Did You Know?

Aside from historical references to siege warfare, and occasional contemporary references to fireworks, petard is almost always encountered in variations of the phrase "hoist with one's own petard," meaning "victimized or hurt by one's own scheme." The phrase comes from William Shakespeare's Hamlet: "For 'tis the sport to have the enginer / Hoist with his own petar." Hoist in this case is the past participle of the verb hoise, meaning "to lift or raise," and petar(d) refers to an explosive device used in siege warfare. Hamlet uses the example of the engineer (the person who sets the explosive device) being blown into the air by his own device as a metaphor for those who schemed against him being undone by their own schemes. The phrase has endured, even if its literal meaning has largely been forgotten.


Examples

"The metal walls of the narrow corridor would scatter ricochets and shrapnel in every direction, and any intact panels of reflex armor would ignite grenades and petards in counterfire…." — John C. Wright, The Judge of Ages, 2014

"I ran back and seized a tin box which had been filled with candles. It was about the size of my busby—large enough to hold several pounds of powder. Duroc filled it while I cut off the end of a candle. When we had finished, it would have puzzled a colonel of engineers to make a better petard." — Sir Arthur Conan Doyle, The Exploits of Brigadier Gerard, 1896
