Because of their significance in everyday life in ancient Egypt, this works provides a specific lexicography of terms with textual and bibliographical references to cattle, sheep and goats. In ancient Egypt there were many words to indicate cattle, sheep and goats, and the same term can often represent different meanings. These variations depend on the genre and the dating of the texts and where the term appears. To classify and analyse the different writings and the etymology of the words for these domesticated animals, the author of this research examines Egyptian documents from the Old Kingdom to the Greek-Roman Period and then considers the specific and derived meanings. The work concludes with a general synthesis of current studies on cattle, sheep and goats.
