All these early works were painted with great attention to detail, often concentrating on the beauty and complexity of the natural world. This style was promoted by the critic John Ruskin. However, Ruskin’s wife Effie Gray left him for Millais. After his marriage to Effie, Millais began to paint in a broader style, which Ruskin attacked. Works such as The Eve of St. Agnes and The Somnambulist show the influence of Whistler. Others demonstrate Millais's reverence for Velázquez and Rembrandt. Millais achieved great popularity with his paintings of children, notably Bubbles and Cherry Ripe. Larger works, such as The Boyhood of Raleigh and The North-West Passage, often portrayed episodes in Britain's imperial history.
Millais was also very successful as a book illustrator, notably for the works of Anthony Trollope.
