The church of St Paul St Louis on the Rue Rivoli was constructed in its current form in the 17th century and the first mass there was celebrated by the Cardinal Richelieu on 9 May 1641. It has a beautiful domed ceiling and the richly carved and decorated interior is all of the finest stone.
Cardinal Richelieu coined the phrase éminence grise as a euphimism for a power broker who works behind the scenes in reference to his discrete right hand man François Leclerc du Tremblay, a Capuchin Friar who acted as his agent and confidant. The sobriquet referred to the traditional grey cloak worn by the Capuchins.
Anyway, I thought that the black and white photo I took helped to highlight the interior design and turned the church itself into an éminence grise in the literal sense; a twist which I thought most Jesuitical of me and one of which I am sure Cardinal Richelieu would approve.
