The hair samples of Ferdinand II of Aragon (1467–1496), King of Naples, whose mummy is preserved in the Basilica of San Domenico Maggiore in Naples, showed a high content of mercury, with a value of 827ppm. Furthermore, examination using a stereomicroscope and a scanning electron microscope (SEM) of head and pubic hairs of Ferdinand II, revealed a lice infestation. The reasons for the massive presence of the mercury in the king's hair are discussed and contemporary literature regarding the use of this metal in medical therapies and in cosmetic practices is analysed. As a result, the high value of mercury in the hair of Ferdinand II can be attributed to antipediculosis therapy, applied as a topic medicament. This case represents an important finding for the history of medicine, because demonstrates that in the Renaissance mercury was applied locally not only to treat syphilis, as well attested by direct and indirect sources, but also to prevent or eliminate lice infestation.

6 They are wingless and dorsoventrally flattened insects with short antennae and poorly developed eyes. The three strong pairs of legs terminate with a spine and a claw that allow anchoring to the hairs or clothing of the host. The head louse and the body louse measure about 3mm in length and are morphologically so similar to each other, that still today some authors consider them as subspecies of P. humanus, while others prefer to see them as two separate species (N.P. Leo et al., ‘The Head and Body Lice of Humans are Genetically Distinct (Insecta: Phthiraptera, Pediculidae): Evidence from double infestations’, Heredity, 95 (2005), 34–40). Habitat differentiation probably arose when man adopted the use of clothing (R. Kittler, M. Kayser and M. Stoneking, ‘Molecular Evolution of Pediculus humanus and the Origin of Clothing’, Current Biology, 13 (2003), 1414–17). The pubic louse is about 2mm in length and is called crab louse for its big claws on the second and third pairs of legs and compacted thorax and abdomen.
