Legend says that the stone was used as a pillow by Jacob in biblical times, it is thought it was brought to Scotland in the 9th century, and it was used as part of the crowning ceremonies of the kings of Scotland. It was stolen by Edward I of England in 1296 and remained under the Coronation Throne is Westminster Abbey in London for 700 years. It was finally returned to Scotland in 1996.
Declaration of Arbroath Plaque. This document basically declared that the rule of Scotland was not determined by the pope, or even by God, but by the people of Scotland. It stated that Scotland had always been free (longer than England, in fact), and that any so-called king that threatened to deprive men of their natural rights did not deserve a throne. Robert the Bruce had set them free and was their choice, and Bernard begged the pope to recognize him which he did.
