I may have got something:
The infinity symbol
John Wallis introduced the infinity symbol to mathematical literature.The infinity symbol is sometimes called the lemniscate, from the Latin lemniscus, meaning "ribbon". John Wallis is credited with introducing the symbol in 1655 in his De sectionibus conicis.[2][3] One conjecture about why he chose this symbol is that he derived it from a Roman numeral for 1000 that was in turn derived from the Etruscan numeral for 1000, which looked somewhat like CIƆ and was sometimes used to mean "many." Another conjecture is that he derived it from the Greek letter ω (omega), the last letter in the Greek alphabet.[4] Also, before typesetting machines were invented, ∞ was easily made in printing by typesetting the numeral 8 on its side.
The infinity symbol is available in standard HTML as ∞ and in LaTeX as \infty. In Unicode, it is the character at code point U+221E (∞), or 8734 in decimal notation.
