Infinity Symbol History

The infinity symbol, which we know today as a sideways figure eight (∞), was introduced by English mathematician John Wallis in 1655. Before Wallis, however, mathematicians, philosophers, and theologians had pondered the concept of infinity for centuries.

The ancient Greeks, for instance, had philosophical debates about the concept of the infinite, even though they didn’t have a symbol for it.

The history of the infinity symbol (∞) is as fascinating as its applications are varied. This symbol, which represents the concept of something unlimited or endless, has roots that stretch back several centuries and have evolved in both its meaning and its use over time.

  • Origin in Mathematics: The modern infinity symbol was introduced in 1655 by the English mathematician John Wallis. Wallis did not explicitly explain his choice of the symbol, but it is commonly believed that it is derived from the Roman numeral for 1000 (‘CIƆ’ or ‘M’), sometimes used to denote “many.” Another theory suggests that it could be a variant of the Greek letter omega (Ω), the last letter in the Greek alphabet, often used to symbolize the end or limit.
  • Adoption in Mathematical Notation: The infinity symbol gradually became a standard part of mathematical notation after Wallis introduced it. It represents an unbounded limit, infinity in calculus, and endless processes in various branches of mathematics. Its conceptual and visual appeal helped it gain a permanent place in mathematicians’ lexicon.
  • Symbolic Usage: Beyond mathematics, the infinity symbol has taken on symbolic meanings in various cultural contexts. In philosophical, spiritual, and artistic expressions, it often represents eternal love or continuity. In metaphysical discussions, it conveys the nature of infinity as it relates to space, time, and divinity.

Wallis did not provide a clear explanation for his adoption of this symbol, which has led to various theories about its origin.
  • Possible Influences and Theories:
  • Roman Numerals: One popular theory suggests that the symbol may have been derived from the Roman numeral for 1000, which was represented as “CIƆ” or sometimes as “M. The numeral CIƆ, when used in medieval manuscripts, denoted “many,” or an indefinitely large number.
  • Greek Letter Omega (Ω): Another theory posits that the symbol could be a variation of the Greek letter omega, the last letter of the Greek alphabet, often used to represent the end or the ultimate limit of a set.
  • Ouroboros and Lemniscate: The shape of the symbol, a sideways figure eight, also bears a resemblance to the ouroboros, an ancient symbol depicting a serpent or dragon eating its own tail, representing the cyclical nature of life and eternity. The mathematical term “lemniscate,” used to describe the infinity symbol’s shape, derives from the Latin for “ribbon,” reflecting its continuous loop.
  • Standardization in Mathematical Notation: Over the centuries, the infinity symbol gained traction and became a standardized notation within mathematical writings to denote endlessness or boundlessness, particularly in integrals and series in calculus.
