This demoness is not to be connected with the Italian Mania, probably of Etruscan origin, with which nurses frightened children. This Mania, from an old word manus signifying ‘good,’ was, from the relation of her name to Manes, supposed to be mother of the Lares, whose revisitations of the earth were generally of ill omen. According to an oracle which said heads should be offered for the sake of heads, children were sacrificed to this household fiend up to the time of Junius Brutus, who substituted poppy-heads.
