But swept on the full current of desire Would steer our course with unimpeded hands, Watching the pleasure in each other's eyes. Ah well, 'tis vain to talk! Two-thirds of life Till now I've spent in spotless purity— Affection's been retarded by desire As has my work; my dreams have far excelled The beauty God moulds into human shape. The sweet perfection of the womankind Who haunt my brain, has held me back from love. This . . . this was so till Mona Lisa came. Four years I've painted when it was her day, A day of mist, of mingled rain and sun; Four years before me silently she's sat And smiled to see me strive to catch her smile In liquid paint, with canvas and with brush, So that her eyes, searching, inscrutable, May question her sons' sons when she is dust. I only just begin to know her face.
