King Louis IX lived an unusually prayerful and pious life and pursued a foreign policy in tune with his beliefs – supporting the papacy, encouraging union with the Orthodox churches, and strengthening the position of the faltering crusader regimes in Palestine.
He is normally portrayed with a crown and/or other signs of regal status, like other sainted kings. Unlike them, he can be identified by the French royalty's fleur-de-lis symbol, which may appear on his sceptre, as in the first image at right, or on his clothing, as in the second. El Greco's painting further distinguishes him from other sainted kings by giving him the Main de Justice, the "Hand of Justice" sceptre used in the French coronation ceremony (Godefroy, 452).
The second picture is also an example of images that put him in armor, in recognition of his service as a crusader. As a third-order Franciscan, he is paired in that picture with St. Anthony of Padua.
Despite his connection with the Franciscans, King Louis is rarely portrayed as one of them. An exception is the third image on the right, where he wears sandals and the Franciscan habit under a rich cape with a fleur-de-lis collar.
In the apse mosaic at the Church of St. Francis in Manhattan, St. Louis holds in his hands the crown of thorns believed to have been worn by Jesus on the Cross, which he obtained from the Latin Emperor of Constantinople and for which he built the Sainte Chapelle in Paris (Butler, III, 395).
