An eponym is a person, a place, or a thing after whom or which someone or something is, or is believed to be, named. The adjectives which are derived from the word eponym include eponymous and eponymic. Usage of the word The term eponym functions in multiple related ways, all based on an explicit relationship between two named things. A person, place, or thing named after a particular person share an eponymous relationship. In this way, Elizabeth I of England is the eponym of the Elizabethan era. When Henry Ford is referred to as "the eponymous founder of the Ford Motor Company", his surname "Ford" serves as the eponym. The term also refers to the title character of a fictional work (such as Rocky Balboa of the Rocky film series), as well as to self-titled works named after their creators (such as the album The Doors by the band the Doors). Walt Disney created the eponymous Walt Disney Company, with his name similarly extended to theme parks such as Walt Disney World. Medical eponymous terms are often called medical eponyms although that usage is deprecable. History Periods have often been named after a ruler or other influential figure: One of the first recorded cases of eponymy occurred in the second millennium BC, when the Assyrians named each year after a high official (limmu). In ancient Greece, the eponymous archon was the highest magistrate in classical Athens. Eponymous archons served a term of one year which took the name of that particular archon (e.g., 594 BC was named after Solon). Later historians provided yet another case of eponymy by referring to the period of fifth-century Athens as The Age of Pericles after its most influential statesman Pericles. In Ptolemaic Egypt, the head priest of the Cult of Alexander and the Ptolemies was the eponymous priest after whom years were named. The Hebrew Bible explains the origins of peoples through individuals who bear their name. Jacob is renamed "Israel" (Gen 35:9) and his sons (or grandsons) name the original 12 tribes of Israel, while Edomites (Gen. 25:30), Moabites and Ammonites (Gen. 19:30-38), Canaanites (Gen. 9:20-27) and other tribes (the Kenites named after Cain (Cain's life is detailed in Gen. 4:1-16)) are said to be named after other primal ancestors bearing their name. In most cases, the experiences and behavior of the ancestor is meant to indicate the characteristics of the people who
