King St. Louis IX, last instruction to his son: “If God send thee adversity, receive it in patience and give thanks to our Saviour and bethink thee that thou hast deserved it, and that He will make it turn to thine advantage. If He send thee prosperity, then thank Him humbly, so that thou becomest not worse from pride or any other cause, when thou oughtest to be better. For we should not fight against God with his own gifts.” (Memoirs of the Crusades, translated by Sir Frank Marzials, Joinville’s Chronicle, pg. 321, King St. Louis IX’s last instructions to his son, Pub. 1908)
