The metaphysical poets were a loose group of British lyric poets of the 17th century, who shared an interest in metaphysical concerns and a common way of investigating them, and whose work was characterised by inventiveness of metaphor (these involved comparisons being known as metaphysical conceits). These poets were not formally affiliated; most of them did not even know or read each other. Their poetry was influenced greatly by the changing times, new sciences and the new found debauched scene of the 17th century.
