Tetrachordon

Tetrachordon (from the Greek τετράχορδον "four stringed") was published by the English poet and polemicist John Milton with his Colasterion on 4 March 1645. The title symbolizes Milton's attempt to connect four passages of Biblical scripture to rationalize the legalization of divorce.

Milton connects four Scriptural passages (Genesis 1:27–28, Deuteronomy 24:1, Matthew 5:31–32 and 19:2–9, and I Corinthians 7:10-16) in order to argue that Scripture supports the legalization of divorce. In addition to this argument, the work is targeted at Herbert Palmer, who attacked Milton's The Doctrine and Discipline in a sermon to Parliament, and pamphlets published in support of Palmer's position.
