The English name of Turkey (from Medieval Latin ''Turchia''/''Turquia'') means "land of the Turks". Middle English usage of ''Turkye'' is evidenced in an early work by Chaucer called ''The Book of the Duchess'' (c. 1369). The phrase ''land of Torke'' is used in the 15th-century Digby Mysteries. Later usages can be found in the Dunbar poems, the 16th century ''Manipulus Vocabulorum'' (''Turkie'') and Francis Bacon's ''Sylva Sylvarum'' (''Turky''). The modern spelling ''Turkey'' dates back to at least 1719.
