Monsieur de Callières,
On the manner of negotiating with princes
(1919)
“ The Regency needed an intelligence of the highest order, a capacity without limit, a clear insight into the character of persons and events, and an indefatigable activity which would increase at every new demand made by the interests of state—all these united in the person of a prince at once just, lovable, beneficent, whose character might earn for him the title of a veritable father of his country. ”
