# Infinity Symbol and Roman Numerals

The infinity symbol is a mathematical sign and this symbol indicates the concept of something endless. The symbol for infinity was created by the English mathematician John Wallis in the 17th century. Even he was the first person to use the infinity symbol, Wallis didn’t give an explanation for his choice. But there is a theory about what the symbol originated from.

1000 (one thousand) is the natural number following 999 and preceding 1001. This number is important because a millennium is a period equal to 1000 years. And it is written as M in Roman Numerals.

Except using M for 1000 in Roman Numerals System, the ancient Romans also used the symbol CIƆ or CƆ which looks like the infinity symbol. 1000 was also defined with the 21st letter of the Greek alphabet, phi. But then the symbol changed and today we use M which was derived from the Latin word mille "thousand".
