Prior to this, his work often faced indifference or unfavorable reviews, and he struggled to attain the level of fame enjoyed by his contemporaries, such as Alfred, Lord Tennyson. After 1864, however, his reputation grew rapidly, and the subsequent publication of his major work, The Ring and the Book (1868–69), firmly established him as one of the most significant literary figures of the Victorian era.132
