Prehistoric Petrosphere – Carved Stone Spheres and Balls

Prehistoric Petrosphere – Carved Stone Balls are spherical human-made objects made from stone. These ancient artifacts have been created by carving by up to up to 5200 years ago.

These carved stone balls dating from the Late Neolithic to as late as the Iron Age, 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.

They are usually round of reasonably uniform size at around 2.75 inches or 7 cm across. They can have from 3 to 160 protruding knob shapes on the surface. These carved stone balls are nearly all have been found in north-east Scotland, the majority in Aberdeenshire.

As portable objects, they are straightforward to transport and have been found on Iona, Skye, Harris, Uist, Lewis, Arran, Hawick, Wigtownshire, and fifteen from Orkney. A similar distribution to that of Pictish symbols led to the early suggestion that carved stone balls are Pictish artifacts. However, examples have been found in Ireland and England.

Over 425 had been recorded. The British Museum holds a collection of over 30 carved balls from Scotland, Ireland, and northern England. Other collections can be found in the many museums in Scotland.

The lack of balls found in graves may indicate that they were not considered to belong to individuals. Several theories have been produced to explain their use or significance, but none has gained full acceptance.

Many of the balls have not had their discovery site recorded, and most are found as a result of agricultural activity. The lack of context has impacted rigorous interpretation; however, suggestion on their function has included:

  • Some of the balls have grooves or interspaces into which leather could be tied to make a device such as a bolas or a throwing weapon.
  • The rocks are used as movable poise on a primitive weighing machine.
  • ‘Sink stones’ used in conjunction with fishing nets.
  • As oracles,  they were used to interpret as a message from the gods or an answer to a question, depending on how the ball came to rest.
  • They were used to signify the ‘right to speak’ where discussions are controlled by the requirement for the speaker to hold the carved stone ball. The balls fit comfortably in one hand.
  • Use in the working of hides by tying the skins to a frame and using a ball at each corner of the leather, then rubbing down material being worked with stones. The edges of the hides were wrapped around the balls, which allowed the bindings to hold fast without slipping off.

Many of the late Neolithic stone balls have diameters differing by only a millimeter. This discovery has led to the suggestion that they might have been meant to be used together.

Plotting the find sites on a map shows that these petrospheres were often located in the vicinity of Neolithic recumbent stone circles. Models have been created to show how using balls placed in a groove in parallel longitudinal pieces of wood ‘sleepers’ with a carrying board can be used effectively in the transportation of megalith boulders.

Petrosphere

In archaeology, a petrosphere is a term for any spherical human-made object of any size that is composed of stone.

Several classes of petrospheres exist, such as:

  • the stone spheres of Costa Rica
  • painted pebbles from Scotland
  • stone charms from Scotland
  • sandstone balls from such sites as Traprain Law, Scotland
  • the Carved Stone Balls, which are mainly from Scotland
  • carved stone shot for trebuchets
  • Grave Orbs were made throughout Scandinavia.

These prehistoric artifacts may have been altered by significant efforts to perform their specific function.
