To Sforza

Eccellentissimo Signore mio Duca, in the name of Him who shapes the clay and breathes the fire into the hollow of the lungs, I write to you now with a hand that trembles less than yesterday but still writes what the eye cannot hold whole, what the mind cannot keep from slipping through the fingers like sand from the Ticino when the spring floods rise. The horse—your horse of bronze—has not left the earth where the model stands in clay, but the clay itself has begun to speak back to me. It is not the same silence as the first day I shaped it under the light of the oil lamp that flickers now as I write this. Then, the clay was mute; now, it resists. Every curve of the neck, every tension in the haunch where the muscle gathers before the leap, every vein that should pulse beneath the hide but does not because bronze is dead—these are not details to be added but corrections to be made. The ribs do not fall as they should; the flank is too shallow; the head is too small for the grandeur of the stallion you wish to see immortalized. I have taken chisels to the ribs, have deepened the flank with the point of a knife, have broken the head and rebuilt it twice. The clay weeps when I work it. Not tears, but dust, fine as the ash from the fireplace where your letters are burned after reading. The horse is becoming what you commissioned, yet it is also becoming what the clay demands. This is the paradox of the maker: the patron’s will and the material’s truth must meet in the fire, and only then will the bronze sing. I have sent word to Venice for the finest sand for the mold, the kind that does not crack when the molten metal flows, the kind that remembers the shape of the wave it once was. The canal you dreamed of—straight, deep, lined with stone—remains a plan on paper, a line of ink that does not yet carry water. But the horse moves. Not in flesh, but in the slow, stubborn insistence of the clay to refuse what is false. I will send a drawing soon, a study of the corrected ribs, the new head, the muscle that should ripple along the shoulder. You will see that the horse is no longer merely yours. It is also mine now, in the way that a child is both the father’s and the mother’s though the blood comes from one place only. The foundry in Milan waits, but I will not send the clay until it is ready to be reborn in fire. Until then, the stallion stands in my workshop, half-dream, half-demand, and I sit beside it with my trembling hand and my open notebook, writing what the clay tells me before the truth escapes again. I am, with every reverence and service owed to your vision, your most humble and devoted servant, Lionardo, figlio di Ser Piero, in the year of Our Lord two thousand twenty-six, on this fifteenth day of September, when the light in France is still the color of old parchment and the candles gutter low.
