Dead White Poets Society by WinchellV

Question 11

"And did those feet in ancient time / Walk upon England's mountains green: / And was the holy Lamb of God, / On England's pleasant pastures seen!" So begins an anthem used in many Anglican churches on St. George's day, among other occasions. Sir Hubert Parry wrote the tune in 1916. What visionary English POET wrote the words?

William Blake
