The embassy set out for France in 1686, accompanying the return of the 1685 French embassy to Siam of Chevalier de Chaumont and François-Timoléon de Choisy on two French ships. The embassy was bringing a proposal for an eternal alliance between France and Siam. It remained in France from June 1686 to March 1687. Kosa Pan was accompanied by two other Siamese ambassadors, Ok-luang Kanlaya Ratchamaitri and Ok-khun Si Wisan Wacha, and by the Jesuit Father Guy Tachard. Kosa Pan's embassy was met with a rapturous reception and caused a sensation in the courts and society of Europe. The mission landed at Brest, France before continuing its journey to Versailles, constantly surrounded by crowds of curious onlookers. The "exotic" clothes as well as manners of the envoys, together with a special "machine" that was used to carry King Narai's missive to the French monarch caused much comment in French high society. The machine is called butsabok in Thai. Kosa Pan's great interest in French maps and images was noted in a contemporary issue of the Mercure Galant.
Presents
The embassy brought many gifts to present to Louis XIV, including gold, tortoise shells, fabrics, carpets, more than 1,500 pieces of porcelain, and lacquer furniture. Two silver Siamese cannons were presented to Louis XIV; they were seized by French revolutionaries in 1789 to be used in the Storming of the Bastille.
Purchases
The embassy ordered vast amounts of French products to be shipped to the Siamese court: 4,264 mirrors similar to those of the Galerie des Glaces were ordered to decorate Narai's palace, through Jean-Baptiste Colbert to the factory of Saint Gobain. Among other orders were 160 French cannons, telescopes, glasses, clocks and various velvet pieces and crystal decorative elements. They also ordered two geographical globes, inscribed in Thai by French artisans, as well as seven carpets from the Savonnerie manufactory.
Influences
The Siamese Embassy to France in 1686 had brought to the Court samples of multicolor Thai Ikat textiles. These were enthusiastically adopted by the French nobility to become Toiles flammées or Siamoises de Rouen often with checkered blue-and-white designs. After the French Revolution and its repudiation of foreign luxury, the textiles were named "Toiles des Charentes" or cottons of Provence. A fragmentary Siamese account of the mission compiled by Kosa Pan was discovered in Paris in the 1980s. The embassy's encounter with Louis XIV is depicted in numerous paintings of the period. The embassy of Kosa Pan was soon followed by another in 1688, led by Ok-khun Chamnan.
