At the end of 2015 the British Museum put on an exhibition about the Celts, looking at both the original culture in its historical context and the way it was later re-imagined. The overall take home message from the exhibition was that the ancient people we now call Celts probably didn't think of themselves as such, and the modern peoples who we call Celts don't necessarily have that much to do with the ancient Celts.
While I was in a London for a few days in July 2015 I visited the Magna Carta: Law, Liberty and Legacy exhibition at the British Library, which was put on to mark the 800th anniversary of the original issue of the charter. The items displayed in the exhibition were mostly written documents (as you might expect in a library) although there were also some other things, including paintings and examples of seals.
In June we visited the Indigenous Australia: Enduring Civilisation exhibition at the British Museum. The premise of the exhibition was to display the art and showcase the culture of the indigenous peoples of mainland Australia & the Torres Straits Islands from their own perspective. Whilst the later sections of the exhibition inevitably looked at the impact of the arrival of the British the exhibition didn't begin there as if it was the British discovery of the continent that mattered.
Back in April J and I visited the Defining Beauty exhibition at the British Museum which finished in early July. It's the only one of their exhibitions where I've been as ambivalent about it on the way out as I was on the way in - which says rather more about me than the exhibition, I think. The subject of the exhibition was Ancient Greek sculpture and the incredible impact it has had on the modern Western definition of beauty.
Ming: 50 Years that Changed China is the new British Museum exhibition which is open till 5 January 2015. It covers 1400-1450 AD which is close to the beginning of the Ming Dynasty period, and is regarded as one of the Golden Ages of Chinese history. The exhibition opens with a short film which gives a brief overview of the historical events during (and immediately before this period) and puts it into context in terms of how it lines up with British history.
