The Catholic Encyclopedia (1911) traces monstrances to the 13th century, and the sunburst style to the 15th (see Ostensorium). It doesn’t say, however, whether the sunburst shape was based on something else, or if it was at least perceived as an original design. The CE only gives the practical reason that the sunburst shape (as opposed to an ark) was “better adapted to the object of drawing all eyes to the Sacred Host itself.” Was it also chosen because Christ is the “Sun of Righteousness,” or is that coincidental? Was there an association then (1400s) with royalty, or did that come later?
