In what year or era was 'The Good Morrow' by John Donne written?
The above post gives you great historical information. You might also consider the "literary era" with which John Donne is associated. He is usually characterized as a Metaphysical Poet and is sometimes even credited with developing this style of poetry. The poems are marked by extremely clever and intellectual metaphors called conceits. In this poem, he is comparing he and his love to hemispheres of earth and stating that they should be indivisible.
He is suggesting that they are they perfect balance of the elements, and therefore are a perfect love. He also suggests that their relationship represents the whole world. He is certainly making a lot of grand statements!
John Donne was a Jacobean poet.
As Shakespeare was an Elizabethan playwright and poet, Donne was a famous metaphysical poet of the Jacobean era. The term metaphysical was later defined by Dr. Samuel Johnson. The Jacobean era refers to the period during King James' reign (1603-1625). This literary period succeeds the Elizabethan era. The age gives us some famous playwrights like Ben Jonson, John Webster, and legendary poets like Donne.
It should be added here, the English name James is a "transliteration of the Greek name Jacobos, which in turn is a transliteration of the Hebrew name Jacob" (http://www.abarim-publications.com/Meaning/Jacob.html). That's why the period during King James' reign is called Jacobean era.
The poem, you can find, was first published in 1633.
