All For Love, a full-fledged heroic play written by John Dryden, has ever enjoyed literary merit and public acclaim since its first performance in 1677.

More crucially, all for Love exerted a tremendous influence on the upcoming genre, and became a prototype to Sentimental Tragedy of the 18th Century.
