Though thus driven out of his favourite style of the rhymed tragedy, he was not driven from the stage. Bound by his agreement with the King's Company to furnish three plays a-year, he continued to make dramatic writing his chief occupation; and almost his sole productions during the first ten years of his laureateship were ten plays. Three of these were prose-comedies; one, a tragi-comedy, in blank verse and prose; one, an opera in rhyme; five, tragedies in blank verse; and one, the rhymed tragedy above referred to. It will be observed that this was at the rate of only one play a-year, whereas, by his engagement, he was to furnish three. The fact was that the company were very indulgent to him, and let him have his full share of the receipts, averaging 300_l._ a-year, in return for but a third of the stipulated work. Notwithstanding this, we find them complaining, in 1679, that Dryden had behaved unhandsomely to them in carrying one of his plays to the other theatre, and so injuring their interests. As, from that year, none of Dryden's plays were produced at the King's Theatre, but all at the Duke's, till 1682, when the two companies were united, it is probable that in that year the bargain made with Killigrew terminated. It deserves notice, by the way, that the so-called "opera" was one entitled _The State of Innocence; or, The Fall of Man_, founded on Milton's _Paradise Lost_, and brought out in 1674-5, immediately after Milton's death. That this was an equivocal compliment to Milton's memory Dryden himself lived to acknowledge. He confessed to Dennis, twenty years afterwards, that at the time when he wrote that opera "he knew not half the extent of Milton's excellence." A striking proof of Dryden's veneration for Milton, when we consider how high his admiration of Milton had been even while Milton was alive! Of these dramatic productions of Dryden during the first ten years of his laureateship some were very carefully written. Thus _Marriage à-la-mode_, performed in 1672, is esteemed one of his best comedies; and of the rhymed tragedy, _Aurung-Zebe_, performed in 1675, he himself says in the Prologue-- "What verse can do he has performed in this, Which he presumes the most correct of his."
