Minamoto no Tsunenobu was an 11th-century courtier and talented poet. One autumn night, while viewing the moon from his home in Rokujo, he heard a sound like cloth being beaten with a mallet. He recited a poem: “I listen to the sound of cloth being pounded/ as the moon shines serenely/ and believe that there is someone else/ who has not yet gone to sleep.” Suddenly, a demonic spirit appeared and recited a Chinese poem similar to Tsunenobu’s. Though the demon incited great terror within the household, he did them no harm. In this work, Yoshitoshi shows only the beastly leg of the demon, focusing instead on the human reaction to the monster.
