The Chi-Rho symbol combines two Greek letters into a symbol that looks like the letter X placed over the stem of the letter P. The Greek letters chi and rho are found at the beginning of Χριστῷ, which translates to “Christ” in English. The Chi-Rho is also called the Christogram because it is a monogram of Christ. This symbol gained popularity representing the name of Christ during the time of Constantine in the fourth century AD.
