History of anthropology
The first use of the term "anthropology" in English to refer to a natural science of humanity was apparently in Richard Harvey's 1593 "Philadelphus, a defense of the legend of Brutus in British history", which, includes the passage: "Genealogy or issue which they had, Artes which they studied, Actes which they did. This part of History is named Anthropology."
Ethnology
Compared to ethnography, the study of single groups through direct contact with the culture, ethnology takes the research that ethnographers have compiled and then compares and contrasts different cultures.
The term "ethnologia" ("ethnology") is credited to Adam Franz Kollár (1718-1783) who used and defined it in his "Historiae ivrisqve pvblici Regni Vngariae amoenitates" published in Vienna in 1783. as: “the science of nations and peoples, or, that study of learned men in which they inquire into the origins, languages, customs, and institutions of various nations, and finally into the fatherland and ancient seats, in order to be able better to judge the nations and peoples in their own times.”
