An image of a man in an akimbo pose, with his arms raised up, is seen on a small plaque found in Pskov (Plate LXXIII, 1 in Sedov 1982). The man's legs, slightly bent, as if dancing, are reminiscent of the silver figurines of the Martynovsky treasure, which includes four anthropomorphic figurines of 'dancing men' in a style sometimes considered as influenced by Huns, Bulgars or Avars' https://en.wikipedia.org/wiki/Martynivka_Treasure
