This business of street-oratory, while it amuses the populace, and keeps them from less innocent and more expensive pastimes, gives them at the same time some general ideas of history. Street-orators, therefore, are a more useful set of men than another class, of which there are numbers at Rome, who entertain companies with extemporaneous verses on any given subject. The last are called Improuvisatoris; and some people admire these performances greatly. For my own part, I am too poor a judge of the Italian language either to admire or condemn them; but, from the nature of the thing, I should imagine they are but indifferent. It is said, that the Italian is peculiarly calculated for poetry, and that verses may be made with more facility in this than in any other language. It may be more easy to find smooth lines, and make them terminate in rhime in Italian, than in any language; but to compose verses with all the qualities essential to good poetry, I imagine leisure and long reflection are requisite. Indeed I understand, from those who are judges, that those extempore compositions of the Improuvisatori are in general but mean productions, consisting of a few fulsome compliments to the company, and some common-place observations, put into rhime, on the subject proposed. There is, however, a lady of an amiable character, Signora Corilla, whose extempore productions, which she repeats in the most graceful manner, are admired by people of real taste. While we were at Rome, this lady made an appearance one evening, at the assembly of the Arcadi, which charmed a very numerous company; and of which our friend Mr. R—y has given me such an account, as makes me regret that I was not present. After much entreaty, a subject being given, she began, accompanied by two violins, and sung her unpremeditated strains with great variety of thought and elegance of language. The whole of her performance lasted above an hour, with three or four pauses, of about five minutes each, which seemed necessary, more that she might recover her strength and voice, than for recollection; for that gentleman said, that nothing could have more the air of inspiration, or what we are told of the Pythian Prophetess. At her first setting out, her manner was sedate, or rather cold; but gradually becoming animated, her voice rose, her eyes sparkled, and the rapidity and beauty of her expressions and ideas seemed supernatural. She at last called on another member of the society to sing alternately with her, which he complied with; but Mr. R——y thought, though they were _Arcades ambo_, they were by no means _cantare pares_.
