in partnership with @ImperialWarMuseums for #MuseumInstaSwap.
The fear that London would be the target of aerial bombardment had troubled the government since the First World War and in 1938 the basement of a Whitehall building was chosen as the site for the Cabinet War Rooms. From 1940 to 1945 hundreds of men and women would spend thousands of vital hours here and it soon became the inner sanctum of British government.
Here you can see the wall of the Map Room, detailing the positions of British convoys across the world, which has not changed since 1945! Today in #MuseumInstaSwap we’re beneath the streets of Westminster to discover the hidden secrets of the #WW2 Cabinet War Rooms, which is part of @ImperialWarMuseums.
This is the underground bunker that protected the heart of Britain’s government during the Second World War as Prime Minister Winston Churchill and his inner circle plotted the route to Allied victory. It’s an amazing experience to step back in time and walk in the footsteps of Churchill, glimpsing what life would have been like during the tense days and nights of the Second World War. This archive photo shows Churchill at his desk in the Map Room at the Cabinet War Rooms. Beside him, Captain Pym of the Royal Naval Volunteer Reserve (RNVR) takes a telephone call. To this day, the Map Room has remained exactly as it was left on the day the lights were switched off in 1945.
