Article XXVI of the Rolls of Oléron, the Anglo-French admirality law of 1160:
If the lord of any place be so barbarous, as not only to permit such inhuman people [pirates], but also to maintain and assist them in such villainies, that he may have a share in such wrecks, the said lord shall be apprehended, and all his goods confiscated and sold, in order to make restitution to such as of right it appertaineth; and himself to be fastened to a post or stake in the midst of his own mansion house, which being fired at the four corners, all shall be burnt together, the walls thereof shall be demolished, the stones pulled down, and the place converted into a market place for the sale only of hogs and swine to all posterity.
