even to Coeur-de-Lion's tar-and-feather extreme
Note from the Letter Charitas by John Ruskin

'Fors Clavigera' is recurrently concerned with the careers of various heroes of medieval chivalry. The extreme authoritarian streak in Ruskin finds much to admire in the laws of Richard I, some of which he quotes in Letter 3. About to embark on the Third Crusade, Richard decreed that any of his troops found guilty of theft should be tarred and feathered and put ashore on the first land sighted. Ruskin particularly valued Richard's laws for a more admirable principle: they classed misrepresentation and deception as forms of theft.
