One of the things I love about working with collections is how much I end up learning not just about the collection itself but also about the world. And all without needing to study! The saying: \u201cYou learn something new everyday\u201d, really does hold true for collections work and I thought I\u2019d share some of my fun discoveries with you.<\/h2>\n

Since mid-March or so, many of us have been working from home during the COVID lockdown, and collections staff are no different. Despite much of our work being hands-on when we are in the Museum and behind-the-scenes, there is also a lot we can do remotely. One of these is to update and maintain records on our Collections Management Database, or CMS, where we store information about our collection.<\/p>\n

I\u2019ve been working through a backlog of object images and uploading them to the database, transcribing labels and tidying up the object records as I go. Thanks to the magic of technology and the internet, this information is then available to view online, at https:\/\/collections.maa.cam.co.uk<\/a><\/p>\n

You may have already seen my earlier blog about marsupials and how they are relevant to the collection<\/a>. Are you ready for part two?<\/p>\n

<\/h3>\n

What is Nacre?<\/h3>\n
\"\"
Forehead ornament made from polished Nautilus nacre (Z 9765)<\/figcaption><\/figure>\n

 <\/p>\n

This was listed in the Accession Register as a \u201cstar-shaped forehead ornament, nacre.\u201d Alfred Cort Haddon collected it in 1898 from an island called Mer in the Torres Strait. Alongside the Accession Register, we keep catalogue cards which detail information about objects in the collection. The catalogue card for this object says it was worn on a headband for dances.<\/p>\n

Assuming nacre is a material and not a place or people, it\u2019s fairly clear that it has something to do with shells. But what exactly?<\/p>\n

Nacre, also known as mother of pearl, is an iridescent material made by molluscs for protection. It creates a smooth lining inside some shells and can build up around foreign bodies, forming pearls. Although its original purpose is protection, it has long been used by humans as a decorative substance, and can be seen in many of Museum of Archaeology and Anthropology<\/a>‘s (MAA\u2019s) objects. Here are some examples:<\/p>\n

\"\"
Shield made of woven rattan inlaid with mother-of-pearl (E 1904.135 B)<\/figcaption><\/figure>\n

 <\/p>\n

This shield was bought for the museum using funds donated by Professor Anthony Ashley Bevan. It was made in the Solomon Islands and is inlaid with many small section of nacre.<\/p>\n

 <\/p>\n

\"\"
Detail from a wood and mother of pearl snakes and ladders board (1951.995)<\/figcaption><\/figure>\n

 <\/p>\n

This game board was brought back from India in 1857 by Sir Richard Charles Lawrence and donated to the Museum. It was acquired in circumstances that remain unclear in the aftermath of the suppression of the Indian Uprising. We do not know who it previously belonged to. Each square contains a name written in Persian characters and inlaid with nacre.<\/p>\n

If you\u2019re feeling up to a bit of chemistry and fancy learning why shells are difficult to smash and how the windowpane oyster got its name, check out this podcast<\/a> on nacre from Chemistry World.\u00a0<\/em><\/p>\n

<\/h3>\n

What is a false cowrie?<\/h3>\n
\"\"
Forehead ornament made of pieces of false cowrie shells (Z 9266)<\/figcaption><\/figure>\n

 <\/p>\n

This frontlet is listed in the Accession Register as \u201cFrontlet of Ovulum shells,\u201d and the database description used the term \u201ccowrie shells\u201d. But there is no such thing as an \u201cOvulum shell\u201d and these don\u2019t look like the cowrie shells we might be familiar with. So what is going on?<\/p>\n

It turns out that there is a family of predatory or parasitic sea snails called Ovulidae. They are also known as the cowry allies or false cowries. Given the strange term \u201cOvulum,\u201d we believe that this frontlet is made from pieces of Ovula ovum, or the common egg cowrie.<\/p>\n

Cowries and cowry allies are part of the same superfamily, Cypraeoidea, but they are distinct groups. The cowries used as currency in some parts of Africa, Asia and the Pacific Islands, are the much smaller Monetaria moneta (\u2018Money Cowrie\u2019) and M.annulus (\u2018Gold-Ringed Cowrie\u2019).<\/p>\n

Cowries have also been used as protective charms and decoratively in many cultures. Here are some examples within MAA\u2019s collection:<\/p>\n

\"\"
Cowries and glass beads (1927.862)<\/figcaption><\/figure>\n

These cowries are part of a Buddhist rosary, which was collected in China by Sir William Ridgeway. They were donated to the museum in 1927.<\/p>\n

\"\"<\/p>\n

This is a royal drum from the Kingdom of Buganda, Uganda, covered with cowrie shells and glass beads. John Roscoe, a missionary who lived and worked in Uganda during the turn of the 19th-20th centuries, donated it to the museum.<\/p>\n

Want to discover more? Here\u2019s a little snippet from the Smithsonian Museum Natural History collection about why some cowries might be too pretty for their own good<\/a>.<\/em><\/p>\n

<\/h3>\n

That\u2019s all for now<\/h3>\n

Well done, you\u2019ve reached the end of this whirlwind tour! As you can imagine, I\u2019ve only shared a tiny fraction of the shells in our collections, so why not take a look yourself at what else we have?<\/p>\n
