Tamil Sangam Age is 300 years older than believed, Scripts of Indus valley Civilization and Tamil Brahmi are connected; an excavation in Tamil Nadu leads to a Major Discovery

In a major turning point in the cultural historiography of the ancient Sangam Age, the Tamil Nadu Archaeology Department (TNAD) has stated that the cultural deposits unearthed during excavations at Keezhadi in Sivaganga district could be safely dated to a period between 6th century BCE and 1st century CE.

As per historians, the artifacts unearthed in the region have a possible link between the scripts of the Indus Valley Civilization and Tamil Brahmi (language).

Carbon dating suggests that the cultural deposits may be 300 years older than believed.

This is the first time the date has been officially announced by the Tamilnadu Archaeological Department.

The new findings in the report, released on Thursday by Minister for Tamil Culture and Archaeology K. Pandiarajan here, place Keezhadi artefacts about 300 years earlier than previously believed — 3rd century BCE As reported by The Hindu.

One of the six samples collected at the depth of 353 cm and sent for carbon dating test in the U.S. “goes back to 580 BCE,” Commissioner of Archaeology T. Udayachandran said.


The report titled, ‘Keezhadi-An Urban Settlement of Sangam Age on the Banks of River Vaigai’, was published by the TNAD.

The results from the fourth excavations suggest that the “second urbanisation [the first being Indus] of Vaigai plains happened in Tamil Nadu around 6th century BCE as it happened in Gangetic plains.”

The report also spells the site as Keeladi as against the erstwhile widely used Keezhadi.

After analysing the AMS dates, archaeologist Professor K. Rajan felt that Keezhadi presented strong evidence for some of the hypotheses. Skeletal fragments were sent to Deccan College Post Graduate and Research Institute in Pune, and it identified them of species such as cow/ox (Bos indicus), buffalo (Bubalus bubalis), sheep (Ovis aries), goat (Capra hircus), nilgai (Boselaphus tragocamelus), blackbuck (Antilope cervicapra), wild boar (Sus scrofa) and peacock (Pavo cristatus).

This finding suggests that the society in Keezhadi had used animals predominantly for agricultural purposes,” Mr. Udhayachandran said as reported by The Hindu.

Found Tamil-Brahmi potsherds:

Fifty-six Tamil-Brahmi inscribed potsherds were recovered from the site of excavation conducted by the TNAD alone, the report stated.


Pottery specimens from Keezhadi sent to the Earth Science Department of Pisa University, Italy, through Vellore Institute of Technology for mineral analysis, confirmed that water containers and cooking vessels were shaped out of locally available raw materials.

Recovery of 10 spindle whorls, 20 sharply pinpointed bone tip tools used for design creations, hanging stones of the yarn, terracotta spheres, copper needle and earthen vessels to hold liquid clearly attest to the various stages of weaving industry from spinning, yarning, looming and weaving and later for dyeing,” the report added.

These results clearly ascertained that they attained literacy or learned the art of writing as early as 6th century BCE,” the 61-page report stated.

Six carbon samples collected from the fourth season (2018) of excavations at Keezhadi were sent to Beta Analytic Lab, Miami, Florida, U.S., for Accelerator Mass Spectrometry (AMS) dating.

Indus Valley Civilization and Tamil Brahmi (language) are connected:

As the excavation was carried out in Keezhadi village of Sivagangai district in Tamil Nadu where archaeologists have made some major discoveries which will add to the Indian history pages.

As per historians, the artefacts unearthed in the region have a possible link between the scripts of the Indus Valley Civilization and Tamil Brahmi (language).

The Indus Valley Civilization in India happened between 5,000 BCE and 1,500 BCE in north-western part of the country. The civilization crumpled in 1500 BCE and it is believed that people might have moved to the south of India. The script used by the Indus Valley people is known as the Indus script, and historians speculate that the language could be Dravidian. Now, the recent discovery at Keezhadi shows that there is a possibility that these two cultures are connected.

The discovered samples displaying graffiti belong to 580 BCE, which is believed to be the link between the Indus script and the Tamil Brahmi.

According to the Tamil Nadu Archaeological Department (TNAD) report known as Keezhadi-An Urban Settlement of Sangam Age on the Banks of River Vaigai, the cultural findings belong sometime between the 6th century BCE and the 1st century CE. The artefacts could belongs as far back as 580 BCE, as per report.

The report, explaining the importance of the findings mentions that “Among the available scripts of India, the Indus scripts are considered to be the earliest one and were 4500 years old. One kind of script that survived between the disappearance of Indus script and the emergence of Brahmi script is called as graffiti marks by the scholars. These graffiti marks are the one evolved or transformed from Indus script and served as a precursor to the emergence of Brahmi script. Therefore, these graffiti marks cannot be set aside as mere scratches. Like Indus script, this also could not be deciphered till date”.

The Roman artifacts found at the excavation site, in October 2018 add to the evidence of ancient trade relations between the Romans and the Pandya kingdom.

While three excavations were undertaken by the Archaeological Survey of India, the fourth excavation was undertaken by the TNAD. The fifth excavation by the latter is under way.


PS: The Indus Valley Civilization should be termed as Indus Saraswati Civilization, here we mentioned as Indus Valley Civilization only not to confuse the readers, the correct name of the civilization should be Indus Saraswati Civilization.

  1. “”4. The Aryan Invasion of India

    The second Andite penetration of India was the Aryan invasion during a period of almost five hundred years in the middle of the third millennium before Christ. This migration marked the terminal exodus of the Andites from their homelands in Turkestan.

    The early Aryan centers were scattered over the northern half of India, notably in the northwest. These invaders never completed the conquest of the country and subsequently met their undoing in this neglect since their lesser numbers made them vulnerable to absorption by the Dravidians of the south, who subsequently overran the entire peninsula except the Himalayan provinces.

    The Aryans made very little racial impression on India except in the northern provinces. In the Deccan their influence was cultural and religious more than racial. The greater persistence of the so-called Aryan blood in northern India is not only due to their presence in these regions in greater numbers but also because they were reinforced by later conquerors, traders, and missionaries. Right on down to the first century before Christ there was a continuous infiltration of Aryan blood into the Punjab, the last influx being attendant upon the campaigns of the Hellenistic peoples.

    On the Gangetic plain Aryan and Dravidian eventually mingled to produce a high culture, and this center was later reinforced by contributions from the northeast, coming from China.

    In India many types of social organizations flourished from time to time, from the semidemocratic systems of the Aryans to despotic and monarchial forms of government. But the most characteristic feature of society was the persistence of the great social castes that were instituted by the Aryans in an effort to perpetuate racial identity. This elaborate caste system has been preserved on down to the present time.

    Of the four great castes, all but the first were established in the futile effort to prevent racial amalgamation of the Aryan conquerors with their inferior subjects. But the premier caste, the teacher-priests, stems from the Sethites; the Brahmans of the twentieth century after Christ are the lineal cultural descendants of the priests of the second garden, albeit their teachings differ greatly from those of their illustrious predecessors.

    When the Aryans entered India, they brought with them their concepts of Deity as they had been preserved in the lingering traditions of the religion of the second garden. But the Brahman priests were never able to withstand the pagan momentum built up by the sudden contact with the inferior religions of the Deccan after the racial obliteration of the Aryans. Thus the vast majority of the population fell into the bondage of the enslaving superstitions of inferior religions; and so it was that India failed to produce the high civilization which had been foreshadowed in earlier times.

    The spiritual awakening of the sixth century before Christ did not persist in India, having died out even before the Mohammedan invasion. But someday a greater Gautama may arise to lead all India in the search for the living God, and then the world will observe the fruition of the cultural potentialities of a versatile people so long comatose under the benumbing influence of an unprogressing spiritual vision.

    Culture does rest on a biologic foundation, but caste alone could not perpetuate the Aryan culture, for religion, true religion, is the indispensable source of that higher energy which drives men to establish a superior civilization based on human brotherhood.”

  2. 77:5.10.
    “This center of civilization was situated in the region east of the southern end of the Caspian Sea, near the Kopet Dagh. A short way up in the foothills of Turkestan are the vestiges of what was onetime the Adamsonite headquarters of the violet race. In these highland sites, situated in a narrow and ancient fertile belt lying in the lower foothills of the Kopet range, there successively arose at various periods four diverse cultures respectively fostered by four different groups of Adamson’s descendants. It was the second of these groups which migrated westward to Greece and the islands of the Mediterranean. The residue of Adamson’s descendants migrated north and west to enter Europe with the blended stock of the last Andite wave coming out of Mesopotamia, and they were also numbered among the Andite-Aryan invaders of India.”
