This is a copy of a ca. 1768 edition of Isaac Bickerstaff libretto for the two-act English comic opera "The Paddlock" by Charles Dibdin. The plot is an adaptation of Miguel de Cervantes's "El celoso extremeño" (translated as, The Jealous Estremaduran). The t.p. features a vignette signed by IJ Taylor [possibly by the London engraver Isaac Taylor (1730-1807)] with four infants. The one at the center is holding several keys and is playing horse riding with a walking stick that has a padlock attached to it. In the story, Don Diego, a rich old man, hopes to marry the young Leonora and locks her inside his house using a large padlock on the front door. After bribing the servants, the younger suitor, Leander, climbs over the garden wall to court Leonora. Don Diego returns unexpectedly and catches the lovers, but allows the young couple to wed acknowledging that he is too old for Leonora.
