==Anthropology== Julian Pitt-Rivers reports in his study of Alcalá de la Sierra, the belief that village children can be stolen by an outsider, called el sacamantecas, disguised as a beggar or a trader, who is hired by a rich man whose ill child can only be cured with the blood of healthy babies. The practice of blood donation lent credence to the myth.
