        Stone Balls: (Petrospheres).

There are two kinds of Petrospheres - Those fashioned by humans, and those formed by nature.

There have been several suggestions to attempt to explain why people were driven to produce stone balls on such a large scale (as in the case of Scotland and Costa Rica), ranging from symbols of wealth or status to geometric aids or because of their serene, harmonic beauty, but there are more than enough examples to show that stone itself was given a form of reverence in prehistory, and was likely seen as being endowed with 'special' qualities (as shown by the specific selection and transport of stone at Megaliths). Certainly other cultures appear to have become 'besotted' with stone carving such as the Easter Islanders, Egyptians, Mayans, and perhaps that is all we see with carved petrospheres.

   Featured Petrospheres:

The Scottish Stone Balls:

The majority of the balls were discovered in Aberdeenshire, an area also associated with a high concentration of recumbent stone circles. Most of the stone balls conform to a standard size and over half have six embossed geometric knobs carved onto them, although some have as many as 160 dimples engraved on them.

Over 400 of these small geometric carved stones have been discovered in Scotland. Curiously, they appear to have been made with an understanding of the 'platonic solids', as the majority of them have been designed to conform with one of the five geometric solids.

The Giant Stone Balls of Costa Rica:

With over 300 of the carved stone balls having so far been discovered, ranging in size from a few centimetres to over 2 metres (6.6 ft) in diameter, and weighing up to 16 short tons (15 t), Costa Rica offers both the largest and  the worlds richest supplies of carved stone spheres, believed to have been carved between 200 BC and 1500 AD, their origin and purpose is still unknown.


The Navel of the Navel - Easter Island.

There is a carved stone sphere on Easter Isle at the northern coastal area of the island, just north of the statue quarry at the volcanic crater of Rano Raraku. The site, "Te pito kura" was most likely a ritual centre for the earliest islanders to pray and divine.

The islanders have a legend that the statues were moved by the use of mana, or mind power, and according to one legend, use was made of a finely crafted stone sphere, 75 cm (2.5 ft) in diameter, called te pito kura (�the golden navel� or �the navel of light�), to focus the mana.

Olmec Stone HeadsThe Giant Olmec Stone Heads:

Several of these large stone heads have been found associated with ceremonial Olmec sites in the Mexican Gulf. The basalt stone for these heads was transported from up to 50 miles in some cases, and the Negroid features have led some to suggest a pre-Columbian contact with Africa. There are also petrospheres reported but it is unknown if they are natural or carved.


   Natural Petrospheres:

Nature has provided us with some incredible examples of petrospheres (concretions), of which some of the best (the most spherical) are shown in the following images.

Bosnia: There have been several reporting's of Petrospheres from Bosnia, a country which has been in the limelight recently following claims of the discovery an ancient pyramid complex near Visoko in Bosnia Hertzogovnia. Although this has fuelled the idea that the Bosnian petrospheres are carved, all such claims have been refuted by geologists.

The largest site in Bosnia known for stone balls is the County Zavidovici, approx. 100 km north of Sarajevo. It is the first place in Europe which has established an �Archaeological Park of Stone Balls". This site contains approx. 40 stone balls of enormous size, all of which are recognised as natural 'concretions'.

The Chinese 'Volcano Eggs'

'A large number of "Volcano eggs" were recently discovered along with a copper sword at a construction site in Bandeng Hill and Zhanlong Hill, Gongxi Town of Hunan Province. The discoveries were made by highway construction workers while they were digging the foundation for a road. geologists believe that the stone eggs are rare, large concretions of the carbonate rock'. (1)

'The construction workers said that Bandeng Hill is quite simply a stone-egg mountain. They found multiple nests of unique stone eggs throughout the course of digging the road's foundation. The eggs are oval in shape, with a wide range of sizes; the smallest one being no bigger than a water melon, while the largest is reported as being the size of a big table. Upon closer examination they look like eggs from the outside, but are very shiny and black on the inside'.
