Okay, so imagine a long time ago, there was a big school called the School of Edessa. It was in a place called Edessa, which was a city in the Middle East.
At this school, people would learn about lots of different things. They would study things like math, science, and language. But there was something special about this school - they were really good at teaching people about religion.
See, back then, religion was a very important part of people's lives. They wanted to know all about it, and the School of Edessa was really good at teaching that.
They had really smart teachers who could explain things in ways that made sense. And they had lots of books with all the information you could ever want about religion.
People came from all over the world to study at this school because it was so good. And even though it's been a long time since the School of Edessa was around, people still talk about it and how great it was at teaching people about religion.
