A brachycephalic is defined as a person who has a broad head. A brachycephalic person has a cephalic index over 80 per cent. Cephalic index is calculated by dividing the cranial breadth by the cranial length and multiplying the answer to that ratio by 100. The cephalic index was defined by Anders Retzius. He was born in the year 1796 and died at the age of 64 in the year 1860. Retzius was a professor of anatomy from Sweden. He was the first person to use it in the course of the study of the subject matter of physical anthropology. He used it to classify the remains of human beings from the ancient times, which were discovered in Europe.
