Currently on is the exhibition: Scythians: warriors of ancient Siberia, until 14th January 2018.
Trading on the Game of Thrones Dothraki imagery, this is an amazing display covering the east and west extents of the scythians' domain. Permafrost preserved burials have revealed a wealth of material (literally).
gold plaques, buckles and horse tack, false beards, colourful leather bag containing cheese (2300 years old!), headgear for people and for horses, swords, axes, bows, armour...
The metal work is accompanied by magnified X-rays and proposed manufacture techniques. There are colourful reconstruction illustrations. Exhibits also cover the world with which they traded, including china, Achaemenid Persia and Bactria.
I spent a good hour going round. Thoroughly recommended if you get the chance. I may even have been inspired enough to paint up an army!
