Pillory, an obsolete instrument of punishment for centuries in use all over Europe, consisted of a platform, an upright pole, and at a convenient height cross-boards with holes, in which the culprit's neck and wrists were placed and fastened; so fixed he was exposed in some public place to the insults and noxious missiles of the mob. Formerly in England the penalty of forgery, perjury, &c., it became after the Commonwealth a favourite punishment for seditious libellers. It was last inflicted in London in 1830, and was abolished by law in 1837.
