His taste, which was not limited to the circle of his own art, evinced itself enthusiastically in favor of pictures; and he lived in habits of intimacy with Carlo Cignani and Carlo Maratti. It seems that he had accumulated a sum equal to £6000. The account that is given of his having bequeathed the whole of this amount, besides a valuable collection of pictures, to his patron, Cardinal Ottoboni, has been observed to savour more of vanity than of true generosity; and, indeed, the Cardinal evinced the most considerate appreciation of the bequest, by reserving only the pictures, and distributing the remainder of Corelli’s effects among his indigent relations. In regard to the peculiar merits of Corelli’s productions, it may be briefly said, that his Solos (or _Opera Quinta_), as a classical book for forming the hand of a young practitioner on the violin, has ever been regarded, by the most eminent masters of the instrument, as a truly valuable work; and it is said, of this elaborate work (on which all good systems for the instrument have since been founded), that it cost him three years to revise and correct it. Indeed, all his compositions are said to have been written with great deliberation, to have been corrected by him at many different times, and to have been submitted to the inspection of the most skilful musicians of his day. Of his Solos, the second, third, fifth, and sixth are admirable; as are the ninth, tenth, and, for the elegant sweetness of its second movement, the eleventh. The ninth is probably the most perfect, as a whole; and the Solos, generally, seem to have been drawn from the author’s native resources, more extensively than any of his other productions. The most emphatic evidence of the value of these Solos lies in the fact of their adoption by the highest instructors. Tartini formed all his scholars on them; and it was the declaration of Giardini, that, of any two pupils of equal age and abilities, if the one were to begin his studies by Corelli, and the other by Geminiani, or any other eminent master whatever, the first would become the better performer. Let it be observed, however, that it is not from Corelli, that the niceties and dexterities of _bowing_, which characterize the modern state of the art, are derived. The qualities he is capable of imparting are tone and time: or, in other words, he teaches the full extraction of sound, and the utmost steadiness of hand.
