Okay, imagine you see a picture of a big lion with his mouth open and he has big long teeth. Now, imagine that this lion is standing on a shape that looks like a wheel with lines on it. This big lion is actually something that was made a very long time ago in a place called Mathura, which is in India.
People who lived in India a long time ago really like to make things that are pretty and also have a special meaning. This big lion with the wheel thing underneath it was actually created to represent something called the "dharma" which means a way of living that is good and true.
The artists who made this lion were very skilled and they made it out of a special kind of rock that was carved to make all of the details on the lion and the wheel. The lion is really big and strong, which is supposed to make people think about being brave and honest. The wheel under the lion is called the "dharmachakra" which means the wheel of the dharma, and it has eight spokes to help people remember the eight steps toward good living.
The Mathura lion capital is a very important piece of art and it has been seen by many people all over the world. People still talk about it today because it is very special and represents something that is very important to many people.
