Madame de Montespan,
Memoirs of Madame la Marquise de Montespan…

I said to him one day that my quarrel with him was that he did not look after himself, that he ignored all his own worth, treated himself with no more respect than a mere clerk; that he was the indispensable man, the right hand of the King, his eye of vigilance in everything, and the pillar of his business and his finance. Without being precisely what one would call a modest man, M. Colbert was calm of mind, and by nature without pose or presumption. ”
