Artur Balder writes, in relation to the work of Castejón, that "an indispensable condition of the Gesamtkunstwerk, with a base of either visual, literary, or musical representation, is its timeless condition, its ability to withstand the test of time itself by rising instead of sinking into the spasm of momentary fashion, and perish with it a few years, and only to be seen in that context, as in a narrow place of history. However, Castejón, next to the absolute hero in its representation of humanism, can be attributed, as an artist, as Juan Gil-Albert described, "in whose light the depths of so looming giant men, that I was forced to retain breath and meditate."
