    This is the latest in a series of posts about the unfolding of the Norwich shroud, a joint project between the British Museum and Norwich Castle Museum and Art Gallery

As an intern in the textile studio of the British museum, I was lucky enough to have the opportunity to work on the Norwich shroud conservation project. This began in January, and I have been working with the team since the very beginning, participating in all the stages of the conservation treatment.

With decisions about how to conserve the shroud made, we could begin to plan the details of the work.

We first had to make the shroud’s final support board. We used a thick, acid free card that has a honeycomb structure inside. This makes it a very strong but light material, and perfect to use as a large carrying board. We covered it with a brushed cotton fabric to give it a slightly soft padding, and on top of that with a cotton fabric dyed to a neutral beige colour chosen by the team.

Next was the small matter of transferring the shroud onto the board. The handling and moving of a large, fragmentary and fragile textile is not straightforward and needs to be carried out like a military manœuvre.

We needed to get it in the right position on its support board straight away, because once it was on it, the nap of the cotton fabric would grip the shroud fragments and prevent us from moving it around.

Essentially we had to do a double flip to turn the textile over so that it was lying face down, and then back again onto the prepared support board. Each time the textile was sandwiched between rigid support boards to keep it in position.

We put the shroud on its temporary board in exactly the position we wanted it to be on its final support board, measuring in from the edges to ensure it was centred. The prepared final support board was then placed face down, resting directly on the shroud, with the corners of the two boards meeting exactly. The edges of the two support boards were clipped together, and the whole assemblage was turned as quickly as possible.

To secure the shroud to the board without stitching through it, we lay a piece of dyed nylon net. It took over 15 sample dyes to find a colour for the net which least affected the appearance of the shroud, the texts in particular. We viewed the samples under all varieties of lighting conditions and from all angles, and finally got a colour we were all happy with.

The three layers of fabric – that is, the cotton covering the support board, the shroud, and the net, were then secured together with stitches. By stitching through the thousands of small holes in the shroud, we anchor the semi transparent net to the cotton below, and thereby avoid stitching through the actual shroud itself. We use fine silk thread and curved needles that are normally used in surgery.

As we stitch, we have to ensure each thread is aligned in the direction of the weave as best is possible. This delicate work took over four weeks and at times three people were working on different areas simultaneously.

We are still completing this stage of the conservation treatment so it will be ready in time for the next Norwich Shroud Study Day, held at Norwich Castle Museum on May 24. When we’re done, the shroud will be stabilised and can be admired by the public on display or loan. I hope they will take as much pleasure in viewing the object as the team had working on it.

Our #AfricanRockArt project team is cataloguing and uploading around 25,000 digital images of rock art from throughout the continent. Working with digital photographs has allowed the Museum to use new technologies to study, preserve, and enhance the rock art, while leaving it in situ.

As part of the cataloguing process, the project team document each photograph, identifying what is depicted. Sometimes images are faded or unclear. Using photo manipulation software, images can be run through a process that enhances the pigments. By focusing on different sets of colours, we can now see the layers that were previously hidden to the naked eye.

This painted panel, from Kondoa District in #Tanzania, shows the white outline of an elephant’s head at the right, along with some figures in red that it is possible to highlight with digital enhancement.

Tanzania contains some of the densest concentrations of rock art in East Africa, mainly paintings found in the Kondoa area and adjoining Lake Eyasi basin. The oldest of these paintings are attributed to hunter-gatherers and may be 10,000 years old.

The project team are now in the third year of cataloguing, and have uploaded around 19,000 digital photographs of rock art from all over #Africa to the Museum’s collection online database.

This photograph shows an engraving of a large, almost life-sized elephant, found on the Messak Plateau in #Libya. This region is home to tens of thousands of depictions, and is best known for larger-than-life-size engravings of animals such as elephants, rhino and a now extinct species of buffalo. This work of rock art most likely comes from the Early Hunter Period and could be up to 12,000 years old.

Watch the incredible discovery of this colossal statue, submerged under the sea of thousands of years. This colossal 5.4-metre statue of Hapy was discovered underwater in what was the thriving and cosmopolitan seaport of Thonis-Heracleion. It once stood in front of a temple and would have been an impressive sight for traders and visitors arriving from the Mediterranean.

Come face to face with the ancient Egyptian god Hapy for yourself in our‪ #SunkenCities exhibition, until 27 November 2016.

The discovery of this stela, which once stood at the entrance of the main entry port into ancient Egypt, was an extraordinary moment. Its inscription detailing taxes helped solve a 2,000-year-old mystery!

This magnificent monument was crucial to revealing that Thonis (in Egyptian) and Heracleion (in Greek) were in fact the same city. The decree was issued by the pharaoh Nectanebo I, regarding the taxation of goods passing through the cities of Thonis and Naukratis, and it originally stood in the Temple of Amun-Gereb. The inscription states that this slab stood at the mouth of the ‘Sea of the Greeks’ (the Mediterranean) in Thonis.

A bilingual decree found in 1881 refers in its Greek inscription to ‘the Temple of Heracleion’ and in hieroglyphs to ‘the Temple of Amun-Gereb’. Together these objects revealed that Thonis and Heracleion were the same place.

For centuries nobody suspected that the #SunkenCities of Thonis-Heracleion and Canopus lay beneath the sea. Recorded in ancient writings and Greek mythology, the ancient Egyptian cities were believed to be lost.

Over the last 20 years, world-renowned archaeologist Franck Goddio and his team have excavated spectacular underwater discoveries using the latest technologies. The amazing rediscovery of these lost cities is transforming our understanding of the deep connections between the great ancient civilisations of Egypt and Greece.

#archaeology #diving #ancientEgypt This week we’re highlighting some of the incredible clocks and watches on display in the Museum. Mechanical clocks first appeared in Europe at some time between 1200 and 1300. Their introduction coincided with a growing need to regulate the times of Christian prayer in the monasteries. Telling the time with a sundial was especially difficult in western Europe with its unreliable weather. From the end of the 13th century, clocks were being installed in cathedrals, abbeys and churches all around Europe.

The design of turret clocks (public clocks) changed little over the following three centuries and this particular example, made around 1600, has similar characteristics to clocks made for churches in the medieval period. The maker of this clock was Leonard Tenant, one of the most prolific makers of church clocks in the first half of the 17th century. The clock was installed in Cassiobury Park, a country house near Watford.
