Jacobethan

Jacobethan is the style designation coined in 1933 by John Betjeman to describe the mixed national Renaissance revival style that was made popular in England from the late 1820s, which derived most of its inspiration and its repertory from the English Renaissance (1550–1625), with elements of Elizabethan and Jacobean. The "Jacobethan" architectural style is also called "Jacobean Revival". Betjeman's original definition of the style is as follows:

The style in which the Gothic predominates may be called, inaccurately enough, Elizabethan, and the style in which the classical predominates over the Gothic, equally inaccurately, may be called Jacobean. To save the time of those who do not wish to distinguish between these periods of architectural uncertainty, I will henceforward use the term "Jacobethan".

The term caught on with art historians. Timothy Mowl asserts in The Elizabethan and Jacobean Style (2001) that the 'Jacobethan' style represents the last outpouring of an authentically native genius that was stifled by slavish adherence to European baroque taste.
