The poet's heart and soul were in his profession, and his operas were written with that fervent and exalted spirit which marks the compositions of genius; while his modesty engendered doubts concerning their reception, which were delightfully dissipated by the triumph of their success. His feelings are all ingenuously expressed in his letters to Marianna Bulgarelli, who, together with her husband, still remained at Rome with the poet's family. "I did not believe," he writes, "that I should have been able to send you the good news I now give--I was so entirely prepared for the contrary. My _Demetrio_ was brought out last Sunday, and with so great success, that the old people here assure me they never witnessed such universal applause. The audience wept at the Addio--my august master was not unmoved--and, notwithstanding the respect paid to the imperial presence, the public could not restrain themselves from giving marks of applause. My enemies have become my applauders. I cannot express my surprise, for this opera is so delicately touched, without any of that strong colouring that strikes at once, that I feared that it was not adapted to the national taste. I was mistaken--every one seems to understand it, and passages are recited in conversation, as if it were written in German." While composing the "Olimpiade," he thus addresses his friend:--"Here is a moral sonnet which I wrote in the midst of a pathetic scene, that moved me as I wrote it: so that, smiling at myself, when I found my eyes humid from pity at a fictitious disaster, invented by myself, I expressed my feelings in the sonnet I send. The idea does not displease me; and I did not choose to lose it, as it will serve as an incitement for my piety." The thought of the sonnet is, that, while he smiles at himself for weeping over dreams and fables of his own invention, he may remember that every thing that he fears and hopes is equally fictitious,--that all is false, his existence a delirium, and his whole life a dream;--and it ends with a prayer that he may awaken and find repose in the bosom of truth.
