I was moved to write this play by many reasons: Amongst others, the commands of some persons of honour, for whom I have a most particular respect, were daily sounding in my ears, that it would be of good example to undertake a poem of this nature. Neither were my own inclinations wanting to second their desires. I considered that pleasure was not the only end of poesy; and that even the instructions of morality were not so wholly the business of a poet, as that the precepts and examples of piety were to be omitted. For, to leave that employment altogether to the clergy, were to forget that religion was first taught in verse, which the laziness, or dulness, of succeeding priesthood, turned afterwards into prose; and it were also to grant (which I never shall) that representations of this kind may not as well be conducing to holiness, as to good manners. Yet far be it from me to compare the use of dramatick poesy with that of divinity: I only maintain, against the enemies of the stage, that patterns of piety, decently represented, and equally removed from the extremes of superstition and profaneness, may be of excellent use to second the precepts of our religion. By the harmony of words we elevate the mind to a sense of devotion, as our solemn musick, which is inarticulate poesy, does in churches; and by the lively images of piety, adorned by action, through the senses allure the soul; which while it is charmed in a silent joy of what it sees and hears, is struck, at the same time, with a secret veneration of things celestial: and is wound up insensibly into the practice of that which it admires. Now if, instead of this, we sometimes see on our theatres the examples of vice rewarded, or, at least, unpunished; yet it ought not to be an argument against the art, any more than the extravagances and impieties of the pulpit, in the late times of rebellion, can be against the office and dignity of the clergy. But many times it happens, that poets are wrongfully accused; as it is my own case in this very play; where I am charged by some ignorant or malicious persons, with no less crimes than profaneness and irreligion.
