the several Artifices which are put in Practice by the Poets to fill the Minds of
an
Audience with Terror, the first Place is due to Thunder and Lightning, which are often made use of at the Descending of a God, or the Rising of a Ghost, at the Vanishing of a Devil, or at the Death of a Tyrant. I have known a Bell introduced into several Tragedies with good Effect; and have seen the whole Assembly in a very great Alarm all the while it has been ringing. But there is nothing which delights and terrifies our
English
Theatre so much as a Ghost, especially when he appears in a bloody Shirt. A Spectre has very often saved a Play, though he has done nothing but stalked across the Stage, or rose through a Cleft of it, and sunk again without speaking one Word. There may be a proper Season for these several Terrors; and when they only come in as Aids and Assistances to the Poet, they are not only to be excused, but to be applauded.
