Lord's title monogram
The more familiar monogram IHS (IHS) is the abbreviated form of the Greek word for our Saviour's human name, Jesus, IESOUS. The first two and the last letters are those used. Sometimes this is written "IHC." The two forms are synonymous, the C being simply another form of the Greek S. Sometimes the letters are intertwined, the I being lengthened and formed into a cross by a bar at the top.
IHS monogram
These three letters are often read as signifying the Latin words, Jesus hominum Salvator, that is, "Jesus the Saviour of men"; but appropriate and beautiful as this reading is, it is not the original meaning, but an afterthought, and is said to have been first suggested about the year 1380.
Another monogram contains the initial letters, IX, of our Lord's full name, Jesus Christ, in Greek. The X (Chi) is combined with the I (Iota). Sometimes a horizontal bar is placed through the middle of the figure, thus giving the initials of our Lord's full name, united with the cross.
