"The idea that graves should always be 6 feet deep has been around for a long time. There is no agreement about where this idea came from. For some it comes from London in 1665, where the Lord Mayor ordered that all "graves shall be at least 6-foot deep" under the presumption that doing so would prevent the spread of the Black Death."
