Etymology of "Parse"

Surely *to parse* is to take by itself each *pars*, or part of speech. The word does not seem to have been known in 1611 when Brinsley published his *Posing of the Parts: or, a most plain and easie Way of examining the Accidence and Grammar*. This work appears to have been very popular, as I have by me the *twelfth* edition, London, 1669. In 1612, the same author issued his *Ludus Literarius: or the Grammar Schoole*. Both these works interest me in him. Can any of your readers communicate any particulars of his history?
