     Sebastien Truchet (1657-1729) was a noted mathematician and inventor. In typography he is noted for two very important advances: The Romain du roi typeface, and the invention of the typographic point.
     The Romain du Roi font, which was later used by Grandjean in Médailles sur les Principaux Evénements du Règne de Louis le Grand, 1702 (today can be found digitized by Frank Jalleau under the name of Grandjean), was designed by Truchet, although usually attributed to Jaugeon.
Further on, he invented the notion of the "vectorial font" by defining the characters in terms of outlines with approximation by arcs of the circle. The use of a fine grid, which was roughly the equivalent to the resolution of 2300 dpi, was an innovation of the time.
There are no Italic Romain du roi, but comprises characters that geometrically slant by deformation of their axis. A number of tables or commentaries, which are the equivalent of today's AFM's, are associated to these glyphic specifications.
