The first _description_ of an Opera which I have met with is in the eleventh number of the Theatre, for November 18, 1758. As the writer appears to have entered into the subject with more than usual spirit, its insertion may possibly prove acceptable to the reader; but he will immediately discover that even our Theatres for pantomime now rival the antient Opera. "King's Theatre. On Saturday the 18th instant was performed a new Opera called _Attalo_, with new decorations and dances. I have already thrown out a few loose hints with regard to the abovementioned performance; and as in this place I propose speaking of it a little more at large, I shall begin with observing, that an Opera has in one particular a manifest advantage over almost every theatrical entertainment, by admitting of that kind of shew and decoration, which if not absolutely rejected by the other daughters of the Drama, is at least, generally speaking, forced upon them: that is to say, though we sometimes see triumphs and processions in a few of our tragedies and comedies, yet the best judges have always looked on them as childish and ridiculous: whereas, the only design of an Opera being to delight, that gay finery which looks so unbecoming and out of character upon her two elder sisters, is a necessary part of her dress; and as nobody understands the method of placing those ornaments better than Mr. Vaneschi, so in the present case I think he has taken all the care imaginable to set off _Attalo_ to the best advantage. "But a dry and circumstantial description of these matters would not only fall very short of what is meant to give an idea of, but also be tedious to the readers: for this reason therefore I shall hardly attempt to do any thing more in the present essay than to assure them that the finest scenes, the finest pantomime hitherto invented, even by that father of pantomimes himself, the manager of Covent-garden playhouse, are considerably inferior to those in the Opera of _Attalo_; but particularly, in the first act, where Semiramis enters in a triumphal car, supported by Medean and Bactrian slaves, and surrounded by a number of Assyrian soldiers who carry the spoils and trophies of an enemy which she is supposed lately to have conquered, we are presented with the scene of a square; not a dead piece of painted canvass, but one in which the prospective is executed in so masterly a manner, that one would almost swear it was something more than a mere _deceptio visûs_; to which, by the way, a pedestrian statue, which is elevated in the centre of the buildings, does not a little contribute.
