[A monstrous birth in the Middle Ages: the "Salernitan brother"]. / Une naissance monstrueuse au Moyen Age: le "frère de Salerne".

Gilles de Corbeil (XIIth century) reports the strange medical case of the "Salernitan brother", a monster born together with a normal child. This disorder is said to be typical of Salernitan women. The phenomenon which is still commented on by physicians in the following centuries is rather difficult to explain for it seems to depend on both scholarly medicine and popular beliefs.
