Macarius of Egypt was a Christian monk and grazer hermit. He is also known as Macarius the Elder or Macarius the Great.

Christian monasticism is the devotional practice of Christians who live ascetic and typically cloistered lives that are dedicated to Christian worship. It began to develop early in the history of the Christian Church, modeled upon scriptural examples and ideals, including those in the Old Testament. It has come to be regulated by religious rules and, in modern times, the Canon law of the respective Christian denominations that have forms of monastic living. Those living the monastic life are known by the generic terms monks (men) and nuns (women). The word monk originated from the Greek μοναχός, itself from μόνος meaning 'alone'.
