The domestication of the horse is considered to have been first achieved in the Eurasian steppes around 3500 BC and brought great benefit to ancient cultures in terms of transport and labour, and warfare. The development of the mounted archer was one of the most dramatic changes in ancient warfare, leading to some of the most successful warriors of ancient times who largely owed this to their proficiency with the horse. Accordingly, the horse became an extremely important symbol of power and their image was highly regarded. As well as depictions of horses, practical artefacts relating to riding were also of great importance and as such were often used as funerary offerings. It is also not uncommon for remains of real horses to be found in tombs from various cultures, including the Bronze Age tomb at Lefkandi, the Yin Dynasty of China, and the Iron Age Celts.
