The letters "JHS" on a cross are a very common Christian symbol. They are a Latin-based abbreviation or *monogram* of the name of Jesus. Here's a breakdown of the most common interpretations:
* IHS: This is the *most likely* and historically accurate meaning. It's a Latin abbreviation of the Greek name for Jesus, "ΙΗΣΟΥΣ" (Iēsous). In Latin, this is rendered as "Iesus." The letters IHS are simply the first three letters of this Latin spelling.
* JHS: While less historically accurate, the letters J, H, and S, being similar to the Greek letters, became more common as the printing press developed and spread during the 15th century.
* Popular (though less accurate) interpretations: Over time, the letters have also been interpreted with devotional meanings such as:
* Jesus Hominum Salvator: Latin for "Jesus, Savior of Mankind."
* Jesus Habemus Socium: Latin for "Jesus, we have you as our companion."
* In Hoc Signo (vinces): Latin for "In this sign (you will conquer)". This is a reference to the vision of the Emperor Constantine before the Battle of the Milvian Bridge.
In short: While devotional meanings exist, JHS is most likely a variation of the Latin abbreviation of Jesus' name.
