"Rendl´s work shows the structural reality of the world, in whose movement form emerges but ephemerally, not unlike the foam of breaking billows. And yet, this foaming form is a necessary aspect of all transience."
"Contemplating the pictured walls so thoroughly mirroring Rendl´s cosmos, the viewer may well learn what a patient eye and a caressing hand may create, namely re-spell (reenact) the unity of numbers, symbols, letters, lines, and mandorlas – all these belong to the greatest wisdom that our present, so estranged from images, can draw from the bright darkness of a distant past."
Prof. Dr. Otto
"...these displays are as pure as waterfalls of love".
