nights was Southern; and the first that had three was Rowe. There were, however, in those days, arts of improving a poet's profit, which Dryden forbore to practise; and a play therefore seldom produced him more than a hundred pounds, by the accumulated gain of the third night, the dedication, and the copy.
Almost every piece had a dedication, written with such elegance and luxuriance of praise, as neither haughtiness nor avarice could be imagined able to resist. But he seems to have made flattery too cheap. That praise is worth nothing of which the price is known.
To increase the value of his copies, he often accompanied his work with a preface of criticism; a kind of learning then almost new in the English language, and which he, who had considered with great accuracy the principles of writing, was able to distribute copiously, as occasions arose. By these dissertations the public judgement must have been much improved; and Swift, who conversed with Dryden, relates that he regretted the success of his own instructions, and found his readers made suddenly too skilful to be easily satisfied.
