Ruhuna - Stone ellipsoid - Grooved
A stone ellipsoid (axis ratio equals half) with many spiral groves carved on it from one rounded end to the other. Found in Akurugoda in area of Tissamaharama. Age and usage unknown.
The grooved stone ellipsoid may be a seal that is rolled to get impression. Larger stones like this are used to grind spices. Maybe this stone also had a similar application.
Such a stone roller is not listed in the 1999 catalog by Osmund Bopearachchi and Rajah Wickramasinhe titled Ruhuna. An Ancient Civilization Re-visited . It was obtained from the same collector who provided most of the items for that book.
If anyone has information on the age and use of items like it please let me know details about it.
The ellipsoid was scanned at 300 dpi and displayed at 300 dpi. It was obtained in 2001 December from Mr A. Ratnayaka a collector in Katharagama, Lanka.
