Louis IX (1226 -1270) was a reformer of the French royal justice. He banned trials by ordeal by which the guilt was determined by death, while the innocence was proved by survival. Louis IX made himself the supreme judge to whom anyone was able to appeal to seek a judgement. Accompanied by his court, the king judged anybody, rich or poor, sitting often under a grand oak in the Bois de Vincennes. The original tree is no longer there, but the place with numerous old oaks is still magic. You may try to sit under an oak with wide-spreading branches and unleash your imagination.
