A symbol of good luck and health. A cricket on the hearth has been a sign of household luck for millennia and in many cultures. Crickets were widely considered to bring good fortune as well as a kind of companionship. Representations of a cricket have long been included as a fireplace decoration. The expression “to find a cricket on the hearth is the luckiest thing of all” comes from Charles Dickens's novella, Cricket on the Hearth.
