Rampant Lions in European Heraldry

[OC Richard]

I used to have that book! It was enormous.

It was an interesting read on a rainy day, but I ended up giving it away.

Wiki says this about the lion on the Scottish flag

a lion rampant Gules armed and langued Azure

(sky blue claws and tongue; it seems standard to have the claws and tongue a different colour from the rest of the lion).

What I find interesting is that the Scottish flag always seems to use the same drawing of a lion, while I see different styles regularly appearing on other flags, suggesting that it's not any rampant lion, but a specific drawing, that's associated with each flag, whatever the rules of Heraldry might be.
