brocard; Brocard’s circle and ellipse. Brocard was the French name for Burchard, an 11th-century bishop of Worms. Bishop Brocard published a collection of canons, Regulae Ecclesiasti- cae, celebrated for its short, sententious sentences, and a brocard soon came to mean both a brief maxim or proverb in philoso- phy or law and a pointed jibe or biting speech. Brocard’s circle and Brocard’s ellipse are mathematical terms named for French mathematician Henri Brocard (1845–1922). |
