The discovery of a Pazyryk frozen prince's tomb in Berel'(Altaï, Kazakhstan) led to the unearthing of a funerary chamber enclosing two human bodies and thirteen horse bodies. The horses were buried harnessed beside the humans and some of them were wearing masks and two fake ibex horns in gold-painted wood. Meticulous excavation and the study of the resulted in a description of the animals and revealed the importance of their position in the tomb — as well as the selection criteria that led to their sacrifice.
