Varium et mutabile semper femina is the sharpest satire, in the fewest words, that ever was made on womankind; for both the adjectives are neuter, and animal must be understood, to make them grammar. Virgil does well to put those words into the mouth of Mercury. If a god had not spoken them, neither durst he have written them, nor I translated them.
