Can artificially deforming skulls cause "defects of intelligence"? The observations of a positivist anthropologist on an artificially deformed skull discovered in Naples.

We discuss a particular case of an artificially deformed skull discovered in Naples in 1892 and published in the Italian Journal of Natural Sciences by the anthropologist Abele De Blasio. To comprehend the observations of the researcher about the "defects of intelligence" caused by the artificial deformation of the skull, we will also analyze other articles in which De Blasio presented the deformed skulls of ancient Peruvian mummies.

Multiple Abnormalities in the Skull of a Prostitute. An Autopsy Report (1900).

OBJECTIVE: The study presents and comments on the publication of an autopsy report. CASE REPORT: In 1900 De Blasio published an article entitled "Multiple abnormalities in a prostitute's skull" in the "Journal of Psychiatry, Criminal Anthropology and related sciences". In this work De Blasio related anomalies at the cranial level to the presence of mental pathologies. The skull belonged to a 24-year-old prostitute who died of syphilitic hepatitis. In his article, De Blasio described the life of the woman, after which he gave a macroscopic description of the skull. De Blasio believed that the subject's amoral behavior was caused by the anomalous shape of the subject's skull. CONCLUSION: From the study, it is evident that the school of criminal anthropology influenced De Blasio's autopsy medical practice, and it is interesting to note the interpretation of anthropologists of the time who tried to describe the link between physical and behavioral anomalies.
