This noble unself-consciousness is what we find in all truly great men, in the founders of the arts. I picture the great Poussin, in his retreat, delighting in the study of the human heart.. ..I picture Raphael in the arms of his mistress, turning from La Fornarina to paint his Saint Cecilia.. ..I am only too well aware that I am far not only from their divine spirit, but even from their modest simplicity...

In the midst of the activities that distract me [shooting partridges in the woods], when I remember a few lines of poetry, when I recall some sublime painting, my spirit is roused to indignation and spurns the vain sustenance of the common herd. And in the same way, when I think of those I love, my soul clings eagerly to the elusive trace of these cherished ideas. Yes, I am sure of it, great friendship is like great genius, and the remembrance of a great and enduring friendship is like that of great works of genius... What a life would be that of two great poets who loved each other as we do! That would be too great for human kind.
