Browning was one of the greatest Victorian poets admired by few but not widely popular. His work was enormously varied, including poems on art, music, history, and contemporary life. He could write short lyrics or long dramatic monologues with equal skill. As a poet, he had a threefold appeal - as a psychological poet, a passionate lover of love, and a believer in optimism. Browning was most interested in studying the human mind and soul, focusing on internal mental life rather than outward actions. He provided insightful psychological portraits of many different types of characters from various times and places. A core theme in his work was his philosophy that love is what gives life meaning.
