Tirso de Molina
"The Opportunity" was licensed for performance by Sir Henry Herbert, the Master of the Revels, on 29 November 1634. It was acted by Shirley's regular company, Queen Henrietta's Men, at the Cockpit Theatre. The 1640 quarto was dedicated by Shirley to a personal friend, Capt. Richard Owen. Shirley relied on "El Castigo del Penséque" by Tirso de Molina as his source for the plot of his play.
