The original USB stick? 5,500-year-old clay spheres containing Mesopotamian code could be the 'first ever data storage' devices

 

  • CT scans and 3D modelling have now shown what is inside these spheres
  • The spheres are hollow and contain geometric shapes named ‘tokens’
  • The tokens are thought to be the first evidence of numerical literacy
  • Researchers viagra using believe these clay devices served as receipts for various economic transactions

 

A lost code used to keep records 200 years before the invention of the written word has been found inside clay balls in Iran.

The balls were created about 5,500 years ago at a time when early cities were flourishing in Mesopotamia, and could have been used to record economic transactions.

Christopher Woods, a professor at the University of Chicago's Oriental Institute, said the spheres represent the world’s ‘very first data storage system’.
The balls, also called ‘envelopes’, are hollow and contain different geometric shapes or ‘tokens’.

‘These envelopes likely represent the earliest known - at least to our current knowledge - efforts to humans to permanently record data,’ Professor Woods told MailOnline.
‘They may also be the earliest evidence of numerical literacy.’

Researchers used CT scans and 3D modelling to look inside more than 20 examples that were excavated at the site of Choga Mish, in western Iran, in the late 1960s.
They believe these devices served as receipts for various administrative duties such as monitoring the flow of materials, various commodities and labour.

‘The tokens represent numbers of specific metrological (measuring) systems - not words - and the envelopes themselves are receipts for the disbursements of various commodities and goods,’ said Professor Woods.

Museums, understandably, are typically reluctant to open these clay balls as doing so would destroy them and the seal impressions that most of them bear.

Only about 150 complete structures survive today and they range from the size of a golf ball to that of a baseball.

CT scans, however, revealed that some of the balls have tiny channels, 1-2 mm across, criss-crossing them.
Researchers aren’t certain what they were used for, but speculate the balls contained fine threads that connected together on the outside.

The tokens within the balls come in 14 different shapes, including spheres, pyramids, ovoids, lenses and cones, the researchers found.

One pyramid, for instance, might mean a certain unit, such as 20, which was used while counting a certain type of commodity.

All of the clay balls contain, on the outside, one seal running through the middle and usually two seals, running above and below.

Professor Woods believes the seal in the middle represents the ‘buyer’ or recipient.

The polar seals would represent the ‘seller’ and perhaps third parties who would have acted as witnesses.

Clay envelopes such as this have also been found in Mesopotamia, particularly the city of Uruk, by German excavators.
But many questions still remain unanswered. Scientists hope to crack the code of exactly what these clay spheres mean by uncovering how token types vary.

‘We need to study, and hopefully CT scan, the sealed envelopes in other collections,’ said Professor Woods. ‘There are approximately 150 known world-wide.’

Professor Woods plans to put the images and 3D models of the clay envelopes and their tokens online as they become available.
