Henry Constable (1562–1613) was a notable English poet of the Elizabethan era, primarily recognized for his contributions to the sonnet form. He is best known for his sonnet sequence Diana, which was first published in 1592 and became a popular example of the Petrarchan tradition in England. A devout Catholic, his religious beliefs heavily influenced his later works and led to a life of exile from Protestant England. Constable's poetry is celebrated for its elegant style, refined language, and skillful blending of secular and religious themes, securing his place among the important minor poets of his time.
