L'Horganiste, 24-pound cannon dating back to the reign of Louis XV

L'Horganiste is a bronze 24-pound cannon created in Lyon in 1746 by founder Jean II Maritz, Master of the Foundries of France
The arrangement of decoration around the entirety of the firearm aligns with the royal order of October 7, 1732, and this piece is signed by Jean-Florent de Vallière (1667–1759).
This rich decoration is placed in such a way that the tailpiece has been sculpted to depict a Nemean lion. The first reinforce bears the French coat of arms and the sun, given that it was the king's personal emblem, along with the motto "NEC PLURIBUS IMPAR (Not Unequal to Many)." The dolphin-shaped handles are attached to the second reinforce. Finally, the barrage bears the coat of arms of the Grand Master of the Artillery, the weapon's motto Ultima Ratio Regum (The Last Argument of Kings) and the name of each part.
