Looking for a time machine: astrolabes in medieval Jewish society


Josefina Rodríguez Arribas, researcher

Astrolabes are the medieval equivalent of the kind of handheld technology we’re all very accustomed to in the twenty-first century. They were instruments you could use to find your way, tell the time, track the movements of the sun and stars, and were – still are – complex, and incredibly impressive.

As the researcher working on a project with the British Museum and the Warburg Institute to study these fascinating objects, my recent trip to Israel was not the first time I’ve been there in search of medieval astronomy and astrology. However it was the first time I have returned with a database of about 140 Hebrew manuscripts dealing with astrolabes: a treasure trove of texts describing and explaining how to build or use these instruments in their almost two thousand years of history. In other words, texts written mostly in Hebrew and a few in Judaeo-Arabic (Arabic with Hebrew script) between the twelfth and the eighteenth centuries by Jews from around the world (astrolabes remained in use until the nineteenth century in Islamic countries).

These manuscripts are not all physically in Israel – most of them are in libraries and private collections around the world, as are the few surviving Jewish instruments. However, the Jewish National Library in Jerusalem hosts the Institute of Microfilmed Hebrew Manuscripts, in which we can look for and read microfilms of practically all the Hebrew manuscripts in the public and private collections of the world.

Comparing manuscripts

An amazing resource, and very convenient. I can sit in the manuscripts reading room, in the basement of the National Library in Jerusalem, and let my eyes go from a Sephardic script of the thirteenth century to an Askenazi of the fifteenth or a Byzantine of the sixteenth century, all of them explaining how an astrolabe works.

These texts were written and copied by Jews spread over three continents, in countries and cities so close or so distant as Vienna, Istanbul, Egypt, Yemen, Lisbon, Baghdad, Mantua, Benevento, Syracuse, Senegal, and more. Most of them were also copied many times throughout the centuries, some in years as decisive for the history of the world or the history of the Jews as the year 1453 (the fall of Constantinople into Turkish hands) or the year 1492 (edict of expulsion of Jews from Spain), when many codices and manuscripts were destroyed or lost for many reasons.

These handwritten texts are like a time machine encapsulating in their parchment, paper, ink, writing, binding, and list of owners, information about the authors and the readers, the Jewish communities where they were produced and the patrons who paid for them. So the transcription, translation, and study of these texts is going to provide us with decisive information about the degree of scientific knowledge and familiarity with certain scientific instruments of many Jewish communities from the twelfth to the sixteenth centuries, and even later.

In 1966 the Beatles were number one with Paperback Writer, Lyndon Johnson was asked to ‘get out’ of Vietnam, and a gallon of gas cost $0.32. American artist Ed Ruscha travelled 1,400 miles on Route 66 from LA to his hometown of Oklahoma, recording the gas stations dotted along the road. Influenced by graphic design and advertising, he transformed everyday images like this into dramatic works of art.

#EdRuscha #Route66 #USA #graphicdesign #advertising #print #art #LA #1960s #westcoast #printmaking Today marks 30 years since the death of Andy Warhol, hailed as the ‘Pope of pop art’. One of the most recognisable images in the world, Warhol’s Marilyn series remains sensational after five decades. This series of 10 individual screenprints, made in 1967, is on loan from @tate for our #AmericanDream exhibition – opening 9 March. Warhol used a cropped and enlarged publicity still as the source image for this work, taken by photographer Gene Kornman for Monroe’s 1953 film ‘Niagara’. Behind the glamour and fame of the Marilyn series lay tragedy. Recently divorced from playwright Arthur Miller, Marilyn had taken her own life with a drug overdose in August 1962. Warhol’s depiction of the alluring screen goddess became a memorial to a fallen idol.

#WayneThiebaud #popart #art #Americanart #🍭 #🍬 This beaded #wedding blanket was made around the 1950s in South Africa by a Ndebele artist. Under apartheid the Ndebele were forced to live in ethnically defined rural reserves. In response to losing their ancestral lands, Ndebele women began to make distinctive beadwork for significant events.

They also adapted these designs and painted them on their homesteads, to include ever more intricate and colourful patterns. As a form of protest, these artworks had the effect of making Ndebele identity highly visible at a time when the government was attempting to make them effectively invisible through rural segregation.

See this beautiful beaded blanket in our special exhibition #SouthAfricanArt, which traces the history of this nation over 100,000 years. Follow the link in our bio to book your tickets before the exhibition closes on 26 Feb.
#SouthAfrica #history #design #beads #Ndebele #blanket In 19th-century southern Africa, people wore different designs, colours and materials to communicate their power, wealth, religious beliefs and cultural community.

This beautiful beaded necklace is made of brass, glass and fibre, and is known as an ingqosha, a traditional necklace worn by the Xhosa people. Young Xhosa women and men traditionally wear the ingqosha at weddings and ceremonial dances.

During apartheid, necklace designs from the 1800s were used as a form of political and cultural protest. While on the run in 1961, Nelson Mandela was photographed wearing a beaded collar, and after his capture his then wife Winnie reportedly chose one for him to wear during sentencing. By wearing this necklace Mandela made a powerful cultural and political statement about his Xhosa ancestry.

#SouthAfrica #necklace #jewellery #beads #history #art #xhosa We love this great shot of Esther Mahlangu’s stunning BMW Art Car taken by @bitemespice. It’s currently in the Great Court as part of our #SouthAfricanArt exhibition, charting the fascinating history of a nation through its art. The car was painted in 1991 to mark the end of apartheid in South Africa, and the brightly coloured geometric shapes are inspired by the traditional house-painting designs of the Ndebele people.

Mahlangu’s Art Car combines tradition and history with contemporary art and politics; themes  that are explored in our #SouthAfricanArt exhibition. Catch it before it ends on 26 February 2017 – you can book tickets by following the link in our bio.
