There are various kinds of scripts, letters, carved on the granite slabs of the tombs of Ibbankatuwa civilization. It is found that the scripts engraved on pots containing ash and skeletons, had been carved with letters and several signs for identification. These are the evidence to prove that there was letters and signs for communications in this civilization.
In addition to the items considered under the civilizations such as tools, weapons, remains of skeletons of humans and animals, and other fossils, pieces of metal, clay pots, seeds and other different types of articles, the paintings, symbols and geometrical lines give clues of the life patterns of the civilizations of pre historical period.
The forefathers of the Balangoda pre historic human, lived 120 000 years ago, have used the primitive pictures, different kinds of signs and symbols in geometrical lines on the walls of caves and rock shelters by engraving, scratching which have been used as communication.
There are several caves identified as evidence to these communications methods such as Thanthirimaley, Arangoda, Billewa, Adiyagala caves of Anuradhapura Dorawaka cave of Kegalla, Rajagal kanda and Gonagolla caves of Ampara and Padiwettumalei in Sangamankanda of Ampara.
It can be believed that the area around Thanthirimale closer to Malwathu Oya had been a developed civilized from the period of pre historic. Earliest evidence of the pre history of Thanthiimaley can be found at the cave containing the engravings, paintings and other geometrical lines, red and black head unclear leopard or tiger image, humans carrying bows and arrows, sign of sun, animals, birds, and several other images of humans.
Proofs found from Dorawaka Lena of Keggalla can be considered as proofs of the transferring period from Mesolithic to Neolithic. There are signs, letters, paintings and other geometrical lines such as images of sun and moon, arrows, images of fish, elephant, and several other paintings found in this cave.
The image of elephant engraved at the left side of the cave is very much famous and owing to this, this cave is named as “Ethabedi Lena”.
This site is in kotmale in Ampara District. There are some pre historic paintings in one of the caves in Gonagolla, a female dancer and a man painted with colours in red yellow, green and white are visible.
Pre histiric paintings and engravings found from Padiwettumalei in Sangamankanda of Ampara.
There are caves with drip ledges with pre historic paintings and engravings and inscriptions of Brahmi letters. Quoted below are a few of them.

It can be believed that people lived in this period have been engaged with this type of painting during their leisure time to express their sentiments, expressions and feelings.
There are three types of these cave paintings. That is single coloured, multi coloured, and engraved paintings.
The paintings done in single colour have been done with the help of stick or fingers. The multi coloured paintings have been outlined by single lines and painted in different other colours thereafter. Kaduru Pokuna is an ex. for multi coloured paintings. Engraved paintings are engraved on the walls of the caves or rock shelters itself.
It can be understood that these pre historic humans were good in selecting colours in their paintings as it reflects the way they have painted the skulls found from Rawana Ella caves and Pahiyangala caves.
There are items found at the Pahiyangala cave such as colours on the grinding stones, rocks of different colours, leaves and barks of trees used for extracting colours and animal blood are the evidence to prove that they have been used these items for paintings.
Although the paintings, engravings and other geometrical signs found in pre historic periods from other countries contain hunting and the fights against other tribes, the paintings found in Sri Lanka reflect the co-habitation of human with the animals and the environment and this is a significant feature of them comparing to other countries.
