This is John Donne (1572-1631). He also wrote erotic poems (yes!) but more of it later.
He was born in a big island, Great Britain.

"No man is an island. entire of itself; every man is a piece of the continent, a part of the main; if a clod be washed away by the sea, Europe is the less, as well as if a promontory were, as well as if a manor of thy friend's or of thine own were; any man's death diminishes me, because I am involved in mankind, and therefore never send to know for whom the bell tolls; it tolls for thee."
