The Calibres de France ("French calibers") was a system of standardization of cannons in France, established by King Francis I of France from about 1525.[1] The objective was to simplify and codify cannonry, in order to facilitate production.[1] On 26 September 1526, Francis I wrote about the artillerye de mon calibre ("Artillery of my caliber"), and an even earlier mention is known from 1512.[1] The Calibres de France were formalized in an ordinance of 1552.[2]
Six standard sizes were defined: the cannon (Canon), the "grand" culverin (Grande couleuvrine), the "bastard" culverin (Couleuvrine bâtarde), the "middle" culverin (Couleuvrine moyenne), the Falconet (Faucon), and the (Fauconneau).[1]
The system was expanded by an ordinance dated 27 November 1572, and an edict dates December 1601.[1]
The 6-guns Calibres de France system was still in place at the time of Louis XIII, which was later developed to an 18-guns system.[3]
The system was phased out with the Keller system in 1666, and the De Vallière system on 7 October 1732.[3]
