Romain Du Roi

Well the typeface was made in 1692 by King Louis XIV to be used as a Royal Typeface. I think this image pretty much sums what I just said.
It is used by Impremiere Royale and was first used in 1702. It was created by Philippe Grandjean. I think for the most part the typeface was supposed to be different than non-royal beings. It was used during the Age of Enlightenment and for the most part the designer had creative liberty to create what he wanted. The letters really reflect the time and elegance of his reign.
