A triskelion is like a special picture that has three arms coming out of the center. Imagine drawing a dot in the middle of a piece of paper and then drawing three curved lines that start at the dot and go outwards in different directions. These lines make the arms of the triskelion.
The triskelion is an ancient symbol that has been used by many different cultures throughout history. Some people think it looks like a three-legged spider or a little whirlpool.
In ancient times, people believed that the triskelion symbolized many different things. Some people thought it represented the sun, because the arms looked like rays of sunlight. Others believed it represented the Trinity in Christianity, which is the Father, the Son, and the Holy Spirit.
Today, you might see the triskelion used as a logo for different companies or groups. For example, the Isle of Man, a small island country near the United Kingdom, uses the triskelion as their national symbol.
