Ineffable

The word just came to me - ineffable. Why? A sacred object beyond description. A presence beyond the need for words.  From a Catholic or a literary tradition of accurate expression? Look it up?  I submit the Freiburg Cross (A.D. 1280 -1300) as candidate for the ineffable. Countless expressions of the events and beliefs in a faith represented on a gold cross elaborated with finely carved renderings in gold, silver and enamel. Two-sided, no space is spared characters and symbols filled with religious mneaning. Of course, a Beatific vision ( real or imagined) of God defines the unspeakable, but believers in the Middle Ages couldn't wait. They rendered the ineffable on a cross available to the common and uncommon alike.
