Typically, 11th- and 12th-century founders had endowed monastic houses with both 'temporal' income in the form of revenues from landed estates, and 'spiritual' income in the form of tithes appropriated from parish churches under the founder's patronage. In consequence of this, religious houses in the 16th century controlled appointment to about two-fifths of all parish benefices in England, disposed of about half of all ecclesiastical income, and owned around a quarter of the nation's landed wealth. An English medieval proverb said that if the abbot of Glastonbury married the abbess of Shaftesbury, their heir would have more land than the king of England.
