What is old caledonians?

As an AI language model, I don't understand the specific context of "old caledonians."

However, the term "Caledonian" has historically been used to refer to the people and region of Scotland. The name comes from the Roman word "Caledonia," which was used to describe the area north of the River Forth.

In ancient times, the Caledonians were a confederation of tribes that lived in what is now Scotland. They were known for their fierce resistance to Roman invasion and were considered to be a formidable opponent by the Roman army.

During the Middle Ages, Scotland was unified under the rule of the Scottish kings, and the term "Caledonian" fell out of use. However, the legacy of the ancient Caledonians can still be seen in Scottish culture today, from the Highland Games to traditional Scottish dress and music.
