Bacon's works are seen as developing the scientific method and remained highly influential through the Scientific Revolution. Robert Filmer wrote on the Divine Right of Kings. All the 16th century Tudor monarchs were highly educated, as was much of the nobility, and Italian literature had a considerable following, providing the sources for many of Shakespeare's plays. English thought advanced towards modern science with the Baconian Method. The language of the Book of Common Prayer, first published in 1549, and at the end of the period the Bible had enduring and profound impacts on the English consciousness. Visual arts England was slow to produce visual arts in Renaissance styles, and the artists of the Tudor court were mainly imported foreigners until after the end of the Renaissance; Hans Holbein was the outstanding figure.

The portraiture of Elizabeth I was carefully controlled and developed into an elaborate and wholly un-realist iconic style, that has succeeded in creating enduring images. The many portraits drove the evolution of English royal portraits in the Early Modern period. Even the earliest portraits of Elizabeth I contain symbolic objects such as roses and prayer books that would have carried meaning to viewers of her day. Later portraits of Elizabeth layer the iconography of empire—globes, crowns, swords and columns—and representations of virginity and purity—such as moons and pearls—with classical allusions to present a complex "story" that conveyed to Elizabethan era viewers the majesty and
