Macrocephali (Medieval bestiaries)
The Macrocephali (Ancient Greek: "long-headed people") were ancient tribes of Africans or Indians who performed artificial cranial deformation. Some ancient authors mentions such tribes also at Caucasus and in the north-east of Pontus (region). Their cultural practice of artificially shaping the skulls of their children was mentioned by Hesiod, Hippocrates, Pomponius Mela, Pliny the Elder, Valerius Flaccus, Xenophon, Strabo, and Eustathius.
