This is a long poem by Edward Young published in nine parts (or "nights") between 1742 and 1745. The poem is written in blank verse. It describes the poet's musings on death over a series of nine "nights" in which he ponders the loss of his wife and friends, and laments human frailties. The best-known line in the poem is the adage "procrastination is the thief of time", which is part of a passage in which the poet discusses how quickly life and opportunities can slip away.
