A common practice in the Bronze Age was to deliberate break/deform bronze (often in the manufacturing process) and place it in water, or bury it. Like some of the object above on display at Andover Museum and Museum of the Iron Age.
Another good example of this practice is at Flag Fen near Peterborough. Starting off as a Neolithic Causeway, and developed in the Bronze Age, the site was comprised of around 60,000 wooden timbers (some wood used to make the causeway, like oak, were not natural to the local area), and for around 1 kilometer. In middle was n island and due to associated finds, such as high status bronze items, animal remains (mainly horse), polished stones, has been interpreted as a site of special religious/spiritual significance. Some of these bronze items, such as daggers were deliberately broke in two and placed on top of each other. This was potentially to make them not usable by the world of the living, but broken to be used in the land of the dead.
Some archaeologists suggest that wood and water played a very important part in the lives of the prehistoric people and that they formed liminal barriers between the world of the living and of the land of the dead.
