The discovery of his skeleton under a Leicester parking lot has thrust King Richard III back in the spotlight after 530 years, kindling a new fascination with the much-maligned 15th-century ruler. But he’s not the only English monarch by that particular forename whose remains have recently found their way under researchers’ microscopes. French scientists have analyzed the mummified heart of his predecessor, Richard I, which has been enshrined in a Rouen church since his death in 1199.
Everyone wanted a piece of Richard I after his death in 1199 at age 41. Nicknamed the Lionheart for his battlefield bravery and military shrewdness during the Third Crusade, the medieval king met his end while inspecting a French castle he’d besieged. A crossbow bolt pierced his shoulder, and the wound apparently turned gangrenous—though some would later claim the arrow was dipped in poison.
Richard’s cadaver was then partitioned, as was the custom for royals during the Middle Ages. His entrails were buried at Châlus, where he died, and his body was interred beside his father, Henry II, at Fontevraud Abbey in northern France. As for the king’s heart, it was embalmed, enclosed in a lead box and entombed in the Notre-Dame cathedral in Rouen, then the English base in occupied Normandy.
After centuries in obscurity, the heart resurfaced during excavations at the church in 1838. Any doubts about its contents were quickly put to rest by a straightforward inscription on the box, written in characters typical of Richard’s era: “Here is the heart of Richard, king of England.” A local historian unsealed the container and found a brownish-white powder inside—all that remained of the Lionheart’s heart.
But the organ’s sorry state didn’t deter French researchers, who subjected it to a biomedical analysis using modern forensic techniques. Writing in the most recent issue of the journal Scientific Reports, they reveal that the king’s embalmers preserved his remains with an eclectic mix of agents, including daisy, myrtle, mint, incense, mercury and frankincense. After treatment with these substances, the heart was wrapped in linen and sealed for eternity in the lead box.
According to lead researcher Philippe Charlier, a forensic scientist at the Raymond Poincaré hospital in France, the embalming materials were all chosen for either practical or symbolic reasons. Mercury, for instance, helped prevent the heart from decomposing, while frankincense was likely included for its fragrance and to draw parallels between Richard and Jesus Christ. The use of daisy and incense was particularly striking because these ingredients have never been detected in any other embalmings, the researchers noted in their paper.
Why did medieval apothecaries take such pains to preserve and anoint the dead king’s heart? “The heart is a symbol not of love at that time, but of the soul,” Charlier explained. “The conservation of this organ and its deposit in an important place was an important political gesture.”
