BRAMHI SCRIPT IN ASHOKA STAMBHA INSCRIPTION (249 BCE) LUMBINI, NEPAL



Number Words In The Brahmi Script Inscription Of Ashoka Stambha (249 BCE),Lumbini

  • Brahmi Script Devanagari Script

  • jL;

  • c7-efluo]_



Brahmi Numerals

  • The best known Brahmi numerals used around 1st Century CE.



Some Numerals In Some Other Ancient Inscriptions

  • First Phase :

  • Numerals for 4, 6, 50 and 200

  • No numeral for 5 but for 50

  • Second Phase :

  • Numerals for 1, 2, 4, 6, 7, 9, 10, 20, 80, 100, 200, 300, 400, 700; 1,000; 4,000; 6,000; 10,000; 20,000.

  • No Numeral for 3 but for 300

  • Third Phase:

  • Numerals for 3, 5, 8, 40, 70, …, 70,000.



Hypotheses About The Origin of Brahmi Numerals

  • The Brahmi numerals came from the Indus valley culture of around 2000 BC.

  • The Brahmi numerals came from Aramaean numerals.

  • The Brahmi numerals came from the Karoshthi alphabet.

  • The Brahmi numerals came from the Brahmi alphabet.

  • The Brahmi numerals came from an earlier alphabetic numeral system, possibly due to Panini.

  • The Brahmi numerals came from Egypt.



Something More About Brahmi Numerals

  • The symbols for numerals from the Central Asia region of the Arabian Empire are virtually identical to those in Brahmi.

  • Brahmi is also known as Asoka, the script in which the famous Asokan edicts were incised in the second century BC.

  • The Brahmi script is the progenitor of all or most of the scripts of India, as well as most scripts of Southeast Asia.

  • The Brahmi numeral system is the ancestor of the Hindu-Arabic numerals, which are now used world-wide.



EPIGRAPHY VERSUS VEDIC MATHEMATICS

  • Total lack of Brahmi and Kharoshthi inscriptions of the time before 500 BCE

  • Much of the mathematics contained within the Vedas is said to be contained in works called Vedangas.

  • Vedic Period : Time before 8000 /1900/ BCE etc.

  • Vedangas period: 1900 – 1000 BCE.

  • Sulvasutras Period : 800 - 200 BCE.

  • Origin of Brahmi script : Around 3rd century BCE

  • No knowledge of existence of any written script during the Ved- Vedangas period.

  • Numerical calculation based on numerals(?) during the so-called early Vedic period highly unlikely.





WHY DO WE FOCUS ON THE NUMBERS



Lichhavian Number 1 to 99



Lichhavian Numbers and Major Number Systems



Table I(A)



Something About Lichhavian Number System

  • Lichhavian numerals for 1, 2 and 3 consist of vertically placed 1, 2 and 3 horizontal strokes like the Chinese 14th century BCE numerals, Brahmi numerals of the 1st century CE and Tocharian numerals of the 5th century CE.

  • The Lichhavian numerals for 1, 2, 3, 40, 80 and 90 look somewhat similar to the corresponding Brahmi numerals.

  • There is a striking resemblance between the Lichhavian and Tocharian numerals for, 1, 2, 3, 20, 30, 80 and 90; just like many Tocharian albhabet.

  • Several other Tocharian numbers appear to be some kind of variants of the Lichhavian numbers.

  • Each of the three systems uses separate symbols for the numbers, 1, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 1000, … .



Something About Lichhavian Number System

  • Compound numbers like 11, 12, …, 21, 22, …, 91, 92, … are represented by juxtaposing unit symbols without ligature.

  • Hundred symbol is represented by different symbols and is often used with and without ligature .

  • Non-uniformity in the process of forming hundreds using hundred symbol and other unit symbols.

  • Several variants of numerals are found during a period of several centuries.

  • Hundred symbol is represented by different symbols and is often used with and without ligature .

  • Non-uniformity in the process of forming hundreds using hundred symbol and other unit symbols.

  • Several variants of numerals are found during a period of several centuries.

  • Available Lichhavian numbers are lesser than 1000.

  • No reported number lies between 100 and 109, 201 and 209, …, 900 and 909. Numbers for 101, 102, …, 109, 201, 202, …, 209, …, 901, 902, …, 909 are missing



Something About Lichhavian Number System

  • Arithmetic of Lichhavian is not known

  • Formation of two and three indicate vertical addition, while formation of 11, 12, …, indicate horizontal addition in the expanded form – a kind of horizontal addition.

  • Lichhavian system is additive

  • Lichhavian system is a decimal system.

  • Liichhavian system is multiplicative:

  • numeral for 4 attached to symbol for 100 by a ligature stands for 400 to be read as 4 times 1 hundred

  • numeral for 5 attached to symbol for 100 by a ligature stands for 500 to be read as 5 times 1 hundred

  • numeral for 6 attached to symbol for 100 by a ligature stands for 600 to be read as 6 times 1 hundred,

  • Existence of some kind of arithmetic in Tocharian number system may provide some clue in this direction.



Something About Lichhavian Number System

  • Lichhavian numbers like

  • 462

  • is to be read as

  • 4 times hundred or 4 hundreds and 1 sixty and 2 ones

  • or, 4(100) 1(60) 2(1) = 4100 + 1  60 + 2  1

  • and 469

  • is to be read as

  • 4 times hundred or 4 hundreds and 1 sixty and 1 nine

  • or, 4(100) 1(60) 1(9) = 4100 + 1  60 + 1  9.



COLLECTION

  • COLLECTION

  • CLASSIFICATION

  • COMPREHENSION

  • MANIPULATION

  • MANIFESTATION

  • MYSTIFICATION









One Possible Solution

  • Adopt a uniform system in which the hundred symbol attached to one of the first nine numbers is considered as the next hundred: e.g.,

  • as 200

  • as 300

  • as 500

  • as 600

  • as 700

  • 1000 would look like



Best Solution

  • Adopt an internationally accepted uniform system in which the hundred symbol attached to one of the first nine numbers is interpreted as the same hundred as the attached unit number : e.g.,

  • as 100

  • as 200

  • as 400

  • as 500

  • as 600

  • 1000 would have a new symbol



  • The interpretation of the number-symbol

  • in the number

  • as 100 and as 200 by the epigraphers.

  • The interpretation of the number

  • in the Changu Narayan inscription as

  • the number 386.



CRITICAL ISSUES ?

  • The unfortunate interpretation of the same symbol

  • both as the number 300 as well as the number 500 by the same experts in a large number of inscription (as can be seen from the earlier slides).

  • The hesitation of a great section of epigraphers and ancient history of Nepal in rectifying their old interpretation of the number on the basis of a logical reason and the procedure followed by many ancient civilizations in forming such numbers.



WHAT IS TO BE DONE?

  • Since Changu Narayan Inscription is considered as the starting point for interpolating and extrapolating the ancient history; and hence that of the whole history of Nepal, the date

  • inscribed in the inscription and read even today as the number 386 needs a careful reexamination on the basis of various facts pointed so far.

  • We must first of all decide



WHAT IS TO BE DONE?

  • Since the number of kings and the average period of the rule of known and unknown kings vary from expert to expert, the same process of interpolation and extrapolation of available information yield totally unacceptable imaginary inferences. This is further aggravated by interpretations of the Samvat 386 such as

  • 329 AD by Bhagwan Indrajit

  • 464 AD by Babu Ram Acharya

  • 496 AD by Levi

  • 705 AD by Flit.

  • In such a situation, we have to decide

  • “ Whether we have to change these dates, at least, to

  • 229 AD, 364 AD, 396 AD and 605 AD ?”



WHAT IS TO BE DONE?

  • Collection of information, classification and comprehension become meaningless at a time when manifestation of unreasonable manipulation takes place in the form of obvious mystification as can be seen from the following table:
