Since the end of the afternoon, the body of Henri IV had lain on a bed in the small cabinet of the queen. Around midnight, his blood-stained garments were removed. The body was washed and dressed in a white satin doublet, and then was taken to his chamber and placed on the bed. The following day, the king's 18 doctors and 13 surgeons carried out the autopsy. All noted the good general condition of the corpse, and agreed that the second wound "was the sole and necessary cause of death."
Embalming of the body began immediately afterwards. The king's entrails were placed in a vessel and transported to Saint-Denis on 18 May. His heart was placed in a lead urn set in a heart-shaped silver reliquary and, in accordance with his wishes, was transported by Montbazon and some 400 knights to the Jesuit college of La Flèche. Once it was embalmed, the king's body was placed in a coffin and laid out on a bed covered with gold drapery in the Grande Chambre de Parade in the Tuileries. The king lay in state for eighteen days, during which one hundred low masses and six high masses were said daily. On 10 June, the casket was moved to the Salle des Caryatides and laid out on a bed of state on which was placed an effigy of the deceased sovereign.
The rites ended with the actual funeral. On 25 June, Louis XIII sprinkled holy water on his father's body. On 29 June, a procession of all of the State's constitutional bodies accompanied the body of Henri IV to Notre Dame, where an initial ceremony was held. The next day, Henri was taken to saint-Denis, the royal necropolis, and on 1 July 1610, the king was interred there. Meanwhile, the body of Henri III had been hastily brought from Compiègne and placed in the vault in order to symbolise the royal succession.
