Obviously the nuns of the church did not make a simple choice of one or the other design, but went rather for a mix-and-match of elements: the upper half largely following the oil sketch in the Royal Collection and the lower half that in the Hermitage. The iconography differs: this is an Assumption; the Hermitage painting a Coronation with music-making angels; this one has a sarcophagus tomb, that a cave in the rock. The most interesting variation occurs in the lighting: the Hermitage panel shows a torch-lit, nearly night scene with a golden heaven; this panel shows a naturally lit evening scene with an azure heaven. Blue is the keynote colour.
