Pediculosis seems to have afflicted humans since the most ancient times
and lice have been found in several ancient human remains. Examination
of the head hair and pubic hair of the artificial mummy of Ferdinand II
of Aragon (1467-1496), King of Naples, revealed a double infestation
with two different species of lice, Pediculus capitis, the head louse,
and Pthirus pubis, the pubic louse. The hair samples were also positive
for the presence of mercury, probably applied as an anti-pediculosis
therapy. This is the first time that these parasites have been found in
the hair of a king, demonstrating that even members of the wealthy
classes in the Renaissance were subject to louse infestation
