The mysterious world of ancient Greek numbers: Why did the ancients use letters to represent numbers?
Ancient Greek numerals, also known as Ionian numerals, are a system for writing numbers using the Greek alphabet. These letters are still used today in modern Greek for ordinal numbers and in contexts similar to Roman numerals. However, for common cardinal numbers, Greece adopted Arabic numerals. The origin and evolution of this number system reflects how ancient humans relied on Chinese letters to express numbers.
The linear A and B alphabet systems used by the ancient Aegean civilization demonstrated different ways of writing numbers and laid the foundation for the development of ancient Greek numerals.
Early number systems, such as the Minoan and Mycenaean Linear A and Linear B, used so-called Aegean numerals and played a key role in the formation of ancient Greek civilization. Linear numbers use unique symbols to represent powers of ten: for example, 𐄇 for 1, 𐄐 for 10, 𐄙 for 100, and so on.
The Greek alphanumeric system is based on a decimal system, assigning 1 to 9 to the first nine letters of the ancient Greek Ionic alphabet, with separate letters for each tens and hundreds.
Over time, the Greek numeral system changed from its original Acrophonic form to the current alphanumeric system. The earliest forms of ancient Greek numerical writing date back to the fifth century BC, and gradually replaced the older alphabetic system in Athens. This number system is based on the principle of addition, allowing the sum of letter values to form new numbers. For example, 241 is represented as (200 + 40 + 1), with each letter coming from a different position in the Greek alphabet.
The ancient Greeks also used special symbols to represent fractions and larger numbers, which added a lot of layers and depth to their number system.
In addition, the ancient Greek number system could express fractions, usually with a special symbol after the denominator. As time went by, the positioning symbols (keraia) in Greek documents also changed, further improving the method of representing numbers. These symbols not only make numbers more accurate, but also greatly improve their recognizability in literature.
The evolution of the number system is not just a change in numbers, but also an evolution of thought. The use of Greek numbers and their connection with letters reflects the ancient people's profound understanding of knowledge and logic.
The expression of spectacular numbers such as hundreds or thousands also led to endless explorations by the ancient Greeks. Like Archimedes, they tried to use numbers to describe the size of the universe, which enabled ancient mathematicians to begin to go beyond the limitations of single numbers and conduct more in-depth analysis of different quantities through new numerical systems. As this process unfolded, the Greek number system gradually took the form we see today.
Even in today's numerical usage, the numerical expressions of ancient Greek letters still live in some places, such as in some mathematical formulas or historical documents. Exploring the connection between these numbers and letters is not only a reflection on ancient civilization, but also a reflection on the current mathematical system.
Behind the ancient Greek numbers lies the changes in human thinking over thousands of years, which is crucial to understanding the evolution of numbers and their meanings.
When we trace back these ancient numbers, can we find a deeper connection that reveals that numbers are not only a representation of quantity, but also an extension of thinking? Perhaps this is a new perspective on understanding digital systems?
