Ivan the Terrible and His Son Ivan on 16 November 1581, by Ilya Repin (1883-1885)
Ilya Repin: I painted in tears, I was tortured, I tormented myself, I corrected again and again what I had painted, I hid it, in a sickly disappointment, no longer believing in my strength, I erased what I had painted. I had already erased, and I was attacking the canvas again. Every minute was terrible to me. I was disappointed with this painting, I hid it. And she made the same impression on my friends. But something pushed me towards her, and again I was working on it.
