Biblical canonA biblical canon is a set of texts (also called "books") which a particular Jewish or Christian religious community regards as part of the Bible. The English word canon comes from the Greek κανών kanōn, meaning "rule" or "measuring stick". The use of the word "canon" to refer to a set of religious scriptures was first used by David Ruhnken, in the 18th century. Various biblical canons have developed through debate and agreement on the part of the religious authorities of their respective faiths and denominations.

It survived the fall of the Western Roman Empire in the 5th century AD and continued to exist until the fall of Constantinople to the Ottoman Empire in 1453. During most of its existence, the empire remained the most powerful economic, cultural, and military force in the Mediterranean world.
