The good lady Opinion sits perched in a tree, wearing the weighty towers of the town as her hat, which blinds her eyes. On one of her hands a chameleon sits, doubtless changing its spots to accommodate the surroundings. Held in her other hand is a wand used to shake the tree's branches, from which leaves fall: leaves of books and papers, which offer not knowledge but libel and foolishness, which ''in everie streete, on everie stall you find.'' Such is the cynical vision of the news business put forward by Henry Peacham in 1641 London, as journalism, in its earliest forms, was becoming a major force during some of the most tumultuous decades in England's history: no wisdom, he finds, just much posturing and gossip.
