At the same time the seventeenth-century scientific movement, heralded pre-eminently by Francis Bacon, had the effect of establishing English finally as an adequate medium of technical writing in place of Latin. It also led to the cultivation of a plain style of writing, without the use of the devices of rhetoric. Bacon, who wrote in both English and Latin, himself criticized the valuing of style above matter. His followers carried the attack much further. The Royal Society, according to its historian, Bishop Thomas Sprat, was to be praised for correcting stylistic excesses in writing.
