Nicholas Hilliard was an English goldsmith and limner best known for his portrait miniatures of members of the courts of Elizabeth I and James I of England. He mostly painted small oval miniatures, but also some larger cabinet miniatures, up to about 10 inches tall, and at least two famous half-length panel portraits of Elizabeth. He enjoyed continuing success as an artist, and continuing financial troubles, for forty-five years. His paintings still exemplify the visual image of Elizabethan England, very different from that of most of Europe in the late sixteenth century. Technically he was very conservative by European standards, but his paintings are superbly executed and have a freshness and charm that has ensured his continuing reputation as "the central artistic figure of the Elizabethan age, the only English painter whose work reflects, in its delicate microcosm, the world of Shakespeare's earlier plays."

A portrait miniature is a miniature portrait painting, usually executed in gouache, watercolor, or enamel. Portrait miniatures developed out of the techniques of the miniatures in illuminated manuscripts, and were popular among 16th-century elites, mainly in England and France, and spread across the rest of Europe from the middle of the 18th century, remaining highly popular until the development of daguerreotypes and photography in the mid-19th century. They were usually intimate gifts given within the family, or by hopeful males in courtship, but some rulers, such as James I of England, gave large numbers as diplomatic or political gifts. They were especially likely to be painted when a family member was going to be absent for significant periods, whether a husband or son going to war or emigrating, or a daughter getting married.
