The first published English grammar was a "Pamphlet for Grammar" of 1586, written by William Bullokar with the stated goal of demonstrating that English was just as rule-based as Latin. Bullokar's grammar was faithfully modeled on William Lily's Latin grammar, "Rudimenta Grammatices" (1534), used in English schools at that time, having been "prescribed" for them in 1542 by Henry VIII. Bullokar wrote his grammar in English and used a "reformed spelling system" of his own invention; but much English grammar, for much of the century after Bullokar's effort, was written in Latin, especially by authors who were aiming to be scholarly. John Wallis's "Grammatica Linguae Anglicanae" (1685) was the last English grammar written in Latin.
