"In Eastern Christianity, the most widely used Christogram is a four-letter abbreviation, ΙϹ ΧϹ—a traditional abbreviation of the Greek words for "Jesus Christ". On icons, this Christogram may be split: "ΙϹ" on the left of the image and "ΧϹ" on the right. It is sometimes rendered as "ΙϹ ΧϹ ΝΙΚΑ" meaning "Jesus Christ Conquers.""
