The Baroque style of art, music, and literature is the most defining or memorable style of the Seventeenth Century, when the Reformation and Counter-Reformation were most intense, but its use or application to art of the time is not automatic or universal.
The Baroque expressed itself especially in Catholic culture and art. Protestant countries, as in Baroque music by German composers like Bach and Telemann.
Some Baroque qualities appear in Puritan writers. The American Puritan poets Anne Bradstreet (1612-72) and Edward Taylor (1642-1729) and the English nonconformist poet-minister George Herbert all used the Baroque poetic stylistic feature known as "the conceit" or extended metaphor. The "conceit" (or "concept") resembles Baroque aesthetics on account of its extravagance and occasional deformity through the stress of extension.
