Carved Stone Balls

Carved Stone Balls are petrospheres, usually round and rarely oval. They have from 3 to 160 protruding knobs on the surface. Their size is fairly uniform at around 2.75 inches or 7 cm across, they date from the late Neolithic to possibly as late as the Iron Age and are mainly found in Scotland, but also elsewhere in Britain and Ireland. They range from having no ornamentation (apart from the knobs) to extensive and highly varied engraved patterns. A wide range of theories have been produced to explain their use or significance, without any one gaining very wide acceptance.

They are not to be confused with the much larger smooth round stone spheres of Costa Rica.

Age and distribution

Carved Stone Balls are up to 5200 years old, coming from the late Neolithic to at least the Bronze Age.

Nearly all have been found in north-east Scotland, the majority in Aberdeenshire, the fertile land lying to the east of the Grampian Mountains. A similar distribution to that of Pictish symbols led to the early suggestion that Carved Stone Balls are Pictish artefacts. The core distribution also reflects that of the Recumbent stone circles. As objects they are very easy to transport and a few have been found on Iona, Skye, Harris, Uist, Lewis, Arran, Hawick, Wigtownshire and fifteen from Orkney. Outside Scotland examples have been found in Ireland at Ballymena, and in England at Durham, Cumbria, Lowick and Bridlington. The larger (90mm diameter) balls are all from Aberdeenshire, bar one from Newburgh in Fife.

Stone carving

Stone carving is an ancient activity where pieces of rough natural stone are shaped by the controlled removal of stone. Owing to the permanence of the material, stone work has survived which was created during our prehistory.

Work carried out by paleolithic societies to create flint tools is more often referred to as knapping. Stone carving that is done to produce lettering is more often referred to as lettering. The process of removing stone from the earth is called mining or quarrying.

The term Stone carving is one of the processes which may be used by an artist when creating a sculpture. The term also refers to the activity of masons in dressing stone blocks for use in architecture, building or civil engineering. It is also a phrase used by archaeologists, historians, and anthropologists to describe the activity involved in making some types of petroglyphs.

History

The oldest known works of representational art are stone carvings. Often marks carved into rock or petroglyphs will survive where painted work will not. Prehistoric Venus figurines such as the Venus of Berekhat Ram may be as old as 800,000 years, and are carved in stones such as tuff and limestone.
