IX monogram

The IX monogram or XI monogram is a type of early Christian monogram looking like the spokes of a wheel, sometimes within a circle.

The IX monogram is formed by the combination of the letter "I" or Iota for IHSOYS (Ιησους, Jesus in Greek) and "X" or Chi for XPISTOS (Χριστος, Christ in Greek). The spokes can also be stand-alone, without the circle. These monograms can often be found as ancient burial inscriptions.
