Archaeology
It "is the study of human activity in the past, primarily through the recovery and analysis of the material culture and environmental data that they have left behind, which includes artifacts, architecture, biofacts and cultural landscapes (the archaeological record)."

Mythology
"Cultural artifact is a term used in the social sciences, particularly anthropology, ethnology, and sociology ... for anything created by humans which gives information about the culture of its creator and users. Usage of this term encompasses the type of archaeological artifact which is recovered at archaeological sites; however, current objects of modern or near-modern society are also cultural artifacts. For example, in an anthropological context, a 17th-century lathe, a piece of faience, or a television each provide a wealth of information about the time in which they were manufactured and used. Cultural artifacts can provide knowledge about technological processes, economy and social makeup, and a host of other subjects."
