The general image is that a snake (or dragon) is devouring its tail, producing a ring (sometimes in the shape of a twisted pattern, that is, the Arabic numeral "8"), whose name means "self-devourer". This symbol has always had many different symbolic meanings, among which the most accepted are "infinity" and "cycle".
In addition, the snake is also a common symbol in religion and mythology, and an important emblem in alchemy. In modern times, some psychologists (such as carl jung) think that Ouroborosaurus actually reflects the prototype of human psychology.
On some occasions, snakes will be depicted as half bright and half dark, just like the pattern of yin and yang, symbolizing the bipolar concept of everything; More importantly, although these two opposing forces are incompatible, they are not in a confrontational position at the same time.
The serpent and infinity:
The concept of infinity possessed by snakes is also related to the concept of infinity in mathematics. In fact, the real source of the shape of the mathematical infinite symbol "∞" has not been clarified.
Aristotle (384-322 BC), an ancient Greek philosopher, believed that infinity could exist, because a finite quantity is infinitely separable and cannot reach extremes, but infinity is universally acknowledged as unattainable.
/kloc-in the 20th century, a great Indian mathematician, Bascara, appeared, and his concept was close to that of modern theorization.
The symbol of putting 8 horizontally as ∞ to represent infinity was first put forward in john wallis's paper Arithmetic Infinity (published in 1655).
