Rock paintings and engravings found in Assam are associated with a variety of prehistoric periods. Some of the earliest known rock art in Assam dates back to the Paleolithic period, while other examples date to the Mesolithic and Neolithic periods. It is also possible that some of the rock art in Assam is from more recent periods, such as the Iron Age or the historic period.
The Paleolithic period is the earliest period of human history, and it is characterized by the use of stone tools. The Mesolithic period is a transitional period between the Paleolithic and Neolithic periods, and it is characterized by the use of both stone tools and polished stone tools. The Neolithic period is the period when humans began to practice agriculture, and it is characterized by the use of polished stone tools and the development of pottery.
The rock art in Assam is a valuable source of information about the prehistoric cultures of the region. The art can provide insights into the beliefs, practices, and technologies of these cultures. It can also help us to understand the relationship between humans and the environment in the past.
However, it is important to note that the rock art in Assam is often difficult to date. This is because the art is often found in remote locations, and it is often exposed to the elements. As a result, the art can be eroded or damaged, and it can be difficult to determine its age.
In addition, the rock art in Assam is often found in association with other archaeological remains, such as stone tools and pottery. However, it is not always clear whether the art is contemporary with these remains. As a result, it is often difficult to determine the exact age of the art.
Despite these challenges, the rock art in Assam is a valuable source of information about the prehistoric cultures of the region. The art can provide insights into the beliefs, practices, and technologies of these cultures. It can also help us to understand the relationship between humans and the environment in the past.
