Lions or Leopards

Question sent via email:
On the more older Royal coat of arms in Edinburgh, England was represented by 3 Leopards not Lions.
Is that true?

Whether we should refer to the creature as a lion or a leopard is all to do with the posture of the creature rather than the species.

French was the language of English government for a few centuries after the Norman Conquest of 1066. In a French blazon (coat of arms) a lion is always rampant (standing on its hind legs); a lion passant guardant (walking forward and facing outward toward the viewer) is always called a léopard.
