The Latinized version of the letters IHS (Iesus Hominum Salvator) were extremely popular during Byzantine times.

Ιησούς Ήμέτερος Σωτήρ (Jesus Our Savior) is another usage of the three Greek letters ΙΗΣ.

[3] Iesus Hominum Salvator became the official Christogram of the Franciscan Order during the fifteenth century.

Greek painter Andreas Ritzos used the Christogram IHS in one of his most important icons.

The icon was first mentioned in the will of Cretan scholar and noble Andreas Kornaros in 1611.

In more recent years, the painting became part of the collection of the Byzantine and Christian Museum in Athens, Greece.

In the next portion of the letter H John the Evangelist appears in his traditional position as part of the crucifixion sequence.

The sarcophagus illustrates deeper space clear diagonal lines and the holy towel is weightless in a spaceless setting.
