• The British Library has paid £9 million for a 7th century text, the St Cuthbert Gospel, which is also the oldest intact European book. The acquisition follows the library’s most successful fund-raising effort ever – it included a £4.5 million grant from the National Heritage Memorial Fund. The book – a Gospel of John bound in beautifully tooled red leather – was produced in north-east England in the late 7th century and was placed in the saint’s coffin after his death on the Isle of Lindisfarne in 698. It was retrieved when the coffin was opened at Durham Cathedral in 1104. The Gospel is on display in the Sir John Ritblat Treasures Gallery at the library in St Pancras and following a conservation review, it is anticipated it will soon be displayed with the pages open for the first time. There will be a public event celebrating the acquisition on 15th May. For more, see www.bl.uk/whatson/events/may12/index.html.

• On Now: Turner Inspired – In the Light of Claude. The first major presentation of 17th century artist Claude Gellée’s influence on the English romantic artist J M W Turner, the exhibition focuses on Claude-inspired themes which run through Turner’s work including “the evocation of light and air in landscape, the effect of light upon water and his often radical reworking of contemporary scenes”. The display includes works from large scale oils on canvas through to leaves from Turner’s pocket sketchbooks. Interestingly, the exhibition also explores the story behind the so-called Turner Bequest – that on his death, Turner linked himself to Claude forever by leaving the National Gallery two pictures – Dido building Carthage (1815) and Sun rising through Vapour: Fishermen cleaning and selling Fish (before 1807) –  on condition that they were hung between two pictures by Claude, Seaport with the Embarkation of the Queen of Sheba (1648) and Landscape with the Marriage of Isaac and Rebecca (1648). Runs until 5th June. Admission charge applies. For more, see www.nationalgallery.org.uk.

Earlier this month it was former US President Ronald Reagan’s turn to be honored with statue in Grosvenor Square. Last week it was the turn of former Soviet Cosmonaut Yuri Gagarin – the first man in space – to be so honored with a new statue located outside the British Council’s offices in the Mall (opposite another explorer, Captain James Cook). The statue, a gift of the Russian Space Agency Roscosmos, was unveiled to mark the 50th anniversary of Gagarin’s celebratory visit to London on 14th July, 1961, just three months after he completed his orbit of the earth on 12th April that year. The 3.5 metre high zinc alloy figure stands close to Admiralty Arch which was where Gagarin met then Prime Minister Harold MacMillan after he was invited to the UK by the National Union of Foundrymen. Among those present for the unveiling of the statue – which is a replica of one in the town of Lubertsy where Gagarin worked as a foundryman as a teenager – was Gagarin’s daughter Elena Gagarina, now director of the Kremlin Museums, and Vladimir Popovkin, head of the Russian Federal Space Agency. The British Council is running an exhibition, Gagarin in Britain, which looks at the life of Gagarin and the early Soviet space programme, until 14th September – among the objects on display is the first space suit and an ejector seat similar to that Gargarin used when he ejected out of Vostok 1. Entry is by registration only and space is limited – email gargarin@britishcouncil.org is you’d like to register for a place.

A new iPhone app which directs people to key sites in what was Roman London (Londinium) will go live on Monday. Developed by the Museum of London and the History Channel, Streetmuseum Londonium will bring to life some of the city’s most significant Roman sites, such as the amphitheatre at Guildhall, using “augmented reality video” which will overlay scenes of Roman London over the modern city while soundscapes will allow users to listen to a ritual at the Temple of Mithras or traders at the forum. In addition, users will be able to ‘digitally excavate’ Roman artifacts including leather bikini briefs and an ancient manicure set. Navigation to these “immersive experiences” will be via a specially created new map of Roman London which will be superimposed on a modern map of the capital, allowing users to see how the city has changed. The launch follows the earlier creation of the Streetmuseum app which guides people to more than 200 sites across the city. More than 200,000 people from across the world have so far downloaded this. Streetmuseum Londinium will be available free to download from 25th July. See www.museumoflondon.org.uk/apps for more.

• The British Library hopes to raise £2.75 million to acquire the world’s earliest surviving intact European book, the 7th century St Cuthbert Gospel. A copy of the Gospel of St John, the book was buried with St Cuthbert on the isle of Lindisfarne in 698 and later found in the saint’s coffin in Durham Cathedral in 1104. The National Heritage Fund Memorial has already awarded £4.5 million to obtain the St Cuthbert Gospel and the Art Fund and The Garfield Weston Foundation have donated £250,000 each. The book has been on long-term loan to the library since 1979 and is regularly on view in the Sir John Ritblat Treasures Gallery. The library was approached last year and given first option to acquire the text after the Society of Jesus (British Province) decided to sell it. A price of £9 million has been agreed, of which £2.75 million remains outstanding. For more, see www.bl.uk.
