Why would this seal feature person on the horse?

Please provide me with more information! I need to know what seal you are referring to in order to tell you why it might feature a person on a horse.

For example, tell me:

* What does the seal look like? (Is it a coat of arms, a city seal, a company logo?)

* Where is this seal found? (Is it on a document, a building, a website?)

* What is the context of the seal? (Is it related to a historical event, a particular profession, a specific location?)

Once I have this information, I can help you understand why the seal might feature a person on a horse.
