Myth of Tamil Brahmi

Myth of Tamil Brahmi and script.
There is Ashokan Brahmi standardised by Ashoka found all over India. And there is tamil Brahmi. Let us see the genesis of Tamil Brahmi.
Tamil Brahmi Genesis
The early Brahmi inscriptions posed a greater challenge on account of their archaic characters and orthographic conventions, which were different from the original Brahmi used for Prakrit. The challenge seemed insuperable even to the most competent among the pioneering epigraphists. The major breakthrough in the decipherment of the cave inscriptions of Tamil Nadu came with K.V. Subrahmanya Aiyer (1924). He was the first to recognise that these are inscribed in Brahmi, but with certain peculiarities and new forms of letters, due to its adaptation for the Tamil language which has sounds (phonetic values) not known to the Prakrit (Indo-Aryan) language and northern Brahmi script. Yet, this lead was not seriously followed and was soon forgotten. Even Subrahmanya Aiyer did not pursue his line of enquiry to its logical conclusion. Other scholars like V. Venkayya and H. Krishna Sastri were constrained by the assumption that all Brahmi inscriptions were invariably in Prakrit or Pali, as Brahmi was used predominantly for Prakrit in all other regions of India from the Mauryan (Asokan) period. Their readings failed to convey any meaning.

Irvatham Mahadevan
Now enter the picture Irvatham Mahadevan an administrator-turned scholar, we have tamil Brahmi. By reviving Subrahmanya Aiyer's early decipherment and reading and at the same time more systematically studying these inscriptions in all their aspects, including palaeography, orthography and grammar, and seeking corroboration from the Sangam Literature and Tolkappiyam, the basic work on Tamil grammar. Mahadevan has virtually re-deciphered these inscriptions and shown them to be inscribed in Tamil. Hence the name "Tamil-Brahmi," one variety of the Brahmi script.

Characteristics of Tamil Brahmi
1.Brahmi script was adapted and modified to suit the Tamil phonetic system.
2.Palaeographic changes were made to suit the Tamil language, with the omission of letters for sounds not present in the Tamil language and by additions to represent sounds in Tamil that are not available in Brahmi.
3.All but four of the 26 letters are derived from Brahmi and have the same phonemic values.
4.Even these four - i.e., l,l, r, n - are adapted from the letters with the nearest phonetic values in (Asokan-) Brahmi, i.e., d, l, r, n.
5.Letters were also modified with a special diacritic mark, viz., the pulli (dot). These are reflected in the development of the Tamil-Brahmi in three stages (TB I, II and III):
Stage I
1. Inherent a (short-medial vowel) was absent in the consonants
2. strokes (vowel notations) were used for both the short and long medial a, and hence the need for the reading of consonants with reference to context and position;
Stage II
when the stroke for medial a marked only the long a;
Stage III
1. when the use of diacritics like the pulli was introduced for basic consonants and for avoiding ligatures for consonant clusters (as in Simhala-Brahmi).
2.The pulli was used also for distinguishing the short e and o from the long vowels, for the shortened - i and -u (kurriyalikaram and kurriyalukaram)
3.The pulli used for the unique sound in Tamil called aytam, all of which are unknown to the Indo-Aryan ( Prakrit and Sanskrit).

It is the recognition of the absence of the inherent vowel a (short) in the early phases, e.g. ma, ka, na with strokes or medial vowel notations, which are actually to be read as ma, ka, n (the inverted J symbol for the nominal suffix `an' characteristic of Tamil), and the addition of the pulli as a diacritic, that provided the key to the whole re-decipherment. Herein lies the basic contribution of Mahadevan to the study of the script and alphabet. That these findings are corroborated by the phonetic rules of the Tolkappiyam.

Above passages gives the Genesis and Characteristics of Tamil Brahmi
Where are these Incriptions

1.Pottery inscription in Tamil-Brahmi giving the name Catan. 1st century A.D. Found at Quseir-al-Qadim on the Red Sea coast of Egypt.

2.Rock-cavern inscription in Jambai 2nd Century AD.

Let us see what spoils such a great discovery

1. Pulli TheoryScholars have observed two notational systems of Brahmi for writing Tamil. The first system is older than the second and the latter is very close to the Asokan Brahmi system. In the first system the short medial, a, is marked by a short horizontal stroke. In the second system the same mark indicates a long medial a. For example, scholars once used to read a certain word as maakaana following the second system. It did not make much sense. When the first system was used to read the inscription, the meaning became clear. The same word was read as makan, a common Tamil word for son. These two systems of Brahmi are different from the Tamil Pulli system described in Tholkappiam. The earliest stone inscription in the Tamil script is found at Vallam near Chinglepet and it belongs to the early seventh century A.D.There the dot over the pure consonants can be clearly seen. In the numerous inscriptions found on rock-shelters on hillocks near Madurai, scholars have failed to observe the Pulli in any of the inscriptions. The occurrence of the Pulli is closely linked with the date of Tholkappiam believed to be the oldest Tamil work. The late occurrence of the Pulli in Tamil inscriptions will indicate either the late date for the tholkappiam or prove Tamil Brahmi theory as false.
2. Lack InscriptionsFor all the theories about inscriptions , we find only two or three inscriptions in the period mentioned 300BC to 500AD. Almost all the inscriptions are some grafitti. If the sangam literature and Tholkappiam if assumed are from this period then there should be flurry of inscriptions the absence show that written culture was not widespread.
3. Inconsistencies of two Tamil brahmi and Tamil Pulli systems.The second system is closer to Ashoka Brahmi then the first one. And pulli does not show up until 7th century AD. Some scholars have even argued that Ashoka brahmi came from Tamil Brahmi, but that is not a creditable argument. Only few inscription sometimes only one inscription have been cited to show they are different. Anyone can see there will be some changes even if same person writes and the script surviving great distances with only few variations is itself miracle. So these differences are just few errors crept into the writing not a seprate script.
4. Citing evidences where tamil was not present
   Mahadevan has been citing the southern Brahmi script found in Karnataka and Andhra to prove his theory especially Bottiporulu inscription. Which cannot be considered in the context of tamil. Many of the inscriptions dates not verified by competing authority. many references have been heresay and preliminary data on the first sighting. Many of the inscriptions are handcopied which again can introduce errors.
5. Regional variations not surprising
   There are number of regional variations in Brahmi itself. Northern brahmi, southern brahmi , sinhala brahmi and others. In southern brahmi itself in bottiporulu inscription simultaneouly different variations have been found.
6. Sinhala Brahmi
   Tamil brahmi is very similar to Sinhala brahmi. Here Mahadevan will claim sinhala brahni came from tamil brahmi, but evidence shows otherwise. Until 3nd century AD the tamil brahmi and srilankan brahmi are carbon copy of each other. only with advent of pallavas the script went in different ways.
7. Scientific evolution of Brahmi
   Brahmi's limitation in phonetics in each region of India was overcome by adding megalithic symbols over the brahmi script that is why we have so many scripts in India. These are called vowel markers. This nothing new.
8. Literary works at later period
   The written literture comes from later period of 8th century AD , it reaches a peak in 12-13th century AD. Writting seems to have started around 6th century AD during Pallava region.

So a normal evolution of scripts are taken in the arguement and has been cited reason for uniqueness of the script. Same type of evoluation has taken in other parts of India is downplayed and the arguement is made that only tamil has them is false. In short the Tamil Brahmi is an attempt to stretch the antiquity of tamil and also
