Around London – Richmond’s upsized Olympic rings; cart marking; ‘Sam’ Mussabini honored; and, Tudor twins at the NPG…

• The largest official Olympic Rings were unveiled at Richmond Park National Nature Reserve in London’s south-west this week, having been mown into the grass by the Royal Parks’ shire horses. The rings, which lie on Heathrow’s flight path and are 300 metres wide and more than 135 metres tall, will welcome athletes as they fly in to compete in the Games which kick off later this month. It took six shire horses to create the giant rings – which represent five continents – but they’ll be maintained by just two – Jim and Murdoch. Horses have worked in Richmond Park since as far back 1637 when King Charles I had the park enclosed as a royal hunting ground. Eleven Olympic events will be held on Royal Parks during the Games including road race cycling in Richmond Park. For more on Richmond Park, see www.royalparks.org.uk/parks/richmond-park.

• Almost 50 vehicles, ranging from handcarts to horse drawn carriages, steam powered vehicles to a new London bus, took part in the Worshipful Company of Carmen’s traditional ‘Cart Marking’ procession through the City of London yesterday. The ‘trade’ of carmen dates back to the 13th century when City authorities passed a bye-law controlling carters. At the ceremony, the carmen bring a variety of vehicles which are branded by placing a red hot iron on a wooden plate, with the year letter and the car number, in the continuation of an ancient tradition. The Worshipful Company of Carmen is said to be the oldest transportation organisation in the world. For more on the livery company, see www.thecarmen.co.uk.

• The late athletics coach Scipio Africanus “Sam” Mussabini (1867-1927) was honored this week with the unveiling of an English Heritage Blue Plaque at his former home in Herne Hill in London’s south. Mussabini, whose role in helping 100 metre sprinter Harold Abrahams win gold at the 1924 Olympics was depicted in the film Chariots of Fire (he was played by Ian Holm),  lived at the house at 84 Burbage Road from 1911 to about 1916. It backs onto the Herne Hill Stadium where he worked as a cycling and athletics coach from the 1890s, a period during which he trained several medal-winning Olympic athletes. All up, Mussabini’s runners won a total of 11 Olympic medals including five golds, between 1908 and 1928. For more, see www.english-heritage.org.uk.

Around London – Leicester Square reopens; RA and MOL exhibitions mark Diamond Jubilee; ‘Jed’ retires; and, the history of horses at the British Museums…

• Leicester Square officially reopened last night following a £15.3 million transformation which has seen every paving stone replaced, new plants, and 40 new water jets placed around the Grade II listed fountain and statue of William Shakespeare. The 17 month makeover also included new lighting, new seating and a refurb of the underground toilets. The square – which owes its name to Robert Sidney, the 2nd Earl of Leicester, who purchased this land in 1630 and, after building himself a mansion, kept aside part of the land for public use – now welcomes as many as 250,000 tourists a day and is known as one of the world’s premiere sites for the release of new films.

• The Royal Academy of Arts is marking the Queen’s Diamond Jubilee with a new exhibition opening tomorrow which features a selection of paintings by Royal Academicians elected during the early part of the Queen’s reign. The Queen’s Artists will include works by Jean Cooke, Frederick Gore and Ruskin Spear and will be displayed in the Reynolds and Council Rooms. Meanwhile The Saloon will house a collection of sculptures, paintings and drawings prepared by Royal Academicians for British coins and royal seals on loan from the Royal Mint Museum. The collection includes portraits of the Queen by Edward Bawden and Sir Charles Wheeler which have never before been shown in public, and Sir Anthony Caro’s new coin design of the London 2012 Olympic Games. Over in the Tennant Gallery, The King’s Artist’s George III’s Academy, will look at the king’s role in the foundation of the academy in 1768 and his influence in selecting the first artists. Highlights include portraits of King George III (pictured) and Queen Charlotte painted by the academy’s first president, Sir Joshua Reynolds. Admission charge applies.

• A new exhibition focusing on Londoners and their treasured souvenirs commemorating Queen Elizabeth II opens tomorrow at the Museum of London. At Home with the Queen features 12 photographic portraits of Londoners at home with their mementos as well as a selection of royal commemorative objects from the museum’s collection. The latter include trinkets produced for Queen Victoria’s Diamond Jubilee in 1897, official Coronation Day street decorations, Silver Jubilee paper tableware and souvenirs relating to the current Diamond Jubilee. Runs until 28th October. Admission is free. For more (including a series of events running on conjunction with the exhibition), see www.museumoflondon.org.uk.

The Royal Parks’ Shire horse, Jed, retired last week after a decade of service working in Richmond Park. The Queen presented a commemorative retirement rosette to Jed who was born in 1993 and joined the Royal Parks from Bass Brewery in Burton upon Trent almost 10 years ago. Horses have been used in Richmond Park since it was enclosed by King Charles I in 1637. The horses took a break in 1954 but the Shires were reintroduced in 1993 as a way to sustainably manage the parkland. For more on Richmond Park, see www.royalparks.org.uk/parks/richmond-park.

On Now: The horse: from Arabia to Royal Ascot. This major free exhibition at the British Museum is part of the august institution’s Diamond Jubilee celebrations and traces the history of the horse from domestication around 3,500 BC through to present day, with a particular focus on Britain’s equestrian tradition, from the introduction of the Arabian breed in the 18th century to events like Royal Ascot. Highlights include one of the earliest known depictions of horse and rider – a terracotta mould found in Mesopotamia dating from around 2000 to 1800 BC, a cylinder seal of Darius dating from 522 to 486 BC depicting the king hunting lions in a chariot, a 14th century Furusiyya manuscript, an Arabian manual of horsemanship, and the 19th century Abbas Pasha manuscript, the primary source of information about the lineage of purebred Arabian horses acquired by Abbas Pasha (mid-nineteenth century viceroy of Egypt). The exhibition is being held in Room 35. Runs until 30th September. For more, see www.britishmuseum.org.
