Okay, imagine that you are playing pretend and you are a doctor. A long time ago, there were some people who wanted to be doctors too! But they didn't just go to school like we do now. They went to a special place called the "College of Aesculapius and Hygia."
Now, Aesculapius and Hygia are not real people, but they were imaginary gods who were thought to be the ones who helped doctors heal people. The college was named after them to honor their importance.
When people went to the College of Aesculapius and Hygia, they learned all about how to help people who were sick or hurt. They learned how the body works, what medicines to use, and how to do surgery when necessary.
It was a really important place because doctors were needed to help people stay healthy and feel better. And the College of Aesculapius and Hygia was like a special school where people could learn how to do that!
