[St_Thomas_Aquinas]

Most Catholics know that IHS is taken from the Greek spelling of Jesus' name, although some Catholics mistakenly believe that it's short for "In His Service."

Every Catholic church has IHS and/or XP inscribed somewhere, usually in prominent locations in the church.

That’s the case today, and for the last couple of centuries, but way back ‘when’ folks had less money and there were far fewer ornaments ~ once Spain and the Hapsburg ‘empire’ became enormously wealthy with plenty of silver available to buy art, every noble and notable in their society got a personal portrait ~ or sometimes heroic painting done! Philip of Castile was particularly enamored of that monogram and created one for himself that was remarkably similar ~ http://upload.wikimedia.org/wikipedia/commons/f/fa/Royal_Monogram_of_King_Philip_I_of_Castile%2C_Variant.svg
